I have a 2003 4Motion wagon, 2.8L 30V, automatic. The PCV started leaking a couple days ago, giant vacuum leak out the vent looking port on the side of the hockey puck PCV valve. I taped over the vent to stop the vac leak and that sort of helps but it still leaks and idles rough. If I pop the cap and diaphragm off the PCV valve and just plug the line to intake, it runs great but smokes like crazy out the exhaust! What on earth could make it burn so much oil by capping off the vacuum line to intake???

Tthe part i have on the way is #6 on this diagram:

It doesn't make sense at all cause people cap off the line to intake all the time and run crankcase to a catch can.

Your both missing the big point! I had the crankcase completely isolated from the intake. Crankcase was venting to atmosphere, and the intake manifold port capped off! That is how I was expecting to bypass until the new PCV showed up but it smokes to bad.

If I connect the intake port direct to the crankcase, then the smoking quits. That's how I'm driving right now.

I'm confused, the manifold is the intake.

Sorry, I edited it but you were way to fast to reply.

Yeah, that's what I'm hoping. Just another mystery I'm gonna have to live with
