Hello all I have a recent issue on my 1997 V90. I thought I had my oil leaks cured but I believe I have a pcv system issue. Does this car have what is called a Flame Trap? I have not found what is referred to as a pcv valve that I am familiar with in the past. I have a positive pressure at the oil filler cap and a slow leak spilling under the spark plug/coil cover. I have found threads on this but all were on FWD 5 cyl cars but they all said its a common problem and the pcv and or flame trap systems were probably plugged.
I am sure this system has probably not been serviced recently.
Sorry for being long-winded, I am unfamiliar with this system. Heard it was under the intake manifold. Is there something I can take apart and clean? I will start looking for damaged/worn hoses today.
Any help, direction, pics would be GREATLY appreciated.

 

Yes, the 960's are white blocks and do have issues with vacuum venting but it is very rare. If you follow the tubes off of the intake tubing you will find the flame trap and I'm pretty sure it does have an oil separator box in there somewhere. Vacuum elbow leaks are usually the problem.

 

Thanks - I will trace all that down and clean what I can today then order some new components.
