ok, most people know here that one of the most common things to fail on a honda engine with boost is the ring lands, right? i have had a couple of engines do it to me until now, and it was one of the most abused engines of the bunch. This is the engine we ran all last year threwout all the of the track and the constant 2step, just flat out trying to hurt it.
Well the engine lost compression onth #4 cylinder late last year and the other pistons followed shortly after they were like this
#4 52psi #3 47psi #2 87psi #1 105psi
also note that i drove it around like this for a couple of weeks and then parked it a few months ago and then drove it to the shop last week.
We start to pull it apart and it just stinks of burnt oil, the head studs are really tight on the outside bolts and no so bad in the middle ones, we get the head off and start looking for scaring on the cylinders, we are rotateing
the engine and it is not sticking, no problems pushing them down and there is apsolutely no damage to the cylinders for where we could see, odd to a point.
At this point we are interested now in pulling the pistons so wer start that process. We start with the #3 and everything looks fine, meaning there is nothing wrong with the piston even the rings don't seem that bad.
we pull out the other three and the same thing there is no issues with the pistons they are intact, not even any scrapes on the skirts.
The whole thing is just surprising to be honest, servion set it up to be a conservative tune, just to be safe since the engine was kinda low compression to begin with. I'm gonna just hone it rering it and try the sme one out again, why the hell not.
all that hell we put it threw and it looks like a basic old engine rebuild.
i bet if we would have had the guys at honda take a look they wouldn't have even know it was boosted, i've got to get some pics up but it's still hard to see the cylinders unless your looking at it in person.
sorry just a rant, i just wanted to thank servion for tuning the car, if it could hold together like that with me driving it, he had that thing tuned great and safe. i was figuring machine shop time after what we were doing to it.
