As many of you know replaced my plenum plate with the kit from hughes. I got a chance to look down the TB tonight and noticed a light coat of oil on the new plate and oil running down the right side of the intake where to pcv valve goes to. Im pretty sure its not the plate/gasket thats leaking. I torqued the intake and plenum plate bolts to spec, (84 in lbs) and double and tripple checked them. I also used blue threadlocker. Its only been 150 miles since the plenum replacement. I installed a new pcv valve from autozone, along with a new hose. I used a gas line I had laying aroung it fits snuggly. I noticed that I forgot to hook up the left (pass. side) pcv hose to my FIPK air intake, but I dont think that would matter too much? I tried to get a picture of the oil on the right side. What is causing this??

here is another picture, you can kind of see the new plenum plate is damp from oil, along with heavy oil on the right side by pcv valve inlet

here is my solution. oil/water separator installed in the pcv valve line. that is most likely where the oil is coming from.

 

I did something similiar to CrazzyWolf plus used a factory PCV valve which are supposed to do a better job, After about 850 miles I have about a 1/16 inch of oil in the jar.

 

well thats one way to do it, but is this normal? why not just unplug it

 

The Autozone pcv isn't helping. If you read the plenum sticky, you'd know to get a Mopar pcv. As far as disconnecting goes, I did just that on mine. I put a breather in like old school.

 

I have a K&N air breather, and the passenger side does go to the back of the air breather hat, but the right driver side still goes straight to the side of the intake from the valve cover. Did you just split it to run to both pcvs'? how did you plug the inlets on the intake mani? also, how do you get the passeneger pcv out? I had the valve covers off and couldnt get it out wihtout feeling like it was going to break.

@crazzywolf
what did you use to build one of those?

just dont say it looks like a leaky plenum!....

 

Catch can. And it would probably have been better to put this in your original thread (zman is slacking! )

 

yea sorry gd, I just got excited to post again

can you buy these catch cans, like whats used for marine engines? or is it someting I have to fab up? But is this normal???

 

Search catch can on ebay. I put one on mine and plenum is still clean. Typically used in racing. I have a better photo - just can't find it. Catch can is below gauge set.



This is draining it during oil change.
