Fuel in the PCV line - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I reattached the vacuum line for the FPR and had perviously replaced the line between the intake manifold and the PCV. Upon taking the top of the intake off I found the vacuum line had a kink in it and was planning to replace it with a better line. I removed it from the PCV and found gas in the line. I spoke with my local Autozone guys who said that this is likely caused by a bad FPR. I haven't put the intake back on now that the vacuum line to the FPR is solid. So, would the leak in the vacuum line cause the excess fuel or is it more likely just the vacuum?

Uhh leaky o ring dumping fuel into the intake and letting it drop into the pcv...does your oil smell like gas?

I haven't pulled the oil since finding the gas in the PCV line, or really driven the car since I've bought it. I did an oil change before the PCV vacuum line was installed so it's got fresh oil. Is the O ring between the FPR and the fuel rail or between the 2 pieces of the FPR? Would this also cause the car to have performance issues after warming up in the mid to higher RPM bands?
