I Don't Think This Is The Correct Way To Install A Catch Can?

[jimmytim]

Hi all peoples,

I don't think this is the correct way to install a catch can....please advice!

Thank you!

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)

[jimmytim]

Okay...so if this setup works then I'll just leave it as is.

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

auto trans cooler? (just a guess)

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.

[2gceffy]

why do you need a breather and for it to go back into the intake?

i never knew there was a wrong way to hook up catch can..

someone care to explain?

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).

[bubba]

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

[CAT_SPEW]

Would there be much oil/gases going out through the breather, whether it's a filter or going to the intake piping?? Or is the majority caught in the can?

Looking at getting one myself..

Anything to stay away from??

[jimmytim]

Or should I run it like this?

connect between the two red points?

[blind_elk]

Yes. And obviously put back the hose joing the 2 rockers.

[WITTIES]

are u trying to catch cans?

oh snap

[jimmytim]

Yes. And obviously put back the hose joing the 2 rockers.

Okay, I'll do that then.

oh snap

Hahahaha!

[2gceffy]

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?...

[SECURITY]

they're there to catch as much oil as possible.
