Really now. A catch can does a GREAT job of stopping the oil, theres no physical way for the oil to make it past the catch can unless you let the catch can get completely full and the breather filter inline actually does help because part of the problem is the baffling is inadequate and the breather filter adds additional baffling. There are lots of people who have 0 issues with the stock pcv system, if you maintain your pcv system it works great, if you let issues develop then no it doesnt work so great.

 

Ok I keep finding different ways to solve this problem, but no real agreement on how to fix it. Not saying that what everyone above is doing is or isn't working, but there are alot of arguements of the "proper" way to fix this.

My problem was oil in my TB and intake, BAD! To the point that it was leaking down my elbow and the whole inside of the intake was completely coated. When I got my motor tore completely down the bottom of the intake manifold was completely caked up with oil/grease and the metal part that bolts to the bottom of the intake has about 1/8"-1/4" of build up on it.

Now from what I have read is that you should add a oil/water seperator between the PCV and the intake. Or should the seperator be inbetween the fresh air tube and the TB? I want this problem fixed, no matter what should be done. I strongly feel that this was the start of all of the problems that my car had (spun rod bearing, wore cam bearings, broken rings, and residue buildup through out the inside of my motor at only 120K miles)

Now with my motor being completely new, what will be the best way to keep my it clean and keep the oil out of the intake and TB???

Sorry for the big thread jack, but I personally think that this is a serious problem on these motors, but proper maitence should help things from ending up like mine (I only put 150 miles on my car after I bought it before the rod bearing let go)

 

Choose one of the options here in the thread, give it a try and see how well it works for you. I came up with my own crankcase breather solution and it works great!

Catch cans don't top 100% of the oil vapors. And alot of the oil gets in through the fresh air hose and that little purloator breather filter doesn't stop the vapors from making it into the tb/intake manifold.

 

You already know this to not be true from the other thread you've replied in, why do you continue to argue for something you've been proved wrong on?

 

How does a catch can catch "vapor"? It works by dropping the velocity of the gas/liquid stream low enough that the entrained droplets fall out. Sometimes they add a baffle or centrifugal path to help knock the droplets out. But the catch can will not separate oil vapor (gas phase) from the air and other gases coming from the crankcase.

 

This explanation of the type of filter with in the catch can may help.
