OK this is real stupid. When I was working on my car I droped a small washer and never figured out where it went till I drove around the block. It seems the washer fell in my intake tube and the turbo blew it into the cylinder. When it happened it destroyed the top of one JE piston and the head by making pock marks everywhere.

My real delima is that while the motor was running it was making a knocking sound that I thought was a spun bearing. I removed the oil pan, oil filter, and oil pick-up but they were all clean. No signs of metal shavings anywhere. I removed the piston that was damaged and its bearings look fine. Is there some other way to tell if it was rod knock from the bearings? I hate to put everything back together and still have a major problem.

One more thing. Does anyone know where you can buy one JE piston?
I have another head so I'm not worried about that.

Sleeved H23 block
JE 9.0 :1 CR pistons
Oliver rods

 

I would give JE a call up themselves to ask if they will sell just one.

And I would think that the knocking you heard while the car was running was due to the washer making contact w/ the head and piston.

Word...

 

or one of your valves is fucked...doa compression check.

but if you know your piston has pocmarks you already pulled the head?

 

Yep, head is off and the piston is out of the block. I have two other h23 heads so I am going to use one of them in case a valve is messed up.

well isn't that sweet just having 2 extra heads lying around.

how i would do it. reassemble with the head. and new piston, and see if it knocks. it would suck to rip apart the whole motor for nothing. and taking the bottom end apart is no easy task
