Engine = boom. Questions

This doesn't belong in the blown engine thread yet. I'll post there when/if I know exactly what happened. To make a long story short:

1. Bought used Evo from dealership - was modded to unknown degree
2. Took to shop. Was not boosting and running very rich
3. 4 days later threw a rod bearing
4. Towed back to dealer - they agree to replace bottom end with new
5. During replacement get call saying oil pump is shot also, need to order parts
6. Also say that heads were sent to machinst to "make sure no debris in them"

So, I drove the car 4 days... it's been at the dealership for 2 weeks. I'll probably get it back next week.

Important question: when I get this thing back, what are the most important things I need to look for??? Keep in mind that I did not see inside the motor at all, I'm going by what the service manager is telling me (who does seem like a cool and honest guy). I do not know what caused the failure (probably bad oil pump) in the first place. I am getting a new bottom end and oil pump. From what I know, everything else will be coming off the engine that threw the bearing. I'm not sure what's going on with the heads yet.

The car was probably tuned on E85 and the dealer or you were not aware of this!

Why would you say this ??? Who knows what or why ....

He said his car was running rich and not boosting. Was just assuming off what he said.

If they are rebuilding the motor make SURE they replace the oil cooler since it catches all the debris from the spun bearing.

A VERY important step!!

.

Anyway like stated above, don't let them get away with "cleaning/purging" the oil cooler. It never works, get a new one. Also there's only one head on the car not heads

. No V8/V6 business here.

Thanks guys. This is exactly the kind of info I need.

Coming off my GTO... forget what I'm working with here still.

I would also suggest you have them flash the ECU to stock until you learn everything about the car

I suggest you get the car out of the dealership as soon as they are done, and get the car to a reputable shop (or individual) in the Phoenix area who really knows EVOs and EVO ECUFlash tuning. Certainly, there are others in PHX here who should be able to help you with that.

Yes, this is very important. Make sure the ECU has a good flash.

I've got the tune part of it handled. I'm more worried about little mechanical things that can go wrong, or further down the driveline, etc.

Thanks for the responses.

If a bearing failed and the motor is toast that means that it most likely scattered debris throught the entire oil routing system in the engine, as various people have said just flushing the system will not be sufficient, have them replace everything or the risk for failure is still there...

ErikT · Jul 28, 2009, 05:20 PM

Ok, so I'm having the oil cooler replaced.

They won't replace "everything". That would be a crate motor.

Q15H · Jul 29, 2009, 02:37 PM

The oil cooler is a chassis part and is not included in a crate motor.
