Yikes ... It may be the head gasket beginning to leak.

There's also the possibility that whoever installed your engine internals didn't do it properly.

 

The only way I can think of getting oil on top of the piston, is that the piston rings are not installed right. I had a shop assemble my block so im not sure if they machine the piston rings to fit. If your getting oil leaking oil between the block and trans. Maybe the block or head wasn't decked right.

 

Yah but the leeking oil betwen my trans and motor was another job he dind it was leeking where my crank case is. i was wondering if it could be my valve ?

 

It could be leaky valve seals. If not then rings. Or blown head gasket. I got oil on my pistons too. Fresh rebuild. I need mine checked out.

 

Sombody else knows what shoud i cheek :S ?
