Thanks dude .. D_stirls post in that thread was really helpful .. Although it sounds like the line i am talking about would be best ran to a catch can or vented (the one venting crank case pressure to head) .. Thoughts ?

Don't vent anything. The whole system is supposed to be under vacuum. On a fresh built motor you might not notice any side effects for a while, but on ~20 year old motors you start seeing more blow-by, and silly things like the dipstick popping out.

Pull the PCV valve out and shake it. If it rattles, it's f**ked. It's lost spring tension, and won't do what it's meant to. Replace it with a new one from Nissan. They're not very dear.

There is no spring tension, it is a valve that is solely controlled by vacuum.. If you shake it the plunger will move freely and make a rattling sound..

yep

 

i'd say if it doesn't rattle then it must be gummed up and dirty inside and then it will need cleaning or replacing.

 

btw welcome back meminto!
