Those of you that have followed the #ETCGdadsTruck build know that I had some difficulties just after breaking in the freshly rebuilt engine. Aside from the pinging, there seemed to be excessive blow by causing massive oil leaks on the engine.
In this video I remove the engine and tear it down to find out the cause of these problems. You might be shocked at what I find since I’ve put about 1500 miles on the truck since it was built last year. It’s amazing it ran as well as it did.
Let me know what you think went wrong in the comments.

Thanks Eric, lol you are a a great inspiration. Some of the best lessons in life come from your own mistakes, And some of the more valuable lessons I think come from watching others make mistakes. Accidental or not, something went wrong and we the RU-vid world had an opportunity to learn. And you can bet we did. I rarely do heavy line work at my job, (GM dealer), but when I do there is always something I can reference back to either in your videos or from talking/watching the old timers do it for years. Literally if I had no work I would just watch them for hours or some times days and just ask questions about what there expecting to find. What they found, and why there removing what there moving. When I did my my first engine replacement on a 6.2 Denali, it took me 1 full day, that was with no prior experience removing that engine, but because I had watched it Be done so many times and I had the opportunity to ask so many questions, I felt like it was just to easy. I have you to thank Eric and of course all the vets that strictly to heavy line work for a living. To everyone watching and still in the “heavy learning” process, if you have the chance to watch someone and especially help them, do it. Seize every opportunity you can, the best way to learn is when your not trying to beat the time on flat rating. and just focusing on the lesson to be learned.

I had an 89 chevy 1500 that the motor blew up (stock engine) in the winter of 2010.. I changed the oil a month before and I KNOW it had oil in it. We towed it home and the oil pan was empty... there was oil on the frame and engine, but also had grease buildup so oil wasn't that uncommon. I never figured out why it lost all the oil or where it went... no oil on my driveway or under my car... it TOTALLY makes sense that it blew out the dipstick, I noticed the dipstick was pushed out and oil was on the tube when I changed the oil, but young and dumb me didn't think anything of it. If one of the rings failed it would do the same thing... finally after 10 years i have closure... Thanks for making this video..

@302vettelife2 4 года назад

I'm skeptical that the broken pistons resulted in the coolant in the crankcase. I would have a machine shop check that block for cracks. 11:1 is by no means 'too high' for a street car. If the truck is a daily driver, i would get it down to 9.5.

@Motor-City-Mike 4 года назад

Eric, definitely detonation damage - nothing else will crack ring lands like that. Look up inside the insulator of the spark plugs and you'll see little flecks of aluminum, that's the aluminum that went molten that came off the pistons. For those headers - Cut the header flanges between cyls. 1/3, 5/7, 2/4, and 6/8. This lets the tubes move or twist slightly when they're tightened and seat squarely against the head. Getting all four tubes flat at the flanges with a belt sander is absolute murder. Most SBC headers with a single flange for all four tubes leak sooner or later unless you cut the flanges - after the first couple times I ran into this a friend told me about cutting the flanges, I did from then on and never had the problem again.

zeroyon223 it’s a product of high compressi n and hot spots in the cylinder. I have never seen ring lands blow up like this during regular detonation on a N/A engine.

@sethgibowski8695 4 года назад

@zeroyon223 correct. LSPI is a mix of low rpm, high cylinder pressure, and excessive blow by or carbon build up on valves that ignites the fuel mix before the spark plug actually fires. Basically stay out of boost at low rpms. LSPI is also mainly common on small displacement 3 and 4 cylinders where the stock turbo is so small that itll make heaps of boost nearly close to idle rpms if you dont shift right.

9.5:1 compression ratio is perfect for good reliability on the street & pump gas....IMHO...and never go past 10:1 unless you want misbehavior & the associated issues. Too much cam “overlap” will exasperate those kind of issues too so I stay pretty conservative with cam choices.

If it's that simple, why not even consider the comp ratio? I mean, if it 's that important why wouldn't it be the first thing a machinist asks or advises on? Even more basic, why isn't there a spreadsheet showing comp ratios vs gas type? I'm thinking there's more to it than type of gas.

@invertedpolarity6890 4 года назад

11:1 compression is too high for pump gas on a small block. Edit: I understand a lot of modern engines can run over 10:1 compression and not have a problem. But understand modern engines have knock sensors that can detect knock and back off the timing. Most modern engines also use DI which allows much finer fuel control which allows high compression without detonation. Mr. Eric's truck engine is a small block chevy V8 that (as far as I know) does not have knock sensors or modern design elements that allow high compression.

@ericthecarguy 4 года назад

I agree.

@andreasmaltcke117 4 года назад

"11:1 compression is to high" for a normal / everyday car For racing cars it is quite safe compression (still is), but such engines do not live very long. Everything above 9.5: 1 is (or may be) "too much", especially for V8 engines not designed for racing. (replacing the main components with "better equivalents" does not solve all and every problems) Some Japanese and European engines can work 10: 1 compression without problems (these are the factory parameters), and we can even increase compression above 11: 1. And the engine won't break down after traveling 1,000 miles (kilometers?). Such engines use variable valve timing and direct injection, and a few other tricks to reduce detonation at high or low engine speed. Not every/any engine of this "good" model will withstand, and not always (in all conditions). In my opinion, the key is to use VVT (some type). Old engines do not have this, and therefore any increase in compression is much more difficult than in newer engines (Honda - for example).

@ToxicMisfitsYt 4 года назад

Shane Broussard well not really. He should have 10.6:1 because the blocks not zero decked. You can easily get by with 11:1 with aluminum heads and a decent duration cam

@ToxicMisfitsYt 4 года назад

Andreas Maltcke 10:5-11:1 is safe on aluminum headed engines that have a decent size cam or gasoline direct injection. High duration cam bleeds off some cranking compression because the valve closing and opening events. Anything under 200 cranking compression psi with the popular psi and afr will be good

@ginnai 4 года назад

@AliasSLH I'd be curious to understand the difference between cylinder count / rev range impacts compression numbers; I'd imagine the biggest issue would be heat and thus tuning & timing are big factors. Larger engines will be more subject to heat than smaller, volume ^3 while surface area is ^2 (volume increases faster than size). I've driven 6 and 8 cylinder cars and pedal down, you can watch the heat build... never seen that with my teeny Honda motors. More to why big engines have lower revs than just balance and heavy bits.

patx35 True. I was running 93 octane at the time, which likely isn't enough for an 11:1 compression ratio. I would not have run a compression ratio that high had I known about it. An 11:1 engine would run fine on race gas though.

@@ericthecarguy Wondering if you could run E 85 on this. Is there a place to hook up a fuel sensor to detect the E 85?

@chadcollyer4957 4 года назад

@@WickedProxy E85 is not needed on a relatively low compression SBC. This is all in the tune, this is why any half way decent tuner will start low on timing and sneak up on it.

I guess I'm curious about how these events have impacted your desire to be a builder. You were very excited about the prospect of heading that way, but the issues you've had with the engines and audience with these two projects have likely altered your opinion. That said, growth is painful and expensive. I've always respected your approach to working through issues and being really honest about when a mistake is made. I am curious for your thought process on where this puts ETCG as a channel and where you are with all of this.

@ericthecarguy 4 года назад

Like you said, "growth is painful and expensive". I love building and plan to continue with it. For me, this was partly on me for not asking the right questions. In the future, I'll be sure to ask about the compression ratio BEFORE I blow my engine up.

@ginnai 4 года назад

@@ericthecarguy haha, knowing what questions is the hardest part. I installed my 91's suspension 6 times before I got it right. By the time I was replacing the 97's, I was done in 2-3 hours😂; full disclosure, I still missed torque on two bolts😞.

@kstricl 4 года назад

Sounds like the correct conclusion. Good call dropping the compression, better to leave a little power on the table than to be replacing parts all of the time. I remember an article from Hot Rod magazine in the 90's on a guy running a Nova with 14:1 compression in a drag car. He would daily the car, but to do so on pump gas (93 octane), he had to back the timing waaay down (to like 10-14 degrees IIRC) and had the biggest rad in LA in a street car.

@Itsnotmeok01 4 года назад

Great video Eric 👍

@awesomebob517 4 года назад

Higher octane fuel my friend, you have a high compression engine, the higher the compression the more heat you create. As long as stay below 12:1 compression, 93 should be fine without pinging.

@simonatkinson1107 4 года назад

Looks like you were using a diesel compression ratio in a gasoline engine. Perhaps a little too high for that set up.

@timramich 4 года назад

11:1 isn't that high, especially using aluminum heads. I still don't know what pump gas means. 87 octane? 89? 91? 93? I guess for an old-timey SBC 11:1 is quite high. Funny how the modern V8 engines run numbers like that or higher on just premium pump gas.

@simonatkinson1107 4 года назад

11:1 is the higher end of the gasoline ratios used. Diesels start about 14:1. “Pump Gas” usually refers to the standard gasoline you buy at any gas station.

@scottchamberlain5594 4 года назад

@@Rotttman Alright, I'll bite. As I recall, the Fairmont had detonation issues. The MINI, if I'm not mistaken, had assembly issues. Not that I'm judging. As a former MINI victim (X2!). They are not simple or logic cars to work on. Nor were they well engineered in the first place. I guess one possible take away is that engine building starts with design, and that maybe putting together an engine is something better done in a shop devoted to such things.

@@scottchamberlain5594 They knew he wanted this as a street able, pump gas car. Compression ratio too high!

@scottchamberlain5594 4 года назад

@@Rotttman Eric seems susceptible to 'mission creep'! The Fairmont was once a nice little old lady coupe, that was going to get a 5.0. Ends up as turbocharged race car. Nothing wrong with that, but if I were doing a long distance cruiser, you could design one a lot simpler, cheaper and better suited to the way he uses it. And just as fast. Not in any way a critique of the build- it was an interesting trip! I would not be surprised to leave him my lawn tractor, and find it with an intercooler, running race gas.

@olemansailor6519 4 года назад

I had a 429Ford engine with 11:1 compression and I had to pull the initial timing back just like you said to keep it from pinging like mad. I also ran 104+ in it because in a big block I couldn't live with the gas mileage with the timing cut back to zero. Of course that was when 104+ was $3.75 a bottle. I have seen engines with excessive detonation and agree with you. Good luck.

What did he do wrong? Eric was pretty vague and any performance engine shop is going to err on what makes more power. Pump gas can mean 91 octane winter swill or 104 unleaded, depending on where you are located, entirely possible Eric could have gotten some bad fuel too. 11:1 SBC's on pump gas in a street vehicle is fine but that means you are dumping in octane boosters or buying specialty gas.

Many years ago, an old mate of mine took his Ford Escort MK2 to his local dyno to have his twin DCOE Webbers "Set Up".. Having just rebuilt the Ford "Pinto" 2 litre OHC motor... The Bloke doing the dyno was known to be a "Bit of a Knob!" and not very good opperating his machinery! (lol!) But.... Being we were situated in deepest Wales, its was the only dyno here at the time! So... The car was strapped down, started up and imediately the throttle was pinned! The thing was screaming at umpteen thousand RPM's and through the ear bleeding mechanical abuse one could hear the distant crackle of the dreaded "Death Rattle!" Then... There was a loud BANG! Burned oil infused smoke filling the room as the rollers slowed down until the only thing to be heard was the crackling of burning fluids.... On inspection... The whole of number one cylinder including head and crankshaft had decided they had had enough and parted company with the rest of the engine block.... The only things keeping them together was the rocker cover, rather knackered camshaft, inlet manifold and sump! Once they were removed the thing just fell to bits!! You knocked the nail on the head with your diagnosis Eric... Comp to high, Timing out and crap pump gas (Its Petrol over here!)...(and we have "Super Unleaded!")....(lol.!)... Cheers Mate..
