Smoke is coming out the front valve cover breather. like a lit cigarrette hanging on the front valve cover. Only does it when hot. my breather is wet with oil after a while. Bad rings??? losing compression?? 189000km engine, 96 maxima. I'm about the put a nitrous wet kit in there and I want my engine to last. No ways to change the timing and shooting for a 75shot. im confident it will last cause its built tough OEM but anything can happen with a sick mill...

Any advices...Catch can or the motor is already hurt??? Still runs strong as before but It smells when I get on it hard like full 1rst through 3rd gear...or downshifting from 5th to 3rd on the highway...

 

What PCV setup are you running with the VI swap?
