Ok here's the story's I bought an 03 Evo drove it two days while running 89 stopped after work put in 93 and on my way home it threw the piston out the bottom of the engine. Bought a used engine just got done putting it in today and fired it up ran fine while idling and all the sudden started knocking. What is caused this? Something is burning my engines up even at idle

The common denominator is you. You are likely doing it wrong. Pay someone who is proven competent to do it for you. Not trying to be rude but doing stuff beyond your competency ends up costing a lot more than just having it done right the first time.

did you change oil coolers after the first engine popped?

When your motor has a catastrophic failure you need to replace everything oil touches. Especially the oil cooler

Might be unrelated, rebuild the used engine you bought:

- with stronger internals if you can Rods & Pistons, etc.
or
- just give it a full overhaul if you on a budget: Rings, Bearings, fluids etc...

have everything stripped and cleaned properly to make sure theres no contamination.

Try and get a good engine builder to do the job for you.

Do you have any way to monitor oil pressure? If not, then you need an oil pressure gauge installed in the car.

FYI - I knew someone who had similar issues. After burning up the bearings in several motors a professional checked out his stuff. Long story short it was discovered that his oil pan was dented right where the oil pump pick-up tube sat in the bottom of the oil pan. The inlet of the tube was pressed against the bottom of the pan because of the dent and the result was starved bearings.

You guys are being very helpful and I appreciate it. I did flush the whole cooler until it was cleaned is that not good enough? Changed oil pumps and cleaned anything the oil touches any feedback would be great. Pockets are running dry thanks

Some say you'll never get all the metal out by "flushing it out"

I know some vendors have sent them for ultrasonic cleaning to get them cleaned to where they felt comfortable putting the used oil cooler back on the car with the new engine.

Personally I'd get an aftermarket cooler at that point

No, not good enough. It was one of the pro-shops on here a while back (maybe STM or buschur honestly don't remember) that blew a motor and tried to scrub their oil cooler for two days before giving up and getting a new one (said that no matter what they seemed to do they kept getting metal out of it). Really the extra 600 bucks is worth it just to be safe even if you think its clean.

Did you drain the bad gas out before you installed the new motor?

Damn. There was no fuel left in the new engines system. I did not swap fuel out I bought a full tank of 93 from shell my car ran fine two days before on 87 I asked a few people if it could cause these problems and they said no. But the only thing I've done different is run this 93 and since it's been in there two engines have blown well one knocks the first through the piston out the bottom of the block. Should I take some of this fuel and test it somewhere?
