It’s hard to follow the story. Sounds like he is at a shop diagnosing it. The shop could have purchased an engine from ford and installed it themselves before releasing back to owner???
I know a guy that graduated from Ithica High School in 2004 and went on to Cornell University. Seems he might have had some input on some particle acceleration thingy. Then he went on to Penn state and now lives nine miles from there and we are all grateful and enjoy his videos. GREAT VIDEO!
When i was at ford during the great Triton disaster years, Ford ran out of new 2Vs and 3Vs because of so many issues, we use to get engines from Jasper, S&K and one other i can't think of and at some point about half of them were coming in bad, no compression, ticking, no oil pressure ECT... the owner broke down and started buying trucks (junk and used) just to pull engines from so we could rebuild them in house and line the back wall of ready to go engines to swap because he got so tired of all the come backs. How i got lucky to have been working at a dealer at the time that cared that much, i don't know, but good luck finding one like that now.
I am grateful for all the time you invest in these videos Mr. Ivan. You inspire me a lot to continue in this field, I am young and from Latin America. But despite the difference in languages I really enjoy these videos and I learn a lot. I hope one day to be like you.
Yep, head gasket leaking between cylinders and coolant passages on bus one. Bus 2 is likely to have a failing head gasket as well. My guess is a broken head bolt or 2.
Maybe they bolted down warped heads.... I was thinking in correct cam, or switched firing order... at one point even thinking someone tweaked valves during assembly... Ivan in a combustion engine genius!
i was thinking (based on the reused coils, that were not in a good condition) that they maybe reused the head gasket and or bolts, this would not surprise me with what i observed in this video.
I bought two old rusty 2001 F250 V10s from a customer of mine for my salvage yard and had to drive them there. One of them was towed to my shop awhile back after the oil cooler line rusted thru and blew all the oil out on the interstate and seized the engine and I basically told him it was junk so he towed it back to his place where it sat for a couple years but after considering how it locked up suddenly vs having no oil for thousands of miles and damaging the engine over a long period of time, I figured it would probably turn over and run so I pulled all 10 plugs, sprayed a few cans of penetrating fluid into the cylinders and came back a week later and did the same thing. Put a breaker bar on the crank bolt and a pipe on the handle and it still wouldn't turn until I gently tapped on the harmonic balancer with a ball peen hammer and it moved a thousandth of a degree which meant the crank bearings were free but the rings were stuck so I tried to move the crank back and forth that little bit and it finally turned over and felt real nice with no rough spots. Put a new starter on it, hooked up a couple extra batteries in parallel and cranked it several times to blow the fluid out of the cylinders then did a compression test and they were all at or above spec. Blew everything out with compressed air and put it all back together and got it to run on brake cleaner since the fuel pump was shot. Replaced the fuel pump and drove it 50 miles to my salvage yard no problem! Those 2V non VVT Ford modular engines are damn near indestructible. I wouldn't have bought them if they were 3V VVT pieces of junk. Gonna drive that this winter and save my 2002 F250 7.3 from rusting any more. What I save not having to buy DEF makes diesel fuel affordable.
The shop/dealer that did the work will probably claim the engine was overheated. I've observed this on a 4.2 Fred Jones I installed in a 97 F150. As soon as the engine reached operating temp it started misfiring and steaming out the exhaust. The dealer tried to say I overheated it.
All reman engines that I have used have temperature “fuses more or less” that will show a over heat situation. They are usually built in to the softplugs.
@@joemilton7552Yes, but if you see the temp rising into an overheat situation you still have some responsibility to prevent damage, or it may have been run low on coolant.
My first thought was that the ignition coils were bad, then when the compression test told about bad compression I thought that it was assembled with bad valve clearance, which happens. But the coolant leak tells me that it wasn't properly assembled. Modern engines have torque to stretch bolts, and reusing them will lead to failures. The engine builder might have failed to check that the heads were plane before assembling too. So I wouldn't be surprised if the dealer cheaped out too much.
Would loved to hear the conversation about the first diagnosis. that was a great diagnosis... did they ever get back to you on why the fluid was getting in the cylinder?
If the reman engine didn't get new coils, what else didn't it get? Multiple engines with similar issues says something likely wasn't done right during assembly. The coolant leaking is pointing to something with the head. As others have stated, maybe the bolts just didn't get torqued properly - amount, order, or both.
Lot of hate on the V 10 in the comments. I own 4 of them from 99 to 08. 345,000 miles on the 99. A few coils, routine maintenance, all OEM fluids, synthetic oil Motorcraft filters. These trucks all work, no soccer mom rigs. We do all our own service. I love these engines.
Wow! A sub 50 psi cylinder compression that fires seams mysterious. The shop that installed these needs a test to check from air cleaner to tailpipe. Maybe a shop vac with a PHAD pressure transducer.
I don't know how but this video from ivan got past me So I may bet late to the party 😊 First I keep hearing new engine thrown around while I think I heard ivan actually say it was a new short block which means the shop doing the replacement was responsible for the heads, the installation of the heads, et cetera. Regardless,, the fact that Ivan found a cylinder full of coolant absolutely points at your classic blown head gasket or. some kind of mechanical issue, such as a cracked cylinder wall, piston et cetera. If it was a long block, then the engine rebuilder is responsible, if it was a short block, the engine installer is responsible since tjey are tje.ones who intalled the heads. Either way, the shop that was ultimately paid to do the work is responsible to make the customer whole. And they are the ones who need to go fight the issue with either the installer or the rebuilder. Hope y'all have a great day! Heading to the beach to do some surf fishing and give the dog a good walk.
Wow, I'm at loss for words for fake giving brand new engine to find major faults in it. Just wow. So you worked on 3 busses ? Damn, no question it needs to be warrantied!! Found on road dead lol. Hahaha. Nice diagnosis on all those v10s. It's nice to have the doghouse removed you work on them! Great video Ivan!!
Are those Jasper engines or Ford engines. Either way, coolant in the chamber is definitely problem one with possible more problems to come! Both those engines need replacement. A note here. I just remembered. We had Ford trucks with V10's and when a new Ford engine came in a crate, it had new Motorcraft spark plugs and new Motorcraft ignition coils. They also had new crank and cam sensors. Sometimes new Ford exhaust manifolds were ordered cause the old ones were leaking, but always came with new plugs, coils and sensors. Good one Ivan!
Ivan, this was an entertaining and educational video. Thanks. I must admit that when the title showed on my Subscriber notification, I thought you had gone pretty far off base, but I was wrong. Your diagnostic tools and techniques are not limited to just autos. Nicely done.
My guess on first one is pull that head of. Inspect head, maybe pooched head gasket or warped head… all that stuff got pushed out the exhaust and finished off the Cat. Love the transducer diag
The owner of the RV shop I worked at for a while has a motor home with the V10. He's on the third engine in 2 years. Factory motor was a Ford and it dropped a valve. Last 2 were Jasper.
I guess the dealerships don't have time to care, but as an independent, all it takes it one new/reman longblock assembly coming apart for you to buy them, tear them down, and redo everything yourself like you were building it from scratch. The number of times I've found improperly torqued fasteners blows my mind.
Good Day Ivan, to me if cat was plugged it would reflect high back pressure on all cyl in the bank of driver side, having said that just by clear flood crank the engine is shot and to make it worse with bad coils on top of it. Why not install new coils on this new engine since it's a pain to work on with the engine in place.
On my 2002 2v 6.8L I used accel coils. Only' 1 ever failed and it was warrantied. The motorcraft were substantially more expensive and more prone to failure. My coils always failed soft leading to fish bite misfires, other modular engines that I dealt with like my mother's 4.6L Lincoln only ever had coils fail hard leading to dead misses.
Ivan. Loved the diag. I guess that Ford used to make quality products - not anymore? I'm guessing the quality and knowledge of the techs. Just like in electronics: You hear, "what is a MOSFET? " AhhhDuhhhh. E=Mc2
Ford's reman engines are not known for their reliability. I had a 6.0 powerstroke that I installed at the dealer and the customer drove it on a trip afterwards. I was notified a few days later that it was coming back, customer said it was blowing oil out of the dipstick tube. Of course everyone was pointing the finger at me but after tearing the engine down, it had grenaded two rods/pistons. The truck still ran, just smoked like a freight train. I hope your customer gets his diag money back and his engines repaired properly. I have heard that there is a shortage of V10 reman engines. Our last V10 had to get rebuilt instead of a reman due to that reason.
Back in 1960 when I was 17 my twin brother and I managed to get a 1940 Chevy 6 cyl half block, went to the junkyard and got an old worn out head, hand ground the valves and put it together without any help from anybody. It ran like a top and even started at 40 below zero. Are there no good mechanics left for the dealers? I took my 2008 Nissan to the dealer and they couldn't find out what was wrong with it, even though I know what it is. I'm still looking for a way to fix it.
There are many videos on Ford 'quality' remanufacturered engines having problems. Concerned customers may notice something strange with the long block, only to disassemble and find out there is a complete disaster inside. Scratched, worn and out of tolerance crank journals. Broken bolts left in the block. AND mismatched piston sizes with one or two oversized pistons but all the others are standard bore. Thats quality right there! Will it work? Sure, maybe. But your spending a lot of money for a factory rebuild that you would expect to be better than this...
1) Checking spark like that is very wrong. Can fry coil, and if the spark jumps to a wiring harness, fry computers. 2) Prior to checking compression you should have cranked with the injector disconnected to blow out all the unburnt gasoline 3) #1 thing to check after an engine swap with misfires is the firing order where ignition cables, coil control plugs and or injectors are on the wrong cylinder.
I reckon you've come across an American strain of a bug that I've often seen crop up here in the U.K. - it's rife in Corporate deals or to firms with large inventories - poor quality kit or services sent in relying on no one doing much checking. It was tried on me once I'm sure - on calling my local main Ford dealer for a guaranteed recon engine, I was offered a so called "brand new spanking York" in an original crate with docs for very little more money so did the deal. First suspicious thing - warning label to fit a new oil pump - in the sump (oil pan) on this model - called the dealer "are you sure this unit is NEW?" I didn't believe his "yes" so fitted the unit on a test bed - no comp on two cylinders (at least this saved me some work) on calling the dealer with the good news - he said he'd put into Ford's for diagnosis, I then quoted him some of our laws on merchantable quality etc., eventually - after much argument - he sent over another unit exactly the same as the first and the bill!!! I tested the second engine as if I worked for NASA before it went anywhere near a truck - it was fine and carried on working for over ten years. The dealer and I ended up in legals - all huff and puff from him, stack of evidence from me - he took it all the way to a court appearance and then failed to show up! The dear old Judge said "we take a very dim view of this kind of thing" and awarded me full costs.
Question Were these engines a short block or long block? That points out to a bad rebuild from whoever rebuilt it or remanufactured it. I also suspect other issues to be present as well. The dealer supplier likely contributed to it and the dealer would have to go to the rebuilder to be reimbursed for the work.
If the dealer did it they should’ve sold a Ford reman long block. That gives them another warranty with the engine. The fact the dealer is turning them away and the poor quality of the reman makes me feel like there is some cost cutting happening somewhere. Maybe cheap wholesale deals on NonFord reman engines, sourced by the bus company. Hence why the dealer washed their hands of it. Just my 2¢
Did the shop only do a short engine swap, using heads etc. from the original engines? That could explain badly fitted heads, valve clearances messed up etc. if whoever did the work was inexperienced (or jut bad)..
So this company is obviously a multi-million dollar Ford customer and he has to call in a third party expert (Ivan) to diagnose warrantee problems? What is going on with Ford service! This is more than disturbing.
@@frankvucolo6249 really? If a multi-million company as you say is full of incompetent employees that are unable to do the job they were payed to do (in this case maintaining their vehicles) and need to call a third-party (which probably found on UA-cam) I would say they hired not the best men for the job... if this possibile answer to your question disturbs you than maybe you shouldn't ask it... what's your possibile answer?
@@alexdragomirescu5084 do you know what diversity hiring means? Your original comment implies that there is a connection between the ability to be a competent mechanic/technician and one’s age, race, gender, religion or sexual orientation. If you want to say that the dealership is hiring poor mechanics, that is a valid explanation. It’s when you attribute it to diversity hiring that you cross a line into the absurd and to an unhealthy bias. Perhaps you misused or misunderstood the term?
@@frankvucolo6249 might have misunderstood the term in it's full meaning, but I wouldn't be surprised if the latte sipping girls from old "a day in a Twitter employee life" is managing at least the HR department at that company :)) The problem always starts from the top to down.
My 2012 f450 bucket truck has the v10 and just developed a rattle and misfire. The rattle stopped and the misfire got worse. 143k miles. My company has decided to replace the engine (with a Jasper) instead of surplusing the truck. I hope it turns out well lol
As an old, retired mechanic. not too up to date with electronic equipment, would it have been just as easy to start with the basics, providing things can be got at, with my old compression gauge, vacuum gauge and pull the coils and look at spark length and colour as well as coolant pressure test?
Given the age I would say poorly installed heads and gasket, poorly machined surfaces, etc. It would be interesting to have the engine on a stand and do a torque test on the head bolts. These are odd engines and I suspect they are sent out to be rebuilt as these buses and maybe trucks put the miles on.
Ivan can I ask you a pretty detailed question and maybe spit ball me some ideas, I’m not the best at network problems but have learned a lot from you and really wanna figure this one out. It’s a late production 2018 F250 6.2 crew cab, somehow it starts and drives but literally nothing else on the car works. Topology report shows HS1 and HS2 as the only 2 trees. You can communicate with the PCM, BCMII, and BCM-B on the HS1 network and then every single other module on the car is down, the entire HS2 tree. On wiring diagram it shows the car has HS1 HS2 HS3 MS1 MS2 and MS3, all of those networks go into the gateway module which is the back side of the DLC connector, it’s a little module box that the dlc comes out of. From the front side of the dlc when I scope HS1 the network looks fine but when I scope HS2 it looks like the network is being pulled down most of the time. First of all how come all of these networks go into the gateway module but topology shows all of the networks on HS1 or HS2? How would you go about taking the next step on something like this? Any ideas would be appreciated
i am a Holden whose going to tell you now that im Australia that's a Stephen Ford form,I learned to avoid that mechanic as far as having one of theirs touch my car. I replaced the cylinder head gaskets in my 5.7 litre Chevrolet LS1 V8 engine almost 5 years ago since I replaced the hydraulic lifters meaning that I had to unbolt the cylinder heads to replace them & that form of employer who had me employed as a casual/contractor hasn't wanted to employ me as an electrician ever again. So what else can I say ss a Holden ? I think that Ford drew a circle around the problem !
Great diagnostic Ivan! Hmmm. #1 who sources these engines? Could they be "counterfeits" due to supply and demand where Ford or dealership or both use a 3rd party supplier without quality verification or lowest cost,etc? We've seem knock off parts in oem boxes where even a distributor didn't know they weren't true oem. A short or a long block engine might not have been received from a certified supplier vendor? Hey with all the corruption going on in industry or the support supplier network....Id wager at the end of the day, NOBODY bothers to check the quality or adherence to minimum standards of conformance! I worked as a machinist, assembler, taught SPC, spent 8 of my 27 years in QA as a grade A certified inspector covering everything from the inspection/tests of the raw materials to the finished product and everything in between! There is no way such a massive mistake could ever get this far UNLESS NOBODY EVER audited the supply chain. Holy S%*t!!! We are ALL in deep do-do......and things are about to break down like no one has EVER SEEN BEFORE. Thanks for all you do, Ivan! We need more individuals with your skillsets if we are to survive this automotive apocalypse!🕵🙏😍
Halfway into this I had the thought that bus is thirty or more feet long with an exhaust pipe a little long than that with a cat of some kind a muffler and some kind of resonator. Must build up a lot of pressure not to mention standing waves and that sort of thing. Prob has nothing to do with it. Since I'm here halfway and open to guesses timing chain? Harness plugs going to the wrong coil? Back to the real action.
Was wondering this too with the apparent exhaust restriction. He also mentioned the cat was plugged but didn't see him check that, maybe did some checks off camera?
@@joemilton7552 Back-pressure. I was able to figure that one out without any tools except my brain on a 2003 Jeep Liberty. I even mentioned it to another person that had the problem.
Hello Ivan. Seems like you're the person to ask this after watching your videos. I have a 2006 Jeep Grand Cherokee 4.7 and getting various code on my cheap scanner ike P0882, P1603, ABS no comm, etc, etc. I live in PA but am about 130 miles from you. If I was closer, guess where my Jeep would be. I have an electronics degree and about over 40 years of shade-tree automotive repair experience, but never had a decent scanner. I need to get deeper into these issues and was wondering what scanner would suffice? I was looking at that King Bolen but is there anything less expensive that will do everything that I need? I've searched UA-cam far and wide and it seems like alot of the scanner videos, well, it just seems like they are trying to promote the free scanner that they got. I'm also looking at getting a Picoscope and I've done all I can with my Fluke DVM so anyway any help in the scanner area would be appreciated.
Wasn't that 2012 era that these V10's would blow the spark plugs out of the cylinder head?? A friend of mine had a pickup with the V10 and nothing but troubles of having to take it back to the dealer and if not the spark plugs were being blown out, stripped threads and 3 different brands of spark plugs and if that wasn't enough, coils had to be replaced and if that wasn't enough, it was problems upon problems, three and four problems time and again; well that truck of his spent nearly 3 months at the dealer. This truck didn't even have 60K miles on it and once my friend had enough of the dealer's bs, he flat out got rid of it and bought a Dodge Ram Diesel for his new work truck. I'd have to say that these V10's weren't worth the powder to blow them to hell! He had a fortune in repair bills that wasn't covered under warranty either!! When things go so horribly wrong with these V10's, get rid of them as fast as you possibly can, is what I say! They tend to be absolute junk and to just think of just how many vehicles had this engine is even more scarier yet! We're talking about some motor homes, buses of course, pickups and yes some cars as well and to actually trust these types of repairs being done by the dealers is even scarier yet!
Very interesting. I would guess that perhaps the clogged cats caused the damage if they were ran for a while.Whoever did the work should be responsible. 👍👍🇺🇸
wonder if they did a break in procedure on the engines,, also what kind of maintenance is the bus barn doing if the coils are all ratty. would have like to seen the condition of the oil.
Yes. Initial light duty runs in on a bus full of kids travelling up hill and down dale. Would be easy to run it in. Same as for diesel trucks. Run them empty without any load for the first 10000 miles. I am sure everyone would buy one. Same for the bus. Retired mechanic/machinist in Land Down Under.
I think it is reasonable with a pressure transducer in a cylinder that is just idling. Remember, you are not cranking and building up pressure in a pressure gauge with a one-way Schrader valve in it with the throttle held wide open. This is the pressure in the cylinder on one stroke: all of the pressure is relieved each time the exhaust valve opens and none is stored between strokes and the air sucked in is at intake manifold pressure.
Its just so hard to get good stuff anymore. Yes, I understand stuff can happen. Seems like every time I turn around. Stuff just get worse and I'm not even an Auto Anything.
If it's a 265psi pressure transducer, then why does the pico setting only say 135psi? (If I'm wrong, please correct me-- but you can see the setting above every waveform you show on screen). Even your "known good" said it was only 75psi.. I'm not even sure an engine can run at all that low. You typically see 120psi to 150psi. 135 (pico setting) is virtually half of 265 (transducer rating).. so if you double your readings, that would make a lot more sense. The cylinder with 75psi would be actually 150psi.. and the 45psi cylinder would be actually 90psi... which is definitely a bit low. The cylinder full of water is a smoking gun though. I just wonder if they re=used the old head bolts maybe? Or maybe they didn't even get torqued down properly? strange video
Sad...#2 bus will have its head gasket problem when the warranty is expired. I'd complain and pressure them to replace this engine as well, likely from the same bunch of motors as the first one. There's too much money on jobs like these to be a picky dealership..."a little rough" shouldn't be there on good money for a new engine.
I agree. If Ivan can prove that the miss on 4 is not fuel or spark related, it should go back. Period. Also, in finding the coolant issues of bus #1, I would pressure test the heck out of #2 with that bore scope. I bet he finds coolant seepage. If those mills are official Ford remans, that is a real quality control issue. If they are outsourced for Ford, (local shop etc) I as a fleet customer would push the issue as high up as I could go with Ford.
@jamesofallthings3684 yep cheers. Just so amazing that something can show you the exact pressure in a cylinder without actually going in there. Cheers, I want one.
I was interested in your pressure transducer set. Problem i have is you mention odd increments, which will not read correctly with my Snap On scope. I am also aware that i need the "specs" to calibrate it to my Autel MP408. Do you supply the necessary spec sheet?
That coolant was a surprise, were they buying engines that were from a scrap yard and all of them had a warped head due to overheating. i blame the dealer ship, no reason lol.
Judging by the look of that gasket, I'd say that or they used the old bolts. Or both. Or didn't check for flatness, or etc. I don't see how it ran at all. With all the engines I worked on, and there hasn't been that many, I never had a problem, it was always the other guy that didn't know what he was doing when there was a problem. (Like not putting in the oil pump driver rod in a 1954 Ford).
It is pretty sad when the stealership installs a multi thousand dollar engine and lets it leave running worse than when it arrived. Makes you wonder if the problem is deeper than the place replacing garbage with garbage doesn't it?
I´m kind confused, why that company have gasoline engines in their citybuses, when modern diesels are more effficient than gasoline, and also last longer (normally), or is it something with emissions in there? If it`s fuel issue, dont you have winterdiesel there, as we have here in Finland, goes nice down to -30c arcticdiesel even lower. Anyway that kind of engines should never leave any shop, and even more from dealer, that is not exeptable, rebuild or new.
Groovy! A bus 🙂 Crazy fault on a supposedly new engine! Crappy engine swap by dealer! Superb diagnostic, Ivan! Pressure transducer is an absolute must! Were the cylinder heads properly torqued?
Great job Ivan. You were all over this pig. LOL. I think you might have found a dozen more problems with it if you kept going. They must have gotten these engines out of the junkyard without any verification.
Ivan, I'm not a New Ford man, love Chryslers and older Chevy 5.3s,. As far as I am concerned, most newer Fords are design-wise "JUNK". Ford has taken over the mantel of RECALL KING! They really make too much junk today, period! Somebody messed up those engines so the Bus maintenance supervisor needs to get to the bottom of this situation or advise the fleet manager to purchase better vehicles.
Whats even harder to believe is the dealer shipped them back out to the customer like that ! totally unacceptable in my book !
It’s hard to follow the story. Sounds like he is at a shop diagnosing it. The shop could have purchased an engine from ford and installed it themselves before releasing back to owner???
@@mph5896 Even I, Finish guy can follow this, and also read what Ivan wrote, how can`t you? Assuming you are american ? Am I wrong?
Ivan is working at the bus fleet maintenance facility/garage. The maintenance facility farmed the engine replacements out to the Ford dealer.

Good morning everyone...watching here in Jamaica 🇯🇲......at Marvin's Auto diagnostic
Hail.
I am grateful for all the time you invest in these videos Mr. Ivan. You inspire me a lot to continue in this field, I am young and from Latin America. But despite the difference in languages I really enjoy these videos and I learn a lot. I hope one day to be like you.
Thanks for sharing , I can see at minute 3:10 no shoes Required 😊
That pressure transducer makes a big difference in diagnosis.
Never seen one used before, what a superb way to see inside a motor. Makes my standard pressure type gauge seem like a waste of time.
Yep, head gasket leaking between cylinders and coolant passages on bus one. Bus 2 is likely to have a failing head gasket as well. My guess is a broken head bolt or 2.
Maybe they bolted down warped heads....
I was thinking in correct cam, or switched firing order... at one point even thinking someone tweaked valves during assembly...
Ivan in a combustion engine genius!
i was thinking (based on the reused coils, that were not in a good condition) that they maybe reused the head gasket and or bolts, this would not surprise me with what i observed in this video.
Love it. Another great video Ivan. There's not much I haven't seen you work on, maybe a train. Keep working hard and teaching us new things.
Great video! I would recommend that an acceptance test be performed by the shop and witnessed by the customer before taking delivery of the engines.
And that is a GREAT idea!
Or test all from air cleaner to tailpipe.
I bought two old rusty 2001 F250 V10s from a customer of mine for my salvage yard and had to drive them there. One of them was towed to my shop awhile back after the oil cooler line rusted thru and blew all the oil out on the interstate and seized the engine and I basically told him it was junk so he towed it back to his place where it sat for a couple years but after considering how it locked up suddenly vs having no oil for thousands of miles and damaging the engine over a long period of time, I figured it would probably turn over and run so I pulled all 10 plugs, sprayed a few cans of penetrating fluid into the cylinders and came back a week later and did the same thing. Put a breaker bar on the crank bolt and a pipe on the handle and it still wouldn't turn until I gently tapped on the harmonic balancer with a ball peen hammer and it moved a thousandth of a degree which meant the crank bearings were free but the rings were stuck so I tried to move the crank back and forth that little bit and it finally turned over and felt real nice with no rough spots. Put a new starter on it, hooked up a couple extra batteries in parallel and cranked it several times to blow the fluid out of the cylinders then did a compression test and they were all at or above spec. Blew everything out with compressed air and put it all back together and got it to run on brake cleaner since the fuel pump was shot. Replaced the fuel pump and drove it 50 miles to my salvage yard no problem! Those 2V non VVT Ford modular engines are damn near indestructible. I wouldn't have bought them if they were 3V VVT pieces of junk. Gonna drive that this winter and save my 2002 F250 7.3 from rusting any more. What I save not having to buy DEF makes diesel fuel affordable.
DEF is pretty cheap…$15 takes you 5,000 miles or so. Not saving much…
@@tylermacconnell217 it's the principle of having to use it in the first place or you can't drive the vehicle. You must not like freedom very much.
I don’t mind DEF at all…lets the engine use less EGR, which improves fuel economy and engine longevity. Now the DPF I will complain about.
5 gals of Engine Restore, and she's good to go !

Great video, Ivan!! They definitely aren’t making very good quality products nowadays! It’s really sad😢
Not making very good quality people either.
The galloping rhythm during a WOT clear flood crank is no bueno.
The shop/dealer that did the work will probably claim the engine was overheated. I've observed this on a 4.2 Fred Jones I installed in a 97 F150. As soon as the engine reached operating temp it started misfiring and steaming out the exhaust. The dealer tried to say I overheated it.
if the engine overheats, that's pretty much a problem with the engine, not the operator
All reman engines that I have used have temperature “fuses more or less” that will show a over heat situation. They are usually built in to the softplugs.
@@joemilton7552Yes, but if you see the temp rising into an overheat situation you still have some responsibility to prevent damage, or it may have been run low on coolant.
@@brianw8963 that was how I got the engine replaced the noob behind the counter wasn't aware they were installed.
@@Cheepchipsable Yes, but again there's a problem with the engine if it overheats to begin with, or runs low on coolant.
My first thought was that the ignition coils were bad, then when the compression test told about bad compression I thought that it was assembled with bad valve clearance, which happens. But the coolant leak tells me that it wasn't properly assembled. Modern engines have torque to stretch bolts, and reusing them will lead to failures. The engine builder might have failed to check that the heads were plane before assembling too.
So I wouldn't be surprised if the dealer cheaped out too much.
I just finished a complete timing job on a 2005 F-150 that was messed up by 2 other shops using aftermarket parts. Thanks Ivan!
Would loved to hear the conversation about the first diagnosis. that was a great diagnosis... did they ever get back to you on why the fluid was getting in the cylinder?
If the reman engine didn't get new coils, what else didn't it get? Multiple engines with similar issues says something likely wasn't done right during assembly. The coolant leaking is pointing to something with the head. As others have stated, maybe the bolts just didn't get torqued properly - amount, order, or both.
I wanna see Ivan run a route & pick up some passengers!!!
Great diagnosis you go above and beyond my friend great job.
I appreciate he's been uploading more videos lately
At least you are in the driver seat of the short bus and not riding in the back. 😂😂
Great video and diagnosis.
Enjoyed the video! Bad news for the owner though. Those Pico scopes are definitely worth owning.
Awesome Ivan that coolant flooded that cylinder great catch😊
Lot of hate on the V 10 in the comments. I own 4 of them from 99 to 08. 345,000 miles on the 99. A few coils, routine maintenance, all OEM fluids, synthetic oil Motorcraft filters. These trucks all work, no soccer mom rigs. We do all our own service. I love these engines.
Wow! A sub 50 psi cylinder compression that fires seams mysterious. The shop that installed these needs a test to check from air cleaner to tailpipe. Maybe a shop vac with a PHAD pressure transducer.
I don't know how but this video from ivan got past me So I may bet late to the party 😊
First I keep hearing new engine thrown around while I think I heard ivan actually say it was a new short block which means the shop doing the replacement was responsible for the heads, the installation of the heads, et cetera. Regardless,, the fact that Ivan found a cylinder full of coolant absolutely points at your classic blown head gasket or.
some kind of mechanical issue, such as a cracked cylinder wall, piston et cetera.
If it was a long block, then the engine rebuilder is responsible, if it was a short block, the engine installer is responsible since tjey are tje.ones who intalled the heads.
Either way, the shop that was ultimately paid to do the work is responsible to make the customer whole. And they are the ones who need to go fight the issue with either the installer or the rebuilder.
Hope y'all have a great day! Heading to the beach to do some surf fishing and give the dog a good walk.
Wow, I'm at loss for words for fake giving brand new engine to find major faults in it. Just wow. So you worked on 3 busses ? Damn, no question it needs to be warrantied!! Found on road dead lol. Hahaha. Nice diagnosis on all those v10s. It's nice to have the doghouse removed you work on them! Great video Ivan!!
Are those Jasper engines or Ford engines. Either way, coolant in the chamber is definitely problem one with possible more problems to come!
Both those engines need replacement.
A note here. I just remembered.
We had Ford trucks with V10's and when a new Ford engine came in a crate, it had new Motorcraft spark plugs and new Motorcraft ignition coils. They also had new crank and cam sensors. Sometimes new Ford exhaust manifolds were ordered cause the old ones were leaking, but always came with new plugs, coils and sensors.
Good one Ivan!
Ivan, this was an entertaining and educational video. Thanks. I must admit that when the title showed on my Subscriber notification, I thought you had gone pretty far off base, but I was wrong. Your diagnostic tools and techniques are not limited to just autos. Nicely done.
My guess on first one is pull that head of. Inspect head, maybe pooched head gasket or warped head… all that stuff got pushed out the exhaust and finished off the Cat.
Love the transducer diag
Good going! I didn't know V-10's were still around!
fair doos to you Ivan you will tak on every make and model
The owner of the RV shop I worked at for a while has a motor home with the V10. He's on the third engine in 2 years. Factory motor was a Ford and it dropped a valve. Last 2 were Jasper.
So he swapped a garbage engine for a couple trash engines.
I guess the dealerships don't have time to care, but as an independent, all it takes it one new/reman longblock assembly coming apart for you to buy them, tear them down, and redo everything yourself like you were building it from scratch. The number of times I've found improperly torqued fasteners blows my mind.
Good Day Ivan, to me if cat was plugged it would reflect high back pressure on all cyl in the bank of driver side, having said that just by clear flood crank the engine is shot and to make it worse with bad coils on top of it.
Why not install new coils on this new engine since it's a pain to work on with the engine in place.
On my 2002 2v 6.8L I used accel coils. Only' 1 ever failed and it was warrantied. The motorcraft were substantially more expensive and more prone to failure. My coils always failed soft leading to fish bite misfires, other modular engines that I dealt with like my mother's 4.6L Lincoln only ever had coils fail hard leading to dead misses.
And possibly cooking the PCM drivers!
Ivan, I lost it seeing you sit in that bus. I will never be surprised where you turn up. You should do undercover dealer tech episodes as a newbie 🤣
He would never be able to go undercover, being the smartest man in the room.
Ivan. Loved the diag. I guess that Ford used to make quality products - not anymore? I'm guessing the quality and knowledge of the techs. Just like in electronics: You hear, "what is a MOSFET? " AhhhDuhhhh. E=Mc2
Be really careful on V10 engines. After catastrophic failures metal can get in the plastic intake then come loose and fall into the new engine.
They can also get residual metal from a bad catalyst converter sucked into the combustion chamber and it can do mechanical damage inside the cylinder
That's pretty nuts - did yiy hear about the guy thst glued glitter on his junk ... pretty nuts ...
Ford's reman engines are not known for their reliability. I had a 6.0 powerstroke that I installed at the dealer and the customer drove it on a trip afterwards. I was notified a few days later that it was coming back, customer said it was blowing oil out of the dipstick tube. Of course everyone was pointing the finger at me but after tearing the engine down, it had grenaded two rods/pistons. The truck still ran, just smoked like a freight train. I hope your customer gets his diag money back and his engines repaired properly. I have heard that there is a shortage of V10 reman engines. Our last V10 had to get rebuilt instead of a reman due to that reason.
My nephew says the v10 is a v8 triton with two extra cylinders. The triton was the spark plug blower.
I’m not a ford guy but I do know that the v10 was based on the 5.4. Same bore and stroke but share no parts
Not good engines, such a dog.
If the cats were ruined by the bad new engine shouldn't the dealer contribute a portion of their replacement?
Back in 1960 when I was 17 my twin brother and I managed to get a 1940 Chevy 6 cyl half block, went to the junkyard and got an old worn out head, hand ground the valves and put it together without any help from anybody. It ran like a top and even started at 40 below zero. Are there no good mechanics left for the dealers? I took my 2008 Nissan to the dealer and they couldn't find out what was wrong with it, even though I know what it is. I'm still looking for a way to fix it.
Thanks Ivan!
There are many videos on Ford 'quality' remanufacturered engines having problems. Concerned customers may notice something strange with the long block, only to disassemble and find out there is a complete disaster inside. Scratched, worn and out of tolerance crank journals. Broken bolts left in the block. AND mismatched piston sizes with one or two oversized pistons but all the others are standard bore. Thats quality right there! Will it work? Sure, maybe. But your spending a lot of money for a factory rebuild that you would expect to be better than this...
The wheels on the bus go round and round !
thats enough Kamala Harris!
1) Checking spark like that is very wrong. Can fry coil, and if the spark jumps to a wiring harness, fry computers.
2) Prior to checking compression you should have cranked with the injector disconnected to blow out all the unburnt gasoline
3) #1 thing to check after an engine swap with misfires is the firing order where ignition cables, coil control plugs and or injectors are on the wrong cylinder.
On bus could you move a plug and coil form bus 1 ,swap tonics I know,but 1 engine is kaput,plus a very good use of a scope Ivan,thanks.
I reckon you've come across an American strain of a bug that I've often seen crop up here in the U.K. - it's rife in Corporate deals or to firms with large inventories - poor quality kit or services sent in relying on no one doing much checking. It was tried on me once I'm sure - on calling my local main Ford dealer for a guaranteed recon engine, I was offered a so called "brand new spanking York" in an original crate with docs for very little more money so did the deal. First suspicious thing - warning label to fit a new oil pump - in the sump (oil pan) on this model - called the dealer "are you sure this unit is NEW?" I didn't believe his "yes" so fitted the unit on a test bed - no comp on two cylinders (at least this saved me some work) on calling the dealer with the good news - he said he'd put into Ford's for diagnosis, I then quoted him some of our laws on merchantable quality etc., eventually - after much argument - he sent over another unit exactly the same as the first and the bill!!! I tested the second engine as if I worked for NASA before it went anywhere near a truck - it was fine and carried on working for over ten years.
The dealer and I ended up in legals - all huff and puff from him, stack of evidence from me - he took it all the way to a court appearance and then failed to show up! The dear old Judge said "we take a very dim view of this kind of thing" and awarded me full costs.
Wow that's crazy!! Cool video!!
Question
Were these engines a short block or long block? That points out to a bad rebuild from whoever rebuilt it or remanufactured it. I also suspect other issues to be present as well. The dealer supplier likely contributed to it and the dealer would have to go to the rebuilder to be reimbursed for the work.
If the dealer did it they should’ve sold a Ford reman long block. That gives them another warranty with the engine. The fact the dealer is turning them away and the poor quality of the reman makes me feel like there is some cost cutting happening somewhere. Maybe cheap wholesale deals on NonFord reman engines, sourced by the bus company. Hence why the dealer washed their hands of it. Just my 2¢
Did the shop only do a short engine swap, using heads etc. from the original engines?
That could explain badly fitted heads, valve clearances messed up etc. if whoever did the work was inexperienced (or jut bad)..
Yay!! Ithaca!! I’m in Ithaca as well!
So this company is obviously a multi-million dollar Ford customer and he has to call in a third party expert (Ivan) to diagnose warrantee problems? What is going on with Ford service! This is more than disturbing.
A result of diversity hiring maybe?
Congratulations, Alex. You just won the award for the most ignorant comment ever posted on You Tube. And that’s saying something.
@@frankvucolo6249 really? If a multi-million company as you say is full of incompetent employees that are unable to do the job they were payed to do (in this case maintaining their vehicles) and need to call a third-party (which probably found on UA-cam) I would say they hired not the best men for the job... if this possibile answer to your question disturbs you than maybe you shouldn't ask it... what's your possibile answer?
@@alexdragomirescu5084 do you know what diversity hiring means? Your original comment implies that there is a connection between the ability to be a competent mechanic/technician and one’s age, race, gender, religion or sexual orientation. If you want to say that the dealership is hiring poor mechanics, that is a valid explanation. It’s when you attribute it to diversity hiring that you cross a line into the absurd and to an unhealthy bias. Perhaps you misused or misunderstood the term?
@@frankvucolo6249 might have misunderstood the term in it's full meaning, but I wouldn't be surprised if the latte sipping girls from old "a day in a Twitter employee life" is managing at least the HR department at that company :)) The problem always starts from the top to down.
My 2012 f450 bucket truck has the v10 and just developed a rattle and misfire. The rattle stopped and the misfire got worse. 143k miles. My company has decided to replace the engine (with a Jasper) instead of surplusing the truck. I hope it turns out well lol
Jasper engines USED to be good. They are junk now. My company used them for years up until 10 years ago.because they kept failing at an alarming rate.
As an old, retired mechanic. not too up to date with electronic equipment, would it have been just as easy to start with the basics, providing things can be got at, with my old compression gauge, vacuum gauge and pull the coils and look at spark length and colour as well as coolant pressure test?
Given the age I would say poorly installed heads and gasket, poorly machined surfaces, etc. It would be interesting to have the engine on a stand and do a torque test on the head bolts. These are odd engines and I suspect they are sent out to be rebuilt as these buses and maybe trucks put the miles on.
Ivan, since your traveling, you might have to go fix that element for Jake. 😅
6:38 Look at the slant of the compression peaks, this is a major indicator that you missed.
Ivan can I ask you a pretty detailed question and maybe spit ball me some ideas, I’m not the best at network problems but have learned a lot from you and really wanna figure this one out. It’s a late production 2018 F250 6.2 crew cab, somehow it starts and drives but literally nothing else on the car works. Topology report shows HS1 and HS2 as the only 2 trees. You can communicate with the PCM, BCMII, and BCM-B on the HS1 network and then every single other module on the car is down, the entire HS2 tree. On wiring diagram it shows the car has HS1 HS2 HS3 MS1 MS2 and MS3, all of those networks go into the gateway module which is the back side of the DLC connector, it’s a little module box that the dlc comes out of. From the front side of the dlc when I scope HS1 the network looks fine but when I scope HS2 it looks like the network is being pulled down most of the time. First of all how come all of these networks go into the gateway module but topology shows all of the networks on HS1 or HS2? How would you go about taking the next step on something like this? Any ideas would be appreciated
It has been said that Ford went to the V-10 so they always had at least 8 cylinders functioning.
Wonder if the cat was plugged before the engine swap and caused some of these issues
Sounds like they should do a cat swap with the engine swaps im sure those buses do alot of idling
i am a Holden whose going to tell you now that im Australia that's a Stephen Ford form,I learned to avoid that mechanic as far as having one of theirs touch my car.
I replaced the cylinder head gaskets in my 5.7 litre Chevrolet LS1 V8 engine almost 5 years ago since I replaced the hydraulic lifters meaning that I had to unbolt the cylinder heads to replace them & that form of employer who had me employed as a casual/contractor hasn't wanted to employ me as an electrician ever again.
So what else can I say ss a Holden ?
I think that Ford drew a circle around the problem !
Great diagnostic Ivan! Hmmm. #1 who sources these engines? Could they be "counterfeits" due to supply and demand where Ford or dealership or both use a 3rd party supplier without quality verification or lowest cost,etc? We've seem knock off parts in oem boxes where even a distributor didn't know they weren't true oem. A short or a long block engine might not have been received from a certified supplier vendor? Hey with all the corruption going on in industry or the support supplier network....Id wager at the end of the day, NOBODY bothers to check the quality or adherence to minimum standards of conformance! I worked as a machinist, assembler, taught SPC, spent 8 of my 27 years in QA as a grade A certified inspector covering everything from the inspection/tests of the raw materials to the finished product and everything in between! There is no way such a massive mistake could ever get this far UNLESS NOBODY EVER audited the supply chain. Holy S%*t!!! We are ALL in deep do-do......and things are about to break down like no one has EVER SEEN BEFORE. Thanks for all you do, Ivan! We need more individuals with your skillsets if we are to survive this automotive apocalypse!🕵🙏😍
Jeeze, you are right, just buy a Tesla. I did.
didn't think those Furd V10's were supposed to live very long...LOL
Next on Pine Hollow Auto Diagnostics: this 1561 ox is running a little rough, just can’t pull the plow like it used to !!
We are back to the electric car, not the horse and ox.
Halfway into this I had the thought that bus is thirty or more feet long with an exhaust pipe a little long than that with a cat of some kind a muffler and some kind of resonator. Must build up a lot of pressure not to mention standing waves and that sort of thing. Prob has nothing to do with it. Since I'm here halfway and open to guesses timing chain? Harness plugs going to the wrong coil? Back to the real action.
Maybe the manifolds aren’t restricted. Maybe it’s a cam issue not allowing the exhaust valve to open fully?
What do you mean? The cam leaks coolant to the cylinder with the wrong timing?? 😅
He said that on cylinder number 10. Thought the manifold was restricted at higher rpm. @@rkan2
Was wondering this too with the apparent exhaust restriction. He also mentioned the cat was plugged but didn't see him check that, maybe did some checks off camera?
@@rkan2 O yea that have eyes but cannot see!
@@joemilton7552 Back-pressure. I was able to figure that one out without any tools except my brain on a 2003 Jeep Liberty. I even mentioned it to another person that had the problem.
Hello Ivan. Seems like you're the person to ask this after watching your videos. I have a 2006 Jeep Grand Cherokee 4.7 and getting various code on my cheap scanner ike P0882, P1603, ABS no comm, etc, etc. I live in PA but am about 130 miles from you. If I was closer, guess where my Jeep would be. I have an electronics degree and about over 40 years of shade-tree automotive repair experience, but never had a decent scanner. I need to get deeper into these issues and was wondering what scanner would suffice? I was looking at that King Bolen but is there anything less expensive that will do everything that I need? I've searched UA-cam far and wide and it seems like alot of the scanner videos, well, it just seems like they are trying to promote the free scanner that they got. I'm also looking at getting a Picoscope and I've done all I can with my Fluke DVM so anyway any help in the scanner area would be appreciated.
Wasn't that 2012 era that these V10's would blow the spark plugs out of the cylinder head?? A friend of mine had
a pickup with the V10 and nothing but troubles of having to take it back to the dealer and if not the spark plugs
were being blown out, stripped threads and 3 different brands of spark plugs and if that wasn't enough, coils had
to be replaced and if that wasn't enough, it was problems upon problems, three and four problems time and again;
well that truck of his spent nearly 3 months at the dealer. This truck didn't even have 60K miles on it and once my
friend had enough of the dealer's bs, he flat out got rid of it and bought a Dodge Ram Diesel for his new work truck.
I'd have to say that these V10's weren't worth the powder to blow them to hell! He had a fortune in repair bills that
wasn't covered under warranty either!! When things go so horribly wrong with these V10's, get rid of them as fast
as you possibly can, is what I say! They tend to be absolute junk and to just think of just how many vehicles had
this engine is even more scarier yet! We're talking about some motor homes, buses of course, pickups and yes
some cars as well and to actually trust these types of repairs being done by the dealers is even scarier yet!
Very interesting. I would guess that perhaps the clogged cats caused the damage if they were ran for a while.Whoever did the work should be responsible. 👍👍🇺🇸
PLEASE tell us theres a FOLLOW UP Video coming on what the remedy to this was/is. Does the dealer make the issue right???
wonder if they did a break in procedure on the engines,, also what kind of maintenance is the bus barn doing if the coils are all ratty. would have like to seen the condition of the oil.
Yes. Initial light duty runs in on a bus full of kids travelling up hill and down dale. Would be easy to run it in. Same as for diesel trucks. Run them empty without any load for the first 10000 miles. I am sure everyone would buy one. Same for the bus. Retired mechanic/machinist in Land Down Under.
THIS is the 3 valve and they had valve train issues. But a refurbished engine shouldn't have the issues.
You said it was ticking. Could there be something miss adjusted in the valve train on those cylinders be causing this?
Isn't 60 psi too low in any cylinder? I don't think that would be acceptable in a replaced engine.
I think it is reasonable with a pressure transducer in a cylinder that is just idling. Remember, you are not cranking and building up pressure in a pressure gauge with a one-way Schrader valve in it with the throttle held wide open. This is the pressure in the cylinder on one stroke: all of the pressure is relieved each time the exhaust valve opens and none is stored between strokes and the air sucked in is at intake manifold pressure.
@@justliberty4072 Thanks for the explanation, I did not think of that.
Its just so hard to get good stuff anymore. Yes, I understand stuff can happen. Seems like every time I turn around. Stuff just get worse and I'm not even an Auto Anything.
8:25 I'm wondering if the driver's side bank jumped time.
Edit: That's not the issue 😂
If it's a 265psi pressure transducer, then why does the pico setting only say 135psi? (If I'm wrong, please correct me-- but you can see the setting above every waveform you show on screen). Even your "known good" said it was only 75psi.. I'm not even sure an engine can run at all that low. You typically see 120psi to 150psi. 135 (pico setting) is virtually half of 265 (transducer rating).. so if you double your readings, that would make a lot more sense. The cylinder with 75psi would be actually 150psi.. and the 45psi cylinder would be actually 90psi... which is definitely a bit low. The cylinder full of water is a smoking gun though. I just wonder if they re=used the old head bolts maybe? Or maybe they didn't even get torqued down properly? strange video
Sad...#2 bus will have its head gasket problem when the warranty is expired. I'd complain and pressure them to replace this engine as well, likely from the same bunch of motors as the first one. There's too much money on jobs like these to be a picky dealership..."a little rough" shouldn't be there on good money for a new engine.
I agree. If Ivan can prove that the miss on 4 is not fuel or spark related, it should go back. Period. Also, in finding the coolant issues of bus #1, I would pressure test the heck out of #2 with that bore scope. I bet he finds coolant seepage. If those mills are official Ford remans, that is a real quality control issue. If they are outsourced for Ford, (local shop etc) I as a fleet customer would push the issue as high up as I could go with Ford.
Hey mate. Wouldn't an actual compression tester be more accurate? Just a question. Love your work mate. Have learned allot.
His pressure transducer is far more accurate than a scene in mechanical compression gage. Not slamming you but technology marches on 😊
It is an actually compression tester but it's measured electronically. Pretty awesome tool, but very spendy for diy.
@stevewhite3424 fair enough mate. Was just a question. Really amazing tool for sure.
@jamesofallthings3684 yep cheers. Just so amazing that something can show you the exact pressure in a cylinder without actually going in there. Cheers, I want one.
@@wheelersgarage8393 No worries 👍 👌
They must’ve bought and installed Jasper engines. 🤦♂️
That's crazy a blown head gasket on a brand new engine
I was interested in your pressure transducer set. Problem i have is you mention odd increments, which will not read correctly with my Snap On scope. I am also aware that i need the "specs" to calibrate it to my Autel MP408. Do you supply the necessary spec sheet?
Why did it need a new V10 after only 180,000 miles?
That's a good question. That seems a little poor for a Ford.
How do you test cylinder compression with clogged catalytic converter, you should have at least removed the Cat and run the compression test.
Must be a Tim Gentry deal! In flight missel repair!!!!!!!
That coolant was a surprise, were they buying engines that were from a scrap yard and all of them had a warped head due to overheating.
i blame the dealer ship, no reason lol.
Someone forgot to torque the heads.
...exactly my thoughts!
Judging by the look of that gasket, I'd say that or they used the old bolts. Or both. Or didn't check for flatness, or etc. I don't see how it ran at all. With all the engines I worked on, and there hasn't been that many, I never had a problem, it was always the other guy that didn't know what he was doing when there was a problem. (Like not putting in the oil pump driver rod in a 1954 Ford).
It is pretty sad when the stealership installs a multi thousand dollar engine and lets it leave running worse than when it arrived. Makes you wonder if the problem is deeper than the place replacing garbage with garbage doesn't it?
Someone has not been too bothered about their work. Maybe a Friday job, get away early to the pub, like they do in the UK.
I´m kind confused, why that company have gasoline engines in their citybuses, when modern diesels are more effficient than gasoline, and also last longer (normally), or is it something with emissions in there?
If it`s fuel issue, dont you have winterdiesel there, as we have here in Finland, goes nice down to -30c arcticdiesel even lower.
Anyway that kind of engines should never leave any shop, and even more from dealer, that is not exeptable, rebuild or new.
Groovy! A bus 🙂
Crazy fault on a supposedly new engine! Crappy engine swap by dealer! Superb diagnostic, Ivan! Pressure transducer is an absolute must! Were the cylinder heads properly torqued?
Great job Ivan. You were all over this pig. LOL. I think you might have found a dozen more problems with it if you kept going. They must have gotten these engines out of the junkyard without any verification.
By 'junkyard', I assume you mean Furd HQ right?
The only reason Furd BUILT a V10 was so that there were two 'spare' cylinders right from the outset...
What about exhaust valve worn cam lobes?
Ivan, I'm not a New Ford man, love Chryslers and older Chevy 5.3s,. As far as I am concerned, most newer Fords are design-wise "JUNK". Ford has taken over the mantel of RECALL KING! They really make too much junk today, period! Somebody messed up those engines so the Bus maintenance supervisor needs to get to the bottom of this situation or advise the fleet manager to purchase better vehicles.
