The level of detail, amount of knowledge and sheer effort taken to document this process is just amazing. Excellent as always Jafro and thank you for sharing your skills!
***** I couldn't decide where to post this, but thanks Jafro, and you too, Tom (though your jumper has a different name on it...) for your different but great contributions. Thanks to you guys and some others like Eric the car guy, I'm getting much more confident ripping into engines. I'm messing with a Honda H22A4 in a bone-stock 2000 Prelude base model, but the broad similarities between the two 4-cylinder engines have helped quite a lot. I literally used Plastigage for the first time in my life this week, and the tolerances were good!
David Weatherly Thank you David and good luck with your Prelude! I agree that videos like Jafro's and Eric's are extremely helpful as they are fun to watch. Have a good one!
I'm in the process of doing my 1st 4g63 bottom end overhaul. And I've watched these videos at least 3 times. Just wanted to thank you for the detail and effort you went through to document all of this. It's made this a go to source of info for me and many others. That makes these videos timeless. As long as there's still a few DSM's on the road, people will have this resource. Thanks!
Great video. Years back I had a 6 in line Ford engine. Did not have much money so I took everything apart, clean all and then install with new standard rings and new bearings. Took no measurements and ran for 100,000 more miles. I was lucky. You are doing it the correct way.
I am new to this engine building simply because I never really took the time to read or search for information. I've been doing research on completely disassembling and assembling an engine for a month now with my service manual and the web. but coming across your page has motivated me even more to keep learning more. such an educated guy here not to mention Hilarious (26:20)..
So I just wanted to say thank you so much on this series, and everything else related to this engine on your channel, it's really given me a clear idea on my build. I just bought a 1G Talon Tsi AWD for super cheap, and I'm about to pull the engine out for a rebuild. Seeing it all done like you have and seeing specs, part numbers, is probably going to save me days worth of time getting it back on the road. So again, thank you!
+Robert Ballard your replies are disabled. Look closely at the set again. Only half the shells should be grooved on the mains. If you haven't cut the plastic open, it will appear as though all of them are grooved. The groove meets up with the other half of the bearing shell, and the groove extends to the oil holes, but it shouldn't go all the way around. If you've already cut the plastic and looked at all of them, and they are indeed grooved, then I would not use those bearings if the groove is full-circumference. Not on a 4g63 anyway.
Just got back from the Renaissance Festival and camping for four days. Haven't even checked my email yet but I did find you latest video!!!!! Thanks for sharing your time and your knowledge freely, my kind sir.
I can't stop watching your videos, especially since I'm laid off until march! Your getting a % of my NJ unemployment check. Thank you for everything you do!
Three 'Sloppy Mechanics' references and a leaky 'o-ring' joke as you were checking loose rings; I am left in awe after every one of your videos Jafro, thank you.
I'm just impressed that some checked the description. You'd be shocked how many people don't bother reading it or click the "Show more" text to see everything. 16 hours is crazy! haha. A 12 Core Mac Pro with Hyper Threading (24 virtual cores) would chew this footage up and spit it out. But that's 10 Grand for a maxed out model. I wish you had lived closed to St Louis where my car broke down and still is... I would of gladly paid you whatever you asked for, to fix my car. :)
And for you I think I might have been willing to do it. :) But you still wouldn't have it back. :( Did your make and model have an interference engine? Edit: I'm rolling with 16 2.4GHz virtual cores rignt now. My how obsolescence occurs quickly.
***** yup. IT was a dual overhead cam engine and it was in fact an interference engine. He's got it running and everything now. Just gotta give him 2 grand plus the additional fee to replace an oxygen sensor that went bad right before it died. We'll head up there Monday.
***** I personally wouldn't want the new Mac pro nobody likes there computer to look like a trash can lol not been impressed with there bad for the earth book pro you can't even replace the battery when the battery dies it will be trash,I like the PowerPC era of apple
Until you've used one... man... you have no idea. It reads and writes a gigabyte a second. Nothing else in the consumer market is keeping pace with that right now. Nothing. It could be in a plastic Hello Kitty enclosure and I'd still want one at home. It's astonishingly fast.
always need more power, think ridiculous like dual $3000 intel xeon 12 core server CPUs with over 256gb of RAM, 4 way SLI GTX 780 TI graphics... and linux for the maximum efficiency. hackintosh or a virtual machine if necessary. that kind of money grows on trees right? . i have always used (2 stroke)premix for assembling jugs and slugs, it's designed to be in a combustion chamber and it smells great. the ending was great Jafro
I really like the way you describe everything you do while I see the footage. All the details, specs, and instructions are great and not getting me lost. Keep up the good work I'm always watching your videos and waiting for more!
Wow. The work you do in putting these videos up is astonishing. Thanks for all the hard work. I would rather see one well done video every month or two than a crappy, slapped together with little to no thought every other day. quality over quantity.
the amount of information in every single video you make is just mindblowing. If only we could slow down the actual video and watch the whole process in normal speed.....it would be the perfect education source
My head is pulsing and all I can think of is that I have to clean my key with an air compressor before I put it in the ignition out of fear that dirt will work its way to the engine :/
Since I got those billet main caps and main girdle. I'm finally gonna be setting up the painfully long process of align boring. But it will be fun and a learning experience.
Thank you for another great video! I celebrated with a yell and hands in the air when I saw it was 40 minutes long! Keep up the good work, spring is almost here!!
Awesome video, thank you for the work you put into these. I especially like the comparisons you make from your application to a daily driver application, explanations like that go a long way on the "why?" side of things.
Glad to see something from you. Its nice to have some entertainment. Just got back to some internet so I have been in the dark ages for a few weeks. I expected nothing more for the Hyundai and since its getting warm out, I expect to see some good passes with the Hyundai soon. Robert
You're an easy builder for real that blesses me thank you so much it's been a long time I need the refresher course I have a new crank new bearings into the machine shop they said the cylinders are good I have new Hastings cast-iron rings I wish I would've kept the rings that were in it because I can see now that the law and went out in a Kia Hyundai 2.4
I bought that same torque wrench when snap-on first started offering them and instantly regretted it. The following week I bought the flip dial mechanical ones and never had a problem again. Allegedly they came out with a version 2 that didn't go through batteries like a champ but I was too skeptical to try.
See all those wee holes in the piston oil ring grooves? Those are there to allow oil scraped by the rings to flow back down into the motor. Why point this out? Well, I happen to own a 1.9L Saturn, and like all 1.9 Saturns, it burns a ton of oil. That's because Saturn didn't bother to add those wee little oil ring drain holes in their pistons. Therefore, if you fail to use a good synthetic oil that can resist high heat AND change the oil often enough on a Saturn, the groove will fill with baked carbon crust, seizing the ring and preventing it from doing its job. But, if you treat your Saturn like a two stroke and top the oil off constantly, it'll happily go to 300,000mi. That's also why Craigslist is littered with Saturns that have engine issues; someone let the poor thing run down to 0qts. Prime candidates for Chumpcar or LeMons! Now you're a Saturn expert. Tell your friends.
I follow you from Italy Your work and just perfect and the way you explain if you were my teacher in school would become mechanic I look often Roadkill hotrod thanks for having awakened my old passion
Woooaaahhh just got me saying, I need to study further before I start overhauling and replacing parts of my Hyundai kappa 1.4 MPI gas engine. I have been doing study and research on putting turbo on this engine. No worries blowing it but to do it the right way is important to me.
Awesome video, I love your attention for detail. I am curious how much difference it makes when you just build it up without paying attention to these details. But that's not the point of course, it's just great that you love your work so much.
+s0012823 It's the difference between knowing you can pound on it, and not knowing what it's going to do? Worst case scenario is you get an oil clearance wrong and munch the engine shortly after cranking it. This is all stuff you absolutely have to do. Now you know how. ;)
Thank you, that was brilliant :-)) So many things to think about, and you have nicely balanced values. Not sure if i beleive the chair made that noise ha ha :-)) Ive never touched anything complex, just two and fourstroke motorbike engines, the very basic checks have kept me on the side of luck :-)
Again, always a joy to watch, but if I could get your opinion about the rings for final assembly of the rotating assembly. An old colleague of mine who used to build motorcycle engines argued the fact of the piston ring gaps being put in line with the next ring below it and so forth. Our shop teacher said this would affect piston gas blow by into the crank case and so the correct method in his opinion was to stagger them so the would not line up stopping the gas blow by. My friend said that was wrong because the staggered rings would wear the bore unevenly, and had better results with lining up the gaps of the rings in final assembly. I am really on the fence with this so what is your idea on the subject. Lining up or staggering the rings. Again, a amazing video to watch.
The rings should be staggered. The way I did this is exactly by the recommendation in the service manual. The gaps are 180° out-of-phase, and all of them land on the 45°s because that's where they'll do the least damage to cylinder walls. If you line 'em up on the pins or the thrust surfaces, you'll cause a problem wear-wise. If you line them up, you'll increase the blow-by substantially. This car already has such loose rings that I would probably be lucky just to get it to fire on first startup if I did that. The real way to prevent wear is not to leave sharp edges on the rings when filing them. If you de-bur the edges and stack them the way the service manual has them arranged, you'll get the best compression numbers. Compression is key to making power.
This is awesome. I'm about to have a go at blue printing my own RB25DET. Great learning tool. No it won't be my 1st rodeo, but it will be my 1st one producing over 650 Crank HP so precision is key.
I've just used a grinder on my crank girdle to enable the front axel to fit through the sump on my rb25det, I used shaving foam to help retain the grindings, I washed the block out with brake cleaner after too. looks like it will be junk now having seen just how clean everything should be...
08:50 The Service Manual doesn't care in which order you loosen the main cap bolts, but I think it's odd you start at the center and spiral out. Starting on the outside and spiraling in (like head bolts on page 9-54 and 9-39) makes more sense to me.
I've always found the shortblock assembly was the most stressfull. It can make or break your engine. So like you I get rediculously clean with my parts and get all OCD checking my work 2-3 times. Once my shortblock is built it's like a weight off my shoulders and the rest of the engine just bolt on stuff.
Do ARP rod bolts, and ARP Main bolts benefit stock 6 bolt internals enough for the cost? I have all ARP bolts for my bottom end on my stock 6 Bolt internals (it came with the engine when I bought it). I'm seriously considering putting the engine back together with those parts; as opposed to waiting to save for an all forged rotating assembly. Aside from specs for torquing them down, and proper ARP assembly lube to install them. Is there anything I should look out for while assembling my 6 Bolt with those ARP components? I am going to prime the oil pump with Vaseline, and use Royal purple assembly lube for the rest of the assembly process. I took a page out of your book, and I am going to use Evo 8 rockers, mine are fine but I just want to put those in because they seem to be quite a bit more stout; and new lifters since mine have the microscopic oil holes on them and new E/I valves. I have different than stock exhaust valves, I'm having a hard time finding out who made them. Any advice on how to possibly identify them? Any and all advice is greatly appreciated.
Newbie question. Why not use new rings if the bore hasn’t been honed/bored? I’m working on an older BMW 4cyl and upon disassembly the rings were completely stuck with carbon buildup. The bores and pistons are in spec and therefore I was thinking of using them with new rings.
I have a 2003 Hyundai Elantra GLS with 95k on it, but its a automatic. I would like to upgrade the transmission and engine , but I'm such a beginner under the hood but willing to learn. And help??
Have you ever used one of those Wiseco Tapered Ring Compressors before? It can be expensive, because you have to buy one for each size bore you're dealing with. But the pistons go in like butter, using only 1 finger.
I just checked the way you did here And my block is warped 4 thou Do you think it needs to be machined I'm gonna try a felpro graphite hg Do you think it will hold it it
Hello, I am building a hybrid motor with 4g63 head on a 4g64 wideblock from a truck. The pistons are wiseco, 4g63t rods and the required crank of the two blocks to fit. I had a shop inspect and assemble block some years ago and now I am trying to finish up the build but was told I need to disassemble the block again to have it balanced with my lightweight competition flywheel and clutch set. Is this balancing necessary on this hybrid build in your opinion? thanks... i am running no balance shaft also.
Hey Jafro. I'm trying to find the video where you use the tensioner arm #MN119896 as a replacement for the discontinued 6bolt tensioner arm MD130032 but I can't find it. Please help me out as one of my buddies doesn't believe it and I want to show him. Thanks for all your wisdom bud!!
Once again watching this video, and I'm trying to figure out what crankshaft refurbishing video you were referring to. Were you referring to the knife-edged crank video? Where did this crank you're using come from? I'm easily confused.
My script for the voiceover is 6 times longer than the whole script for the movie Pootie Tang. 6 times. Longer. Probably the best thing ive read in along time
I have hundayi accent 2011 model new shape, and needs repair on head gasket, i want to do conplete overhauling of engine, do you have detail Drawings/blueprint links or websites to do so?
You should be taking FOUR measurments per journal. Two measurements 180 degrees apart at "both ends" of each journal. That's how you determine out of round or "egg" as you call it and taper. Same goes for cylinder bores.
+Colin Smith They don't move much. You orient them this way to achieve maximum compression while the rings set on first startup. You want just as much compression and vacuum as you can get. The way they're turned against eachother ensures that the path of least resistance is as long and complicated as possible.
Could you take the measurements on the bearing journals with a digital caliper as opposed to Micrometers? If so, would it be adequate enough to trust it's readings? If you can't get your hands on the tools you used, would using a digital caliper be a viable option?
+BoostedCajun Nope, nope and nope. Digital calipers' results should always be treated as a guess. They actually have no place in precision machine work. They're a handy tool for anyone who can formulate the answer they need off of a rough estimate, but just can't be trusted on measurements like oil clearances or piston to cylinder wall clearances. In that regard, plastigauge actually works better. With engine assembly, it's calibrated micrometers and precision dial gauges-only, and all parts and tools must be room temperature.
+Jafromobile good to know, I found a digital pair of micrometers and have read reviews of them and will deploy them once I have my rods, and new pistons ordered. Glad you go into such great detail on these videos. Below is a link to the micrometer set I will be buying for my up and coming build. www.amazon.com/iGaging-Digital-Electronic-Outside-Micrometer/dp/B00KY2PG12/ref=pd_sim_sbs_469_2?ie=UTF8&dpID=511UilpurKL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=1PTF2FGZS8N8VCGH3H30#customerReviews
Jafro, do you have to get the rings bang on specs or aim for around the spec? if not, how much off are you allowed to be off; 0.0005? more? One of my rings gives a little drag on the feeler gauge but another it slips right in but the next size up will not without moving the ring so I guess it is in the middle, is that ok or have I taken one too far? Thanks!
When inspecting main bearing clearances...other than the fact you mentioned it is covered in the FSM. Is there any reason you are using plastigauge rather than a bore gauge? I figured I would use a bore gauge on mine and do the math to figure out clearances like you covered in your Blueprint 100 series. Thanks Jafro.
Hi Jafromobile.. Awesome job.. Clear explanations.. Would you be kind to tell me what's product's name on 35:23 ? Does it unseized engines?.. Thank you.. Portugal..
Amazing how fast and right to point you answered it.. You're a big PLUS in this world Jafromobile.. We all benefit from your teachings.. And it's free ;-) Really, really appreciated.. Take care..
HOLA, ME PUEDES AYUDAR CON LA INSTALACIÓN DE LAS MANGUERAS DE VACIÓ, LAS QUE ESTÁN EN EL SISTEMA DE INYECCIÓN, NO PUEDO PASAR GASES Y CREO QUE COLOQUE MAL LAS MANGUERAS. GRACIAS
I been working on cars since a teen and just now getting into building engines. I need a caliper capable of one ten-thousandths (I think the machine shop term is tenth?) But all I seen have the readout to do those measurements but accuracy is still only +/- one thou. I can't read/too lazy to read mics, unless they make those in digital , or I'm I stuck with mics as my only tool to measure bearing sizes eta?
Calipers aren't accurate enough in the 10 thousandths to trust for measuring oil clearances. They make 'em that fine, and you can probably find a few different kinds at MSC tools online, but look at what they cost. Compare them to the cost of the mics in the size ranges you need. Once you're done with that, consider their accuracy and which one's a better deal. To get one that measures ten thousandths, look for one that's graduated in .00005 increments.

I am curious how much difference it makes when you just build it up without paying attention to these details.
But that's not the point of course, it's just great that you love your work so much.
+s0012823 It's the difference between knowing you can pound on it, and not knowing what it's going to do? Worst case scenario is you get an oil clearance wrong and munch the engine shortly after cranking it. This is all stuff you absolutely have to do. Now you know how. ;)
Thank you, that was brilliant :-))
So many things to think about, and you have nicely balanced values.
Not sure if i beleive the chair made that noise ha ha :-))
Ive never touched anything complex, just two and fourstroke motorbike engines, the very basic checks have kept me on the side of luck :-)
Still one of my favorite videos on the tube.
Again, always a joy to watch, but if I could get your opinion about the rings for final assembly of the rotating assembly. An old colleague of mine who used to build motorcycle engines argued the fact of the piston ring gaps being put in line with the next ring below it and so forth. Our shop teacher said this would affect piston gas blow by into the crank case and so the correct method in his opinion was to stagger them so the would not line up stopping the gas blow by. My friend said that was wrong because the staggered rings would wear the bore unevenly, and had better results with lining up the gaps of the rings in final assembly. I am really on the fence with this so what is your idea on the subject. Lining up or staggering the rings. Again, a amazing video to watch.
The rings should be staggered. The way I did this is exactly by the recommendation in the service manual. The gaps are 180° out-of-phase, and all of them land on the 45°s because that's where they'll do the least damage to cylinder walls. If you line 'em up on the pins or the thrust surfaces, you'll cause a problem wear-wise. If you line them up, you'll increase the blow-by substantially. This car already has such loose rings that I would probably be lucky just to get it to fire on first startup if I did that. The real way to prevent wear is not to leave sharp edges on the rings when filing them. If you de-bur the edges and stack them the way the service manual has them arranged, you'll get the best compression numbers. Compression is key to making power.
This is awesome. I'm about to have a go at blue printing my own RB25DET. Great learning tool. No it won't be my 1st rodeo, but it will be my 1st one producing over 650 Crank HP so precision is key.
i dont know much about the detailed internals on engine parts, but this really helped even though i drive a "murricamobile" aka a mustang
"You can just throw that right out the window in my case, this thing has been Ron Jermeied..." bahahahah! So glad I found this channel!
is this guy......king of everything ...about engine..
I've just used a grinder on my crank girdle to enable the front axel to fit through the sump on my rb25det, I used shaving foam to help retain the grindings, I washed the block out with brake cleaner after too. looks like it will be junk now having seen just how clean everything should be...
Jafromobile, I just discovered your channel!, thank you for the videos, there are very detailed! Congrats!
08:50 The Service Manual doesn't care in which order you loosen the main cap bolts, but I think it's odd you start at the center and spiral out. Starting on the outside and spiraling in (like head bolts on page 9-54 and 9-39) makes more sense to me.
1:01 Had this crank in the fridge leftover from the bbq cookout last weekend.
This is a professional work, literally...
The engine or the video? :P
I've always found the shortblock assembly was the most stressfull. It can make or break your engine. So like you I get rediculously clean with my parts and get all OCD checking my work 2-3 times. Once my shortblock is built it's like a weight off my shoulders and the rest of the engine just bolt on stuff.
Do ARP rod bolts, and ARP Main bolts benefit stock 6 bolt internals enough for the cost? I have all ARP bolts for my bottom end on my stock 6 Bolt internals (it came with the engine when I bought it). I'm seriously considering putting the engine back together with those parts; as opposed to waiting to save for an all forged rotating assembly. Aside from specs for torquing them down, and proper ARP assembly lube to install them. Is there anything I should look out for while assembling my 6 Bolt with those ARP components? I am going to prime the oil pump with Vaseline, and use Royal purple assembly lube for the rest of the assembly process. I took a page out of your book, and I am going to use Evo 8 rockers, mine are fine but I just want to put those in because they seem to be quite a bit more stout; and new lifters since mine have the microscopic oil holes on them and new E/I valves. I have different than stock exhaust valves, I'm having a hard time finding out who made them. Any advice on how to possibly identify them? Any and all advice is greatly appreciated.
Newbie question. Why not use new rings if the bore hasn’t been honed/bored? I’m working on an older BMW 4cyl and upon disassembly the rings were completely stuck with carbon buildup. The bores and pistons are in spec and therefore I was thinking of using them with new rings.
Great show watch it every day have quick question.I have 2011 2.4 need to rebuild it were would be the best place to buy engine parts
I have a 2003 Hyundai Elantra GLS with 95k on it, but its a automatic. I would like to upgrade the transmission and engine , but I'm such a beginner under the hood but willing to learn. And help??
Just amazing .....very good job
Anyone know where to get the spreadsheet at 40:15?
Have you ever used one of those Wiseco Tapered Ring Compressors before? It can be expensive, because you have to buy one for each size bore you're dealing with. But the pistons go in like butter, using only 1 finger.
Hi. Can you tell mi if it is acceptable to replace the pistons rings without cylinder grinding?
I just checked the way you did here
And my block is warped 4 thou
Do you think it needs to be machined
I'm gonna try a felpro graphite hg
Do you think it will hold it it
Because Jafromobile told me to use mayo as a assembly lube!
is the chart a program that you input the data? what is it's name please?
Hello, I am building a hybrid motor with 4g63 head on a 4g64 wideblock from a truck. The pistons are wiseco, 4g63t rods and the required crank of the two blocks to fit. I had a shop inspect and assemble block some years ago and now I am trying to finish up the build but was told I need to disassemble the block again to have it balanced with my lightweight competition flywheel and clutch set. Is this balancing necessary on this hybrid build in your opinion? thanks...
i am running no balance shaft also.

Crankshaft bearing cap and connecting rod cap how much torque apply
I got a 2006 tib 2.0 engine how hard and different will be on swap to a tib gt v6 engine ???
Is it possible to avail repair manuals of audi and bmw....if so then from where can we get them?
Excellent detail explainations, perfect work.
Your best work yet!
Hey Jafro. I'm trying to find the video where you use the tensioner arm #MN119896 as a replacement for the discontinued 6bolt tensioner arm MD130032 but I can't find it. Please help me out as one of my buddies doesn't believe it and I want to show him. Thanks for all your wisdom bud!!
Another great video. Thanks *****
Christopher Bowley ههههههخههههه اخذني وياك
Have u ever done a sohc to dohc swap on a wide block 4g64
Very detail......good work mate.
Once again watching this video, and I'm trying to figure out what crankshaft refurbishing video you were referring to. Were you referring to the knife-edged crank video? Where did this crank you're using come from? I'm easily confused.
My script for the voiceover is 6 times longer than the whole script for the movie Pootie Tang. 6 times. Longer.
Probably the best thing ive read in along time
What is the Hyundai iload, first, second, and third piston ring gap please?
my rod bearings gap is .001 with Acl race bearings and stick internals, is this okay?
I have hundayi accent 2011 model new shape, and needs repair on head gasket, i want to do conplete overhauling of engine, do you have detail Drawings/blueprint links or websites to do so?
You should be taking FOUR measurments per journal. Two measurements 180 degrees apart at "both ends" of each journal. That's how you determine out of round or "egg" as you call it and taper. Same goes for cylinder bores.
This was awesome, the only thing that wasnt correct was spacing the ring gaps.
They rotate around the piston in operation, so why orientate them?
+Colin Smith They don't move much. You orient them this way to achieve maximum compression while the rings set on first startup. You want just as much compression and vacuum as you can get. The way they're turned against eachother ensures that the path of least resistance is as long and complicated as possible.
if the crank isnt spinning how can i fix it whats the solution to this please my crank isnt spinning?
Could you take the measurements on the bearing journals with a digital caliper as opposed to Micrometers? If so, would it be adequate enough to trust it's readings? If you can't get your hands on the tools you used, would using a digital caliper be a viable option?
+BoostedCajun Nope, nope and nope. Digital calipers' results should always be treated as a guess. They actually have no place in precision machine work. They're a handy tool for anyone who can formulate the answer they need off of a rough estimate, but just can't be trusted on measurements like oil clearances or piston to cylinder wall clearances. In that regard, plastigauge actually works better. With engine assembly, it's calibrated micrometers and precision dial gauges-only, and all parts and tools must be room temperature.
+Jafromobile good to know, I found a digital pair of micrometers and have read reviews of them and will deploy them once I have my rods, and new pistons ordered. Glad you go into such great detail on these videos. Below is a link to the micrometer set I will be buying for my up and coming build.

Jafro, do you have to get the rings bang on specs or aim for around the spec? if not, how much off are you allowed to be off; 0.0005? more? One of my rings gives a little drag on the feeler gauge but another it slips right in but the next size up will not without moving the ring so I guess it is in the middle, is that ok or have I taken one too far? Thanks!
Caution! Beware of ring groove scrapers. The smallest deviation or even a dull blade will turn your piston into a paper weight.
When inspecting main bearing clearances...other than the fact you mentioned it is covered in the FSM. Is there any reason you are using plastigauge rather than a bore gauge?
I figured I would use a bore gauge on mine and do the math to figure out clearances like you covered in your Blueprint 100 series.
Thanks Jafro.
Hi Jafromobile.. Awesome job.. Clear explanations.. Would you be kind to tell me what's product's name on 35:23 ? Does it unseized engines?.. Thank you.. Portugal..
+JJAAYY 2 It's called Aero-Kroil, and yes. Another product that will do that is Marvel Mystery Oil.
Amazing how fast and right to point you answered it.. You're a big PLUS in this world Jafromobile.. We all benefit from your teachings.. And it's free ;-) Really, really appreciated.. Take care..
+JJAAYY 2 :) /watch?v=thBelhTmsxo
+Jafromobile I just did watch the 2 minutes video you suggested.. I'll try it in my own old car.. Thanks again bro.. You rock..
HOLA, ME PUEDES AYUDAR CON LA INSTALACIÓN DE LAS MANGUERAS DE VACIÓ, LAS QUE ESTÁN EN EL SISTEMA DE INYECCIÓN, NO PUEDO PASAR GASES Y CREO QUE COLOQUE MAL LAS MANGUERAS. GRACIAS
looks like you know what doing sir!! good video
Now if the clearance on the rod bearings came out of spec, couldn't I try using another bearing to put it in range of spec?
Forget it lolz, you answered it Thumbs up bro
I been working on cars since a teen and just now getting into building engines. I need a caliper capable of one ten-thousandths (I think the machine shop term is tenth?) But all I seen have the readout to do those measurements but accuracy is still only +/- one thou. I can't read/too lazy to read mics, unless they make those in digital , or I'm I stuck with mics as my only tool to measure bearing sizes eta?
Calipers aren't accurate enough in the 10 thousandths to trust for measuring oil clearances. They make 'em that fine, and you can probably find a few different kinds at MSC tools online, but look at what they cost. Compare them to the cost of the mics in the size ranges you need. Once you're done with that, consider their accuracy and which one's a better deal. To get one that measures ten thousandths, look for one that's graduated in .00005 increments.
Thanks a lot man. What's the "cheapest" brand mics would you suggest? Obviously harbor freight is out of the question lol
