For someone that supposed to know cars knows the corvettes whole drive train to back wheels to front wheels needs to drop as one unit including exhaust removing 8-12 body bolts They are a tunnel transmission This makes corvette so interchangeable How did you not know that

My brother and I would watch your videos and message each other when a new one comes out so the other could watch it. He passed away unexpectedly last week and I miss him a lot. Now I get sad when a new video comes out but it is bitter sweet because it reminds me of him. Thank you for helping me remember him! I enjoy all your videos.

After 55 years in the auto and truck fields I have never seen a burn like THAT!!!!

You got the dipstick out without no damage . 2 torched heads was the price of that miracle . The GM Gods work in mysterious ways .

with each upload this editing just gets better and better

As someone who has pulled heads from a C4 before, I felt your pain quite intimately when it came time for that exhaust to be removed. Excellent video!

Unusual space to burn a head through. Never seen that before. Pistons should have been torched first. Aluminum heads can be welded, but these aren't that hard to find and the aftermarket has better if you went that route.

If you were ever wondering why some things cost sooo much to repair…here’s your answer.

Dude, I’m genuinely impressed with your ambition. To go from rebuilding a Porsche to a Corvette..... just Awesome.

That block's deck still might be worth checking with a straight edge on those hot spots. Even so, that's crazy!

This channel keeps getting more and more entertaining, man. Your content is fantastic. Keep it up. One of my favorite automotive channels these days!

It boggles my age-addled mind that you can remember where all the nuts and bolts go when you put these cars or engines back together somewhere down the road. Glad you got new heads for this engine, although I am somewhat disappointed that the dipstick gave up with such little fight.

Absolutely amazing that the block wasn't damaged.

I just wanted to say thank you. My wife and I've been watching you since you started this channel and we always enjoy it, you're funny you're clean and I get to learn a lot. Especially the vehicles and engines I don't want to buy. Go Ford!!!

After tens of thousands of cars through our shop in almost 40 years, I've never seen something like that on both sides. I'd guess lean running, not bad gas. Maybe a vacuum leak.

I think that was a regular HG failure to start with, but someone kept driving it hard and what you are seeing is the erosion of the cylinder head by the combustion gasses.

I try to watch all of your videos. Not once have I read some one bad mouthing your business. If I need an engine I would not hesitate to buy from you. Carl

That's some wild blow out. I've seen some perplexing things under warranty, but nothing even close to that.

these vids are my favorite way to relax after a 14 hour shift with a cold one 🤘🏾. you sir are awesome keep making great videos!

I am surprised the pistons tops didn't take more damage, they look great!

I'm supposed to be doing homework, emails, and looking for work post-graduation. Video gets posted, all that stuff can happen later 😎

I have an entire LTI engine short block and heads in my garage that I tore down completely to make a 383 for my 1995 Z28. Then 2008 housing crash, and job market went to crap, and I sold the car to make bills. Still have the block and heads, tore down sitting in a corner of my garage.

A mid week tear down and loosening the manifold with supreme editing that takes me back to middle school… it almost feels like my birthday!! 🎉😂

Cooked the heads but saved the engine, and someone sent you new heads! I call that a win-win! Hope there are no more big surprises with this vehicle.

Man, I was so pumped I I thought this was part two of this c four corvette project! I want to see what ends up happening to this car so bad it is one of my absolute dream cars

I'm really fascinated by this head damage. It looks like highly concentrated heat, like a plasma cutter focused right at those two spots. The rocker chambers look pretty clean though, not like heads from an engine subjected to long term high temperature abuse. This damage probably occurred over a short period of extreme use, some relatively abnormal event for this vehicle, a high speed police chase would be believable. If I recall, the '95 Corvette used an early OBDII, or OBD1 Enhanced, engine control strategy. It came out during the transition so it's not impossible to think the program may have been less than optimized. Under extreme operating conditions it may have been running some way out of bounds timing and AFR parameters. It would be interesting to know what secrets the ECM holds. The damage is low in the head's installed position, so if the engine were low on coolant, the high side of the combustion chamber, on the opposite side, would be the first subjected to untransferred heat. The effect would be mooted however if the coolant left the system all at once, like if the bottom of the radiator were ripped out and the engine continued to be run at high speed. Curiously, the damage is toward the center of the block, not furthest away from the water pump and radiator outlet, like the #7 and 8 cylinders would be. Here again, if the system had no coolant at all the center of the engine is where heat would concentrate. Also, the center of these heads is where two exhaust chambers come together, again, more concentrated heat. That all seems consistent with identical damage occurring on both heads, in the same location, at the same cylinder positions, 5 and 6. Combustion chambers #3 and 4 probably weren't far behind for the same damage. Aluminum liquifies from its solid state pretty fast, just a few degrees is all takes to go from soft to molten. It also conducts heat very rapidly, and in response to heat, it expands a lot. All of this would come into play during a brief period of extreme high temperature operation. Also, abnormally high temperatures would have excessively expanded the heads exerting high tensile pressures on the bolts and spot faced bolt perches. Once cooled and contracted that would have left less yield pressure allowing the bolts to break free more easily during disassembly then if they had been at their specified torque/pressure. We saw evidence of that. The failure does not seem to be at the thinnest part of the casting, but does seem to be along the most direct route from the combustion chamber to the exterior of the engine. The escaping heat did not deflect and dissipate into the water jacket, it continued on through the next layer of casting ejecting out the exterior of the head. That means the hot gas jet first blew out the bottom of the combustion chamber into the steam port, then focused on the exterior wall until it blew that out, and finally had an escape path to the outside. Wow, crazy sequence of events! Would love to have had an inside view of that happening... In all it seems like specific mechanical design features, extreme engine operation, a highly compromised cooling system, and possibly unoptimized engine control, all conspired to produce this really weird material failure. For sure I've never seen anything like it, but way cool to see and consider. Thanks Eric, this one's a real hoot.

Man, in the 21 years between when my '73 was built and this '94 they sure managed to cram a whole lot more stuff into the engine bay!

14:11 If I could move my hand that fast, I'd never leave the house.

made my back hurt just watching !!

My 94 Trans Am I bought new has 337.000 miles on it now. LT1 engine, never been touched, even the timing chain is original. Still runs like new.

LOL - The sound of a socket or wrench clanging as is disappears into the harness/bracket void. Waiting to hear that 'hit the ground' sound is the longest 1.5 seconds of your life.

What makes your videos fun is that you are doing the work. I've seen a ton of C4 videos and the person only explains the process. You're doing the work and talking us thru the process. It looks complex till an expert. Shows us it can be done. I'm grateful for your channel and knowledge. (:

A mid week tear down! What will Eric give us next? I've never seen the kid of damage that this car had. Good luck.

Didn't need the "Safety Tote" even once!

I really like the super-accelerated wrenching and the accompanying sound of that.

That’s why I love pre 80’s cars none of the bs… so simple to work on

That's a really interesting teardown! Thanks, as always!

Great to see the engine taken apart while on the car instead of outside, shows how difficult it is!

Nice work, I have a c4 as well and it is tight for space under the hood, strange damage to the heads thought! Strip down the trashed heads and save some of those valve train parts.

These videos are getting so good 👍 easy to follow but gets to the point of what's going on

I can admit when i did head gaskets on my old 5.7L vortec suburban it took me two frustrating days to get the dipstick tube back in there.

You took something apart mid-week, Your the man. I haven't a clue what the original problem is, but it must have been running like shit. And didn't happen at idle.

If you got that car after it was totaled by the insurance company they probably blue them holes in the heads the outer hole is to round like a torch tip having been a mechanic for over 40 years I have seen this done several times

Love your videos, from the mid week updates about your projects that is you just fiddling wit stuff to the weekend teardowns of the engines, I don't care if I've seen the same engine type if the failure is different, heck even just the quality of core is interesting to watch, keep it up

Thanks for an educational tear down, you are the MAN !

Weekly project updates! Wonderful news! Thank you!

Love seeing a skilled person! I really like your tear downs, not at least that you understand how to dose timelapse so nice. Thanks a lot for hours of entertainment!

Started watching this channel last week from an engine teardown video that was in my recommended videos feed. I was pleasantly surprised to see some C4 content. I have an 85 I bought for pretty cheap in 2020. These cars are a blast. Tons of parts out there, lots of fun projects to take on and they really aren't too bad to work on considering how capable they are and how realtively cheap they are.

sounds like a great bit of luck eric and i am tipping my cap to jeff for setting you up with a good set of heads, thanks to you both for keeping another rocket on the road

Each video is so amazing, you’d make a great teacher

Thanks for the update video on the car, take care of yourself and family and be Blessed ❤️👍✅.

I always learn something from these, Thanks!

So glad to see I’m not the only guy who drops wrenches!

Thank you man! I am an idiot. I have been watching this channel for some time and it never occurred to me that I had not subscribed yet. I watch so frequently that YT always recommends your videos as soon as they come out, just like if was subscribed. Anyway, I have now corrected my mistake and subbed officially. You really are good at this, the car part and the being on YT part. Thanks for all your work. It'll be fun to watch when you hit 1M subs!

A very good machine shop can save them aluminum heads. I have seen this a lot on boosted engines. Once you get it back together. Have the tune on the ecu checked (Or Prom) that is a really bad lean spot in the map.

Thank you brother from the bottom of my heart. You inspire me to learn more about engines and all their parts. Im saving up for an lt1 firebird and watching your videos on the ls1 and lt1 breakdowns always peak my interest. I learn so much from watching your vids, great shit man

After watching your fun with this car I'm never going to look at a corvette with envy again. Your patience is infinite.

I had a '94 LT1 six speed that I sold a year ago with 51,000 miles on it. Loved it. Did replace the ignition behind the water pump, installed a factory CD player and a few other mods. Enjoying this video!

I love your videos, and you helped inspire me to start recording my work and post it on KZfaq. Keep up the amazing work!

You know, I work on my own cars, a '14 Cayman S and an '01 Subaru Outback LL Bean, and for 19 years I drove and worked on an '85 Porsche 928S2 5 speed. I'm an amatuer driveway mechanic, but it sure seems to me that it would just be easier to drop this engine and work on it on a stand.

Serious damage to the heads very very impressive! Happy to hear you found a pair of heads to install, look forward to the next update Eric!

Eric you are a Legend for saving cars from the scrapheap. You get the job done with humour and style. Your friend from Australia Tim.

I just remove, rebuilt and reinstalled a 2006 C6 corvette motor without a hoist. It made me smile watching you, it was/is a tough job. I think the C6 was easier than the c4 and I thought the c6 was tough. Good job.

Thanks as alwasys for your great content it was nice seeing you disassemble an engine while it was still in the car like most of us have to do. i love how relatable you are and the great way you know when to fast forward and when to let it roll. Love your channel thanks for all you do.

I found, when working on vettes or ETypes taking the front tires off makes it easier. Whe you get older working leaning that far over plays havoc with your low back.

love watching you tear stuff down!

I'm so glad I flipped the 92 Vette I bought to part out after watching this video . Extremely awesome video as you have more patience than I would have had . After just a very few minutes of looking at what it would have taken for me to do what you did I saw that " I ain't even gonna try to part this car out " . Great video sir

Nothing is easy to work on, on a corvette, I’m doing all 8 body mounts, without removing the body, on my wife’s c3 this weekend. Even the rear end pinion seal replacement, was no fun!!! Great video, I feel your pain, and also your passion! It’s why we do cars!!! Great video as always!!

Nice job, and hopefully everything works out well... I don't envy anyone working on this new stuff... Well done as always

I like the regular updates. I'd like to see this engines running. Nice vid.

Thanks for uploading. Love your videos

Thank you, thank you, thank you! Every once in awhile I get the urge to buy a Corvette. I think YOU have cured me of that urge. The lack of service room, the extensive electrical connections and superfluous plumbing and detritus attached to that car has permanently dissuaded me from ever being Corvette curious again.

Wow, that's crazy! I've never seen that before.

I'm probably in the minority of your viewers but I watch every project update and enjoy them more than the tear downs. So, hearing that we're getting an update very week is awesome!

Keep the videos coming and I'll keep watching dude.

I like playing these at higher than normal speeds just to make the frustration more palpable.

New heads, nice. Be good to see it run. 👍

That is a good lesson on the effects of uncontrolled lean fuel mixture. We've all heard about lean combustion damage but it has never been seen quite like this!

Who needs a freakin engine stand, huh?! Impressive teardown from above. Look forward to the next one

Corvettes are so much fun to work on. Use to work on them years ago.

Congratulations on your WIN with the "Nemesis" dipstick!

It's your channel, surprising holes in engines are contagious.

Enjoy your channel. Both the engine teardowns and car fixes/updates. I have a '95 that I turned into a track day car. Stripped everything out of it (including the complete hvac unit). If you need anything, let me know. The C4 has a conventional drivetrain, engine, transmission, driveshaft and rear axle. The C5 has the transmission at the rear. I bought a '95 because it has a conventional drivetrain and doesn't require a lift to work on it. With a few engine mods, upgraded to Gen3 PCM, cam, injectors, individual coils, etc. and race level suspension with Toyo R888R tires, the car is so much fun to drive on the track.

Yuk, that's more deep than I would do with anything chevy. God bless you!

Excellent video, very interesting!!

I think a different camera from usual was used. Great video!

Really like your videos especially the ones you do on vehicle restoration.

Liked for the crazy failure mode. Definitely drove like it was stolen. 😄

I think at 49K I would still put a new set of mains and big end bearings in it. Probably a set of rings as well.

That is insane to have torched out both heads like that! Would never have expected to see that.

That’s insane. Great video if this is the new norm I like it

Another great teardown video. Keep it up

Like watching a Surgery. Awesome work!

iron has a melting temp twice that of aluminum while also only conducting heat at 1/4 the rate of aluminum while only having half the specific heat capacity as aluminum. So aluminum melts faster, conducts heat faster, and holds twice as much heat as iron. There is a good reason it took decades before engine blocks became aluminum with iron sleeves, iron is damn tough!

My fav channel 😊

It's great to see an 'in situ' tear down

The editing is genius

Another great one, cheers

This is a first. I never seen that happen to cylinder heads before. Yeah definitely check the fueling issue to prevent from going lean again. I really like this channel and updates on your projects.

Love the channel. Maybe you could do a segment on best(or worst) dip stick removal.
