PCV system. PLEASE HELP! Hey guys I just put on new heads yesterday and pulled off the intake today b/c I thought I had a leaky head gasket... turns out it was just the plug in the back of the head not screwed down tight.
Anyway I noticed that there is a large amount of oil on the intake ports of the heads. I am not pleased with this...
I already have a catchcan. and it is fills up fast now...
I was wondring what else can I do?
Instead of running the other hose coming from the catchcan and into the intake... can I put a breather on the hose and cap the intake?
So it would be a hose coming from valley cover to catcan then to breather with a capped intake.
I am worried about Vacuum problems... I really do not know much about Vacuums.... But I would really like to keep the oil out of my heads....
Please help me with this!

Besides doing a LS6 PCV... Is there any thing else I can do?
Is the "valley cover to catcan then to breather with a capped intake" possible?
Thanks man, I really value your opinion!

No need for catch can if you go breather route.
Either driver to passenger link and 1 breather at oil fill tube, or 1 breather in back of driver and 1 at oil fill tube
(both with capped intake)

But I am a little confused... Just to let you know I have a LS2.
Right now there is the:
Hose that comes of the valley cover and goes through a catchcan which is then dumped in the IM.
Then there is a hose that comes off the passenger valve cover and then dumps in the Intake tube right before the tb.
I would really really appreciate if you could explain to me how I would set this up! Thanks!

sorry i didn't pay attention to the LS2 part.
That means you have a LS6 PCV setup (same same).
Is your car a LS2 transplant or a goat?
1- raise the catchcan position to make the angle steeper for the oil to climb.
2- If the oil is comming from the can, then you need to baffle the passage to reduce oil suction.
3- oil could be comming via the cover to TB opening, you could run a clear fuel filter in line on that hose to verify that.
Another choice is run a breather on the oil fill tube and cap valley cover, valve cover, TB and intake.
It is not normal to be sucking so much oil.

It is not just oil... It also has a lot of water/condensation in it... I bet it is from leaving my motor "open" for 3 weeks.
I think I may go the breather route. Do you think it will be ok to do this?
I don't want to screw anything up...
Thanks soo much man!
EDIT: it is a 2005 Goat
