Oil Catch Can installation?

[apeman69]

10mm inside diameter piping to fit to the nipples on the car. Get a catch can with 10mm connectors for the simple life!

what size catch can should i be looking for? is there a math to this? i see some from 0.5 litres to 3 litres lol.. thanks!

[jayp]

It all depends how often you want to empty it, I have a half liter in mine and still have not emptied it in a year, but it doesn't seem to fill up with oil, get some nasty water in there tho, i assume condensation from the crankcase. It's down to space restrictions as well

Nice installation, I can't help noticing that you are still venting the front rocker cover into the front 3 cylinders via the PCV one way valve. Its the small hose in the back centre of the front rocker cover. You won't pull oil vapour under load with boost but you can add some oil build up to the intake which can pick up again when you accelerate as it has already passed the PCV valve. The oil vapour could cause octance problems on the front cylinders. Block off the mainfold pipe and vent the PCV valve to the catch can too.

Nice 1 Barry
I found mine in a box in box in a box today, while sorting out garage. Must get round to fitting it Only had a "Few" years

Some photos from fitting oil catch can.
I bought this one
http://www.ebay.co.uk/itm/1708569919...84.m1497.l2648
but they are quite big and it is hard to find room for it without running long pipes,
so decided to make it slightly smaller with added pad for better oil absorption.

Might put a catch can in soon but do I go with 9mm, 15mm or 19mm hose fittings?

[wintertidenz]

9mm fittings. I used some 10mm fuel injection hosing for mine and found it was slightly too big, so 9mm should be about right.

[Oblivion]

Ok 9mm sounds like a plan then, cheers!

jjust thought i would add to this thread.
as fassi1 pointed out above most oil catch cans come with nothing inside, just an empty box.
this makes tham about as useful as a chocolate tea pot. the oil vapour goes in to them and get sucked or pushed straight out. you might as well not have one fitted.

you need to put something inside the can for the oil to condence on to when it enters the can. i use stainless steel pan scrubs, ( you can get 10 for £1 in pound shops).

but you have to ensure the oil mist vapour goes through the condensation media (read Pan scrubs) so you need to add a pipe from the inlet port on the top of the can to near the bottom of the can so the oil mist vapour has to go through the condensation media before it exit the can back up at the top of can. if you just add the condensation media there is nothing to stop the oil mist from entering the can at one port at the top of the can and going straight out the other port at the top of the can.

i hate to think how many people are rumming with just empty catch cans thinking, i never have to empty this can my engine must not produce any oil vapour, the when they look at the post turbo inlet pipe work it is covered in oil mist vapour and they think there turbos seals are leaking.because they have a catch can fitted and that would catch any oil mist from the engine, DOOM and GLOOM new turbos required.

please please please check you catch cans and make sure you ad the pipe and the condensation media. It will take 10 mins to chack just undo the 4 screws on the top of catch can and pull the lid off to check.

Very good point dave i know the one i had fitted on my evo had wirewool inside and had a removable top so it could be changed have looked at a few as i need one for the vr4 but as yet its on the todo list

[Humpty's Revenge]

i know the one i had fitted on my evo had wirewool

Condensation = moisture = Wire wool rusts.....

Put stainless steal kitchen scourers in the catch can, then it will work spot on...

[Oblivion]

Just wondering if it is fine to vent the return pipe that comes out of the catch can to atmosphere or does it have to go into the pipe after the maf?

Also I dont supppose someone could elaborate on this perhaps with a pic/diagram? I cant get my head around how this part supposed to go together!
