Oil Squirting Out Threw The Dip Stick !

far out man :s how much set u back get it fixed??

Why a catch can when you got no blow by Daz, I only fitted mine because I was sick of the oil through the intake and cooler.

[Kroozin]

I wouldnt mind doing the catch can mod soon too.. I'm led to believe the oil thru the intake sys. may knock your octane around a tad in some cases + the intercooler may get tackier inside than if there was no oil breather at all going to your intake before the turbo.. I dont really know could be horse sh*t too + off topic

[Henz]

I've heard the octane thing too. I will fit one eventually just to tidy everything up.

Enough oil going into the intake will knock your fuels octane back. So if your getting enough blowby its definitely a safety measure for the engine.

On my turbo ED Falcon I have two catch can set ups. One for the PCV side which prevents oil going into the inlet and retains the PCV operation. The setup is identical to factory except there is a sophisticated oil catch can setup between the PCV and inlet manifold.

Then there is another catchcan on the breather hose. Except my breather outlet side is using a 25mm hole which goes to the breather catchcan and can either vent to air or in my case plumb back into the turbo inlet.

Both catchcans drain back the caught oil back into the engine on shutdown via one way valves. And it works, no oil anywhere where it shouldn't be.

So for a built high boost high rev engine I would say the stock breather hose is way too small and most of the increased breather hoses sizes I see people using are still too small.

On a turbo 202 I have a large breather (about 38mm dia), cured oil leaks as at 25psi and 7000rpm the engine will pressurise without an adequate breather.

On my FG I will duplicate what I did on my ED as I noticed looking down the throttle body that there is a puddle of oil in the inlet manifold from the standard uncatched breather PCV system.

[Never had any say Panda]

Kroozin not sure about XR6T's but I know before catch can my old WRX used to build up a heap of oil in the intercooler.. I had it off a couple time soaking in kero to clean it out..

@ turbotrana, how and where does the oil feed back from the cans. I understand the 1way valve so probably isnt anymore to the how.

Also search on google for grimspeed aos, I was thinking bout this as opposed to catchcans. Meant to work same but without the cans, its made for subaru but can probably replicate it for the falcon. Just cant decide if its good idea compared to cans.

Nothing cause it wasnt my fault but we pulled the engine out & put 14mm headstuds in with copper gasket so on & so on so it wouldnt happen again.

The BMW E39 6cyl has a factory catch can (made out of plastic though) that filters PCV oil. I have never had a detailed look at it but know its there.

Its a tube that goes from the bottom of the catchcan to the sump and its got a one way valve in there. On vacume it closes up, on shutdown it opens up. But then you also got to have a one way valve from inlet manifold to catch can (under boost) and also I put an extra one from catch can to PCV. I just use the BA turbo plastic one way valves.

In the middle ring I stuff scrubbing pads so the oil travels into the outer ring then thru the pads then into the centre hole to filter the oil. Done this style a few times and works well

Just shows fitting. The one on the side is the entry. One on top is exit and the other one drain.

Hope this helps. I have always spent alot of time on controlling the oil in engines but always with emissions and detonation in mind. It just pushes that detonation threshold a little further.

The breather side works on gravity and located next to the rocker and is a completely different setup for another day.
