As long as there is a breather pipe going back to the intake pipe there's no dramas, the tool that put a can in my car before I got it had it all wrong and it pumped heaps of oil out the exhaust. Would work better inline with the breather pipe though (i.e. inlet side of the rocker cover > exhaust side > catchcan > intake pipe) :no:

are u trying to catch cans?

:P

:no:

what is that doo-dad core thingy behind the drivers light infront of the radiator? is that a series 2 thingy?

I don't know, looks like some sort of cooler, I'm guessing it could be auto transmission oil cooler?

yep, its an auto tranny cooler.

as long as you've got a breather on the catch can as well as the other pipe thats on the exhaust side blocked off (the one with 2 coming out of it) you should have no problems.

The passenger rocker cover is still feeding oil vapours back into the inlet side of the turbo.

In my installation, the catch can basically replaces the hose from the passenger side rocker to the turbo inlet (that 'U'-shaped hose coming straight up off the passenger side rocker).

If there is no breather OR it doesnt breath back to the intake pipe, crankcase pressure will throw oil out of the dipstick. When I got my car, there was a hose from the intake manifold > inlet rocker cover blocked off. There was then 2 hoses going from each rocker cover to the catchcan with no breather.

The engine was throwing HEAPS of oil out of the exhaust, I reconnected the hose from intake manifold to inlet rocker cover and it stopped throwing it out the exhaust, instead it started trying to throw it out the dipstick. It was abotu then that I realised it wasn't breathing.. so yes there are wrong ways to hook them up :woot:

ohh i see now, i knew the function of the catch can but didnt know it could build presure.. iv seen catch cans with and without baffles n steel wool n that, why is that in there? capture the vapour and slow things down?...

    • This issue has been there between twins and singles… it ain’t the hot side.
    • This actually makes more sense than what I'm suggesting, which would make me feel happier anyway. I just reached for an idea on the cold side because the tests on the hot side theoretically ruled out WG problems. But now that you mention it, it did bother me that a 12 psi spring on what is supposed to be a good WG setup is on able to get down to 20 psi. That's bullshit. Read that way, that WG is not doing what it is supposed to.
    • If you have a valve, set to 12PSi, and when it ramps up, it goes out to 23PSi, and then settles for a consistent 20PSi and thats the lowest it will go, then I'd be suspecting you have an issue getting enough air to flow AROUND the turbo on the hot side. Now, this could directly flow into what GTSBoy is saying, and that's effectively that your skinny ports aren't able to get enough of the air through the head. Remember, boost isn't a measure of air flow, it's a measure of restriction. And if the turbo at max bypass around it is still able to deliver more air than the head can ingest, your boost will be up.   In the NEO Head, being NA, you said it's stock, are you on stock cams, and stock springs in it?   Have you tried doing a run with the wastegate held fully open start to finish?
