Ok. ...I have a freshly build d16a6 and now there is oil in the piston...anyone have any clue what is the problem?? need help big time....and i can't seem to set the timing right...the white line, lines up to tcd, but when shot with timing gun the red mark reads around 3 degree...need help........

 

If you have oil in the piston, then i think i have bad news for you. The oil is probably getting past the piston rings which means that the person that built the engine didnt do a good job.

I would do a compression test to see what condition the engine is under.

My guess is that you will have bad compression. Next, do a leakage test to see how much air is going through the rings.

 

i agree. bad rings..

 

So oil has somehow penetrated the metal that the piston is made out of?? I'm just joking, I think I know what you mean. Do a compression check. It may not be rings. Valve seals being bad can also introduce oil into the combustion chamber.

 

true.. most of us think rings all the time..

 

the head is also freshly fully build too....

Did you do a compression check yet? That is the first thing you need to do. Then do leakdown.
