I have searched around and can't really find anything that fits what I have going on. When I installed my dual bypass i noticed allot of oil in my intake, I cleaned it out checked the tube on the back of the valve cover and well didnt find anything. I didnt really think to much about it till today when I was installing my phenolic spacer, and intake had allot of oil in it. I noticed the intake runners on the head also coated in oil. Checked my air intake and it was clean. So i am guessing my head has seals bad. My main question is will I need to pull the head to change the valve seals or can I change them like I use to on my V8 cars and pressurize the cylinder with air to keep the valves up. It isnt using to much oil but is puffing some smoke during shifts. Dosent really make any since to me sice this car has been taken car of its whole life, with regular oil changes.

Pcv valve in the intake manifold is probably not function correctly. Nor the pcv valve going to the intake

I thought we didnt have PCV valves on the 2.0's

All cars need pcv valves and the epa doesnt want you dumping them into the atmosphere.

Here is the one in the intake:

Valve LSJ PCV 55557180

Where is it located? I have looked all over the engine and can't find it

I stand corrected its in the head, between cylinders 2 and 3. It dumps into the intake manifold

I ordered one should have it this weekend, hope it fixes it. Has any of you guys used seafoam in your car? I have used it is allot of NA cars but never a SC car? Will it hurt it at all?

I sea foamed my car, didn't have any issue afterward. But I didn't just dump seafoam in, I believe I pulled the port from brake booster(chocked the wheels) and had my sister hold the rpms around 2-3k ish. I have an 07 lsj and was at like 90k when I did it

The ol' Seafoam does nothing for a PCV system though.
