first off i can't post pics so i have to link to ebay for an example:

ok, i have an inlet for my turbo like the one in the pic (bottom row middle that says "ford inlet"). i need to know if the fitting on the inlet would be vacuum source, or if it would allow air to flow through it in the opposite direction? i ask this because i need a vacuum source for my pcv system, and i don't have room for an intake pipe. i was thinking that it would work, but i'm not sure now because the fitting is angled towards the opening instead of perpendicular to the side of the pipe. sorry for having to link to an example.

 

The vacuum source should be after the compressor wheel. Ideally, somewhere on the manifold. Is there some reason you cannot plug the PCV system into the nipple underneath the intake manifold where it normally goes?

Isn't sucking and blowing the same thing? :chuckles:

 

ha i didn't think of it that way...but anyway plugging into the intake manifold would become boost and close the pcv valve, but before the turbo would be constant vacuum, at least that's what i thought. i have researched pcv setups on turboed cars and some people say to use the pre-turbo vacuum source, and some people say that it's fine to use the stock setup. the pre-turbo setup just seemed safer to me.

 

Just get a catch can and you won't have to worry about burning all that blowby that the turbo causes.

I hope we are talking about the same thing: Are you referring to the hose coming out of the valve cover or the hose that directly connects the PCV valve to the intake manifold? The first one sucks air through constantly and the second one carries oil vapor to the manifold to be burned.

The only problem I see with the preturbo setup is that it will always be vacuum and it will suck oil blowby right into the compressor wheel and gunk up the piping and intercooler. So, get a catch can and route it normally.

 

i have a catch can installed between the pcv valve, which is hollowed out, and the intake pipe. i have a breather filter on the valve cover. here is where i got the idea:

That doesn't look like a good idea. Like I said before, it will most likely clog up the compressor wheel, intercooler, and piping with oil sludge that is supposed to be dumped further upstream to eliminate any buildup.

I have the breather filter and a hollow catch can leading from my stock PCV valve and plugging in underneath the manifold. I haven't had any problems what so ever.
