PCV valve?

[Guest loren]

I'm redoing my catch can setup, since it's currently sh1t and still allows oil into the IC etc.

I had a look at the black T (kind of) section that connects the block to the intake manifold and the intake pipe. I thought it was called the PCV valve, but I took it out and it's just a T... there's no valve at all.

The entry into the intake manifold itself does have a valve, air can get into the manifold but not out...so is that the PCV valve, not the T thing? Or is there another value where

the T connects to the block?

Anyway, do I really need to allow the crankcase gases into the intake manifold, or can

all the gas from the crankcase go the catch can and vent to atmo?

Yes I know there's lot's CR4P about this all over the interweb.

I am going to vent the head breathers to atmo, and the side of the T that goes to the intake pipe was

going to be vented also... if I don't need the PCV I'll vent that too.

The PCV is directly under the throttle body on turbo manifolds. The pipe on the block is the crankcase breather, the plastic tee is just a joiner.

The valve can be unscrewed and a plug or large bolt fitted to blank the hole off.

[Guest loren]

So thinking about this a bit... seems like the PVC system on a turbo is a big waste of time, since

it'll be closed whenever any load is present.

it sucks out all the bad gasses from the crank case when its under vacuum though doesn't it?

I had my PCV blocked off and crank and head breather all fed into the one can venting to atmosphere. My understanding of it set up this way is that its using any blowby to force the gases out, rather than the PVC system sucking them out (more efficent at getting rid of ALL of the gasses)

...but I did read it in the net

i have a few in-hex 3/8th bsp plugsthat you can have to blank the manifold off if you want loren

[Guest loren]

Yeah sounds good boostin, thanks. I'll pm you.

I welded the PCV valve hole up on the valve and just screwed it back in Loren on my setup.
