Hell, if you can attach a hose and have it go to the rear of the car and install a catch can there and THEN vent it. It could work. The vapor would have plenty of time to cool down.

There's lots of options. The key I think is to pick one and try it.

I'm planning on running the ProVent 200.

Neat...a little pricey brand new, they look like something that would be factory installed for some applications, hit up the wreckers, replace filter and profit

Very cool. I'd be a 'little' concerned about the filter really slowing down flow in an open aplication, but they look like very neat little seperators.

If they were oem, we should find a list of trucks that used them.

With the rallycar I reach up there with a shoprag intermittently and give it a wipe.

The 9" rear has a drip that is annoying. About a drop per month.

Seems the oil coming out is clean enough to return to the sump (with a check valve)

Interesting.

They are designed to be run open or closed.

Yep that's the nice part, and if you do run it in a closed loop it shouldn't be puking oil in the intake.

Where are they sold?

Where I'm planning on using this, I could plumb the drainback into the turbo drain hose. Is that under pressure?

I would love to get some feedback from someone using (actually installed) that is working? That Mann separator looks good, but again I would hate to be the guine pig, only to find out it can't handle the flow our overboosted cars have....

Yes, the oil drain is under crank case pressure. The only line not under any pressure is the stock rubber hose from the pcv box on the block that acutally is submerged in oil.

Yes it either needs to be submerged in oil or use an inline check valve they sell

It should work just fine. It's designed for engines with a higher output than most have on this board

Homer wins.

I think I'll do this as soon as I take care of an oil leak (discussed in another thread)

You guys will do better giving the engine another tenth of a pound of boost and keeping your junk in good health!

I'll post up some setup pics once this guy arrives. I'd expect early next week.
This is going on a whiteblock.

Even a brand new engine will have blowby. I'm personally not trying to bandaid a broke ass engine, I just don't want a half assed oil separator dumping oil into my intake.

Especially if you're building for higher output - ring gap, etc is generally going to be greater to allow for the higher loads/ greater expansion under high rpm/ boost levels.

I'm mOstly curious about the Provent 400 in terms of oil vapor smell - that's the only thing I don't care for with VTA, and mine isn't that bad/ or particularly noticeable.

Yeah. Although the 400 is rather large and looks like a pain to get ahold of. You can run two 200s in parallel.

I cut apart the unused A/C accumulator dryer on my 88 765 and fabbed up a catch can. It's mounted in the stock location using the stock mounting bracket.
