Very good point.
How would that have gotten through the innercooler?
The truck was wrecked & the intercooler was destroyed & the tubes were ripped off before I bought the engine.
The turbo is not hurt. I disassembled it to check everything.
I'm assuming something was injested in the open intake bypassing the intercooler either during the accident or from removal.
I ran the engine with it removed from the truck with no noises. I then stripped the engine down & taped off the openings, so I highly doubt I got something in there.
From all I can determine, it never ran with this part in the engine.
The piston & head only had a small clean spot where it touched. No chewed marks in either. No marks on the valve or seat.
I'm guessing that while rolling the engine around it must have worked its way into the port & maybe dropped through an open valve while i was taking out the converter bolts, or it somehow layed in the cup of the piston & never got smashed while running (unlikely).
There was enough slime in the intake (oil & soot) to catch almost any moving part. So maybe this prevented it falling into the engine before I pulled the intake.
At least it happened the way it did before something self destructed.
