Somehow i get a fair amount of gas in my oil. I am not sure if its the injectors or the FPR then maybe going though the IM and into the cylinders? What do you guys things?

 

What about running mad rich, maybe ur tune what do ur a/f look like?

 

na tune is fine, i just had it done

 

piston rings.

 

well the pistons dont quite fit right, i know that there is some piston slap, but when the engine is running the pistons swell up and then theres no trouble....its when its just turned off that gas seeps so im just wondering where its coming from?

 

do you ever have an extended crank before the motor fires?

possibly a leaky injector

 

Piston fitment would have to be pretty shabby & your car would have to spend alot of time in a rich, open loop condition (slow warm up after cold start)to get alot of fuel in the oil that way. How long ago was the rebuild & are they the original inj's? How long did the inj's (stock or not) sit before install & have they been cleaned/flowed on a bench? I see sticky inj's often so Im inclined to lean twards that. Is it a stock ecu?

 

no nothing is stock, they are rc 650cc injectors.....and yeah they did sit for a good number of months before being used.
