It truly is a “mid engined” masterpiece. I love Johnny Rev. ❤
We love you grand wizard ❤️
Just as much as Johnny car ninja loves BMWs
Aye it’s the wizard!!!
❤❤❤
@@anabolicinsider Just a Car Wizard. Nothing more.
38:00 you called it. The engine was mis-tuned. Oh you didn't quite say it?
No problem bro I did. Cheers 🇨🇦
Tuner screwed it up or the actual re builder of the engine didn't use correct gaskets or ?
@@NoWr2Run Definitely a bad tune - whoever did it messed up the injector timing really badly - if they had it working hard on the dyno like that it could very well have caused the head gasket to fail due to detonation & really pretty lucky that's all it did. Jared is a class act not naming and shaming - I would.
@@Beer_Dad1975 VERY TRUE, TUNE WAS REALLY BAD FROM WHAT HE SHOWED US.

Your Mr Science episodes are great. Diagnostic is such an art... And having an occasional episode on them is very appreciated! Cheers!
Glad you like them!
@@TheQuestionableGarage I love them!! I never know what I could learn from someone, and your videos are all fascinating sir. Can't wait to see Jonny rock!!!
@@kipmcmillan7800 I'll second that and I haven't worked on cars for over a decade or more
A vehicle like Johnny needs an owners like Jared. When even a simple fix can become an adventure and you need someone will to go on adventures to keep them running..
Lol, I see the notification of a new Questionable Garage video and I literally cannot click on the link fast enough 😂
7:39 Both me and my coworker agree that there needs to be patches or stickers for the Engine-Runner-Gooder logo.
I don't know shit about cars but oddly enough Jared does an amazing job at explaining things to someone like me haha
Brilliant video Jared I love the fact you take the time to fully explain what your doing and why your doing it. Honestly you would make an epic teacher and gutted to hear that others poor workmanship put the truck down again. If anything knowing your work it's coming better and meaner.
IR (heat) is an excellent way to diagnose problems. I use a cheapo HF non contact IR device to check that my brakes are working right after I service them. Thermal imaging devices are also very handy for troubleshooting electronics, you can often quickly find the problem by finding the thing that is getting way way too hot
Oh snap that's a great idea, I always just use my fingertips. Bonus is they can't ever connect me to my crimes since I don't have prints. 😂 IR guns are great for checking headers to make sure everything is firing, never thought to check brakes that way.
I use an IR Thermometer to diagnose sticky brake calipers.
It is sooo much better than using your tongue.
@@mikescherrer4923 Exhaust runners if it has them, COP IGN coils, Brakes, fault tracing electrical issues, cooling systems, lots of uses.
And don’t forget breast thermography, finding cancer in boobs.
Even with the time lapse I was impressed how quickly you had those heads off!
TQG is where I will go from now on for all my engine-runner-gooder learnings.
A guy down my street bought a CU Later grey Supra and I pass it twice a day and think about you buying yours! I can’t wait to see it happen man! 🎉
I’m here I’m here for the engine runner gooder certication. 😂
I owe Derek a thank you for introducing you to a lot of us. I've been enjoying the heck out of your videos! You're one cool guy, who is not only funny and very informative, but your positive attitude is infectious! Keep up the great work, Jared, we appreciate it. I need to go buy me some stickers 👍
Welcome aboard!
Jared does a great job at explaining cause and effect (especially on failed parts or systems), which not only teaches logical mechanical/electrical thinking, but also shows you how to cross things off of your trouble list. Johnny Rev makes me want a muscle truck of my own. Great content!
Knew a guy with an old motor home that was smoking bad. He figured the motor was bad so swapped it but it still smoked. Turns out there was something wrong with the brake booster/master cylinder and it was sucking up the brake fluid.
Had a golf GTi many, many years ago with oil in the coolant. Had a head gasket job, but it turned out it was a water/oil heat exchanger all along. A couple of years after my incident, VW sent out a recall notice about it. An expensive bummer all round.
I have also seen people use thermal cameras to diagnose vampiric draws. You look for the fuse thats warmer than the others.
Love that Z32 up above on the lift too
🤔 Jared, If this was a brand new remand engine with very little miles, and heat cycles on it, as you're saying... I think a head gasket in this circumstance on a mild built without boost or anything crazy motor, would have less to do with a tuner and have more to do with a cheap head gasket and improper installation of it. Now, you might be able to afford replacing it and want to do everything properly but I have a "QUETIONABLE" suggestion to try 1st, in this circumstance before ripping into your new motor... I know too late this time. 😬
1. Before you ripped it apart, you could have used a boroscope, to determine what cylinder was having the head gasket cooling leak, without doing the disassembly.
2. Drain the coolant...save it, you know we're doing this on a budget. Reinstall the spark plugs. Then start the engine run it for a minute, and warm it up with no coolant, just don't overeat it. This will dry out all the water passages in the motor. This step of draining the coolant is not necessary, but will help making sure no issues with anymore seepage issues for the next step.
3. With aluminum heads like here make sure motor cools completely down. Now you have found what cylinder is the issue, so now remove everything you need to, to remove the valve cover for that cylinder. Next go through and retort all the headbolts. Back each one off a little bit and retort it to factory spec, one at a time. You may want to do this on both heads. Just to make sure they were torque properly from the beginning. Retorqing heads especially with cheap headbolts and cheap gaskets is sometimes a good idea after a couple heat cycles on a new engine. Most quality gaskets and parts with properly installation, theses days this doesn't have to be done these days but...
4. Reinstall your valve covers, replace gaskets or high temp RTV if necessary, Refill your cooling system if needed. Put everything back together, and then pray 🙏 it worked. If it doesn't work you're going to definitely have to follow the steps here that Jared's doing here unfortunately. Some of you may say this is a waste of time, I say it's worth the try. It has worked for me, and it cost nothing to try just a little time. Note now this will most likely not work, if at all on an older high mileage engine, this is only a segestion for a new engine, like here in this circumstance Jared has.
😉👍 I hope these suggestions helps anyone in the same circumstance here Jared is in with savings and cash, and if anyone has any argument or anything to add to my " QUETIONABLE " suggestions here, please I would love to hear them.
This video has a massive amount of useful information I didn't know before. Especially the spark plug diagnosis. Thanks Jared.
Hot tank, magnaflux/dye heads. Good reason for big valves and a port+polish. Some multi layer gaskets and call it a day...
One of the best thought out, plainly explained, and fully explained diagnostic videos I’ve ever seen. Bravo! Bravo!
The test valve seal, sit the head on some rags block face down, pour mineral spirits in the ports and wait. If there's a sealing issue then the mineral spirits will leak past the valve.
BTW, when you first showed the spark plugs I saw a green tint to the ground strap...I knew right away you had coolant in the combustion chamber. I unfortunately have experienced this enough that it was easy for me to spot.
I love a good Murder mystery. A real “who dun it”. So many clues to unravel, especially the last one “three strikes and you’re out”
I’d take a vacation and spend a week wrenching with you just for the ability to learn. Knowledge is key my friend! Some lessons are more expensive than others. I have a few projects that are all broke myself. Then my daily was totaled by a drug addicted coworker who got caught. But not til running from the police. Good days and bad days!
So glad you and VGG did the econo van otherwise I wouldn't be here lol
I've had one of the FLIR One camera models that plugs into a cell phone. It's a great tool for so many things. Like finding out how your beehives are doing :)
25:26 and a REALLY quick way to see if coolant is getting in to the combustion chamber is to use a borescope camera and inspect the crown (top) of the piston; a cylinder that is firing normally will have a coating of black carbon on the piston crown from the flame front; if the piston crown looks like its has been "steam cleaned" with absolutely no carbon on it, you can guarantee that coolant has been getting into that cylinder and is being burned along with the fuel/air charge.
EDIT: the logo at 7:38 NEEDS to be turned into a Toolbox Sticker on the Bunker Branding Page! (maybe have a whole series dedicated to various systems; since the Engine-Runner-Gooder one is equivalent to Engine Performance, have another for Engine Mechanical, Steering and Suspension, Brakes, HVAC, Electrical, Fabrication, and Driveline)
Cool, not the blown head gaskets, the tuning. I'm really looking forward to that, I'm an old guy so I have very little knowledge in that area.
Great attitude, Jared! It seems luck is an elusive thing for you and things are simply not breaking your way--over and over again. Rod Stewart was right: some guys have all the luck. There must be some great things going on in other aspects of your life, at least I hope so! Keep going with your excellent video content regarding the nuts and bolts of grinding out diagnostic issues. You truly are a master. Don't trust it to anyone else.
here's a good one had an f150 come in from auction was smoking constantly and was apparently losing brake fluid as we brought it into the shop i went and smelled the smoke wasn't oil wasn't antifreeze but come to find out it was break fluid after a taste test! the master cylinder seals were blown and leaking into the brake booster therefore vacuum was sucking brake fluid into the intake.
I bet that cleaned the carbon off the valves.
I have not had a head gasket issue in a couple decades but back then you could smell the coolant in the exhaust vapor. Same with fuel and oil. All three had a distinct smell but I know oil and coolant have been reformulated a couple times in the past 20 years.
Thanks for the info! I've never worked on newer engines, but honestly, it seems like it's still somewhat similar to the old stuff!
Head gaskets, have been my nemesis for years. Always when I'm far from home! 😂
Thanks again Jared
I love g
Fel-pro gaskets, use them all the time. Which is what you have there. However, like you said LS’s use MLS gaskets. All of them do. And that’s what should have gone back onto that deck surface.
I’ve even copper coated many MLS head gaskets for LS’s and re used them in a pinch, never had a single problem. I do believe the main cause of that issue was the head gasket material that was used
I think it was a big part, but in some things not directly covered it had some extra help from the 1s and 0s in the tune
Like you said, just do your own tuning. I definitely do lol
@@johneburke1 I would agree wrong gasket for this application, I'm not saying it's a bad gasket but not what I would have use...
A little extra cash in your building process can save you a lot of headache and more cash later sometimes...
However to try fix and save a little cash in this circumstance with a new motor, with very little heat cycles on it. I would have simply tried to retorque the head... it's worth the shot anyway before having the extra cost to replace headgaskets, just takes a little time to try anyways, and might save you a couple hundred bucks over replacing all of the upper gaskets, maybe...
I don't know tons about LS engines either (though I am learning all I can daily), the early (pre-2000, I believe) had graphite head gaskets.
As a side note, the way to tell if your engine has graphite or MLS head gaskets is to look for a rivet in the little bit of gasket protruding at the corner of the head.
Jared skip the step of pressurizing the system and looking in the cylinder to find the coolant. You can get a kit to pressurize the coolimg system, then use a small borescope (depsteck is like $30) to confirm the leak. This is critical because I almost change a head gasket but it was an EGR cooler leaking.
27:15 I thought you were going to pull the intake through the firewall for a sec. XDXD
I use a Klein 250 infrared camera, works great but the Vevor one looks better so I may give it a go. Here in Central Florida we use them for all kinds of things. Air Conditioning, exhaust, testing for amp draw and more...
Glad you got the truck sorted out.
I feel your frustration. I'm trying to finish up a 70 chevelle and as soon as I fix something, something else breaks. Gotta redo intake manifold gaskets next as soon as I get the time to do it. Lots of diagnostics point to the engine sucking up oil from the lifter valley.
Love the truck that can be driven and enjoyed but not worried about the exterior.
Great video Jared! Kind of heart breaking to see Johnny sick again. Especially since it was a "just one of those things" kind of problem shortly after you had it working so well. I am sure that you will get it working perfectly and that Johnny will go at least 276.35 days before something else breaks. Thank you for the explanations. I think they were top notch.
276.35 days - aka right before a road trip 😂
I’ve never liked buying reman engines. I’ve done it and never had one I didn’t have to break down and found an issue
37:24 moral of the story 😅 find a good tuner that you have vetted and trust or learn for yourself 😅
Once you said the engine is like an air pump, it reminded me of when my grandfather told me that the first time and I was so confused lol, thanks for being awesome Jared!
That sounds so frustrating! I like your attituded of "we will just fix it". Looking forward to the tuning episode!
I would like to see a video explaining what you see wrong with the tune! I understand if you don’t want to tho! That’s fair!
ask Holley for an injected tunnel ram setup to help fill that engine bay.
Super interesting as always Jared! I loved seeing how you sussed out the issue. I can only assume that you won't use those tuners in the future - "Three strikes and you're out" pretty much says it all!
We have TONS of issues with our LQ9's but they're idle related. We've got a fleet of 20 that mostly idle; top speed is 20mph. Head gaskets, cracked heads, oil pump issues, rod bearings, water pump failures, etc etc. We can't get them to last more than 2 years; about 10k hours. Luckily we've got the swaps down to a science. 12-15 hours out and in.
Love Robert from Aging Wheels. Can’t wait to see his 900hp electric suv he’s building 😊
Those synthetic gaskets don't take heat that well they go bad FAST. I had the exact problem on a 91 Passat the heatercore blew drove to the next exit only 2km mostly coasting, Lucky me it was only the headgasket in the end.
Another great Questionable garage university education video
I love the 2nd generation 300zx on the lift. I had a blue one for many years. BTW the rims are directional, the scoop in the rim should face in such a way to remove air from under the car.
Same as the sawblades for the mkiii Supra! Those are just in as rollers so I’m not surprised I got them backwards!
Flir has attachments to fit your phone. The only bad is the one I have, well doesn't have replacement batteries.. that's the downside.
Mine will last a whole 10-15 minutes now, where it should be much longer.
It has helped me find parasitic drains.. they "glow" now.
I need a UA-cam University Certified Engine Runner Gooder sticker for my toolbox.
It would sell like hotcakes
I hope one day I can get on the level of positivity you and Brent are on...I'm trying
Brent is next level! So glad @pfispeed became a friend. Just remember, sometimes in really bad situations the only thing you can control is your attitude.
@@TheQuestionableGarage yea it's good to have people who inspire you to be better. Just wanted you to know you (and Brent) are helping people become better people as well as mechanics.
I am so thankful for your educational videos. Thank you!
That you are not flaming the tuner is striking. You are developing radiance.
You know what always gets me, whenever a UA-camr has an issue directly caused by a certain business, they won't throw them under the bus for it. They always want to dance around the issue and not commit to calling out the b/s for what it is. No negative vibes towards Jared (he's a gem), but people/businesses that do shoddy work really do need to be called out for it.
One of the biggest issues(not directly mine) is the potential to be sued. Even if it’s all 100% factual there is always the chance of litigation and the cost of defending yourself isn’t worth it.
My case, I’m tired of the negative stuff and just don’t want to keep putting that energy out.
@@TheQuestionableGarage Yeah, I completely understand it. I suppose it's really more of a thing over there in the US where someone can sue you for just about anything. Like I said mate, no criticism towards you and I genuinely think you're awesome and do some excellent work. I just really hate to see the bad actors get away with crap like that.
@@TheQuestionableGarage maybe you should sue them.
The best way to determine whether it's oil or coolant is to smell the smoke coming out of the exhaust. You will immediately know.
Awesome as always.Thanks for sharing and taking us along
I got and odd problem with my truck I could use some help and could be very helpful and good learning experience
Hi Jarid !!! Nice truck 🚚 🛻 and garage maybe the pistons were lose 🤔!!! For or maybe it was your brothers new car blue one for the explain of the spark plugs 🔌
Great video. I probably would have put new head gaskets on and adjusted the tune.
The catch can for the PCV should be on the hose that goes to the high vacuum side post throttle body, not the intake tube (low vacuum, if any). Doesn't hurt to have one there either, but it's not as beneficial.
There are so many ways to skin that cat with a ls I’ve learned, the current setup has served really well, so o try to avoid changing it up too much!
Love the educational info. The quality shows I enjoy tell me what I did wrong in the past and have helped me as I move forward turning wrenches. Thank you.
With diesel engines, if the EGR cooler is leaking, that can also make a head gasket tester turn green
Good ol propylene glycol, always gives it away with that smell! sorry Johnny is down for a bit! Great info in this video
Great video, i'm glad you did not shorten and 'dumb' it down.
That red car sure looks interesting. 🐎
Forgot he was going to be working on the Car Wizards 308.
I don't often go to comments because I watch UA-cam on my TV. However, I was hoping the comments would confirm what I thought Jared was referring to at the end. Now I know. Thanks all.
This video is incredibly informative!
I had an internal crack on a SBC 041 head, and it was cheaper to get as cast AFRs vs another set. :P
keep searching for that intro its so nice
Thanks Jared!😊 P.s. I watch all the Ad's for you without skipping 😂
Excellent Vlog…because I’m a hack (at best), when I saw the smoke I immediately thought ‘head gasket’ (bitter experience unfortunately)…
I have decided that I am a lot smarter than I thought. I was about 90 seconds in when I told my wife that truck needs head gaskets.
That's a really cool street truck, can't wait to see more 👍
This is why I work on my own stuff Jared!
jared's gonna go around in the woods hunting the predator!😂😂
Love all the information you are so willing to impart to us. Can't wait for the new car to get started!!
Bummer on the engine issues but excellent tutorial!
Thanks!
The UA-cam university logo needs to be a sticker.
Pretty shure those fiber gaskets leak. Come to think of it they usually fail on exhaust manifolds and collectors. Check the heads check the deck and use MLM head gaskets. Or just copper spray the MLM and slap it back together.
Great video jared. Wouldn't mind seeing you help out with a P1 sometime soon 😉
One great video
Glad you enjoyed it
Good job!
Those gaskets were not sealed. When we run aluminum heads with that type of gasket on iron block we spray an Adhesion promoter on both the aluminum head and the block. I think your leak is from the Gasket material itself and it should have been an MLS gasket.
Great content and useful information
Absolutely llllllllove that International man 😉👍
Do an in-depth on how to tune with like an SCT tuner on the PC?! Pretty please!
Maybe time for a new master cylinder and booster while your there. Big ol fancy engine but a ol rusty master from 1970
those head gaskets where only on the very first sand cast LS heads. They are Much cheaper. look for the V cast near the spark plug holes. cast do not have them. if you do they are a die cast and need MLRS head gasket
I know you do all this for the channel but I really hate that it puts stress on you. You’re the only guy doing all the work. Yes you have a lot of cars to work on. It must be difficult to decide on what to work on. Great video, great work.
Wow, YTU Certified 😂Engine Runner Gooder program.. you need that on a sticker!
Thanks for sharing all your knowledge
What will you do to the surface of the block? Three strikes and you're out. Got it. Very diplomatic of you.
I will pull out my machinist edge and measure it for flatness, after cleaning it with my carbide blade. If it all comes back good, new set of heads, with new head bolts and fresh mls head gaskets!
@@TheQuestionableGarage I can't wait to see how it turns out. I hope you had a great day today. Up late editing videos? It's just past noon here in Korea.
33:34 Every Subaru mechanic just went “Well, THERE’S yer problem!”
Damn graphite covered head gaskets.
Hope the bitey bugs are leaving you alone Jared, great vid
I really love the Patina that vintage US cars get... In the UK, it's just purely rotten thru metal when you see rust... Surface rusting is NOT a thing here. 😂
