Another OCC question!!
 

I've done a good amount of searching to find no specific answer. So at the risk of asking a stupid question, here goes.

A PCV system is designed to vent crankcase pressure. In our case that pressure along with some oil and other small debris is vented directly into the intake manifold. The can catches the unwanted debris and allows the pressured air to pass into the intake. We are adding pcv valves to stop intake pressure from escaping but also allow the crankcase pressure in correct???????
Here's my question
Why not block off the the fitting at the IM and simply not vent the crankcase pressure to the IM at all, and simply ad a breather filter to the top of the OCC and vent it there???
I have this looming feeling that I'm missing something, so please chime in
Thanx

Where would the vaccume affect to suck cc air come from. That is why the bottom is plummed to the manifold and the top goes to the intake. So that there is a constant force sucking it.
Can it be done your way yes look at the ssp desighn. But with the addition of vaccume, alot more guys have had better results then without it.

People do this, it's called a VTA catch can, but it does not always work as well. It probably does work well under WOT if you have issues with blow by, but at idle/low load it will not be venting much of anything.

Will you suck my crankcase?

I don't care enough to go look for it right now, but Matt Damond has a thread on here about different OCC set ups and their testing.

Only if i get something in return for it. Otherwise your blow by issues are yours to deal with.

I thought we had something special...

It was special..... I had planned to do this in person and im sorry to do it here but what we had was just a phase and I must move on. Im sorry. We can still be friends.
