Oil catch can on gc8? engine pissing out oil!!

[whatchain]

so i had a bit of an incident on the track today. after a few hard laps. i came into the pits and opened my bonnet to discover oil all over the battery, fuse box, bov, right side of bonnet, right side of radiator, brake master cylinder and a few other lines. a few guys then came over and was trying to find out find out what happened. in the end, one of the guys who turns out to be a bit of a subaru wizard thinks i might have been "cornering so hard" that some of the engine oil managed to make it's way from one of the breather lines on the sides and into the intake system, it then ended up going through the intercooler and was spraying out of the bov!! . Didn know such a thing could even happen. just 1 thing. Has this happened to anyone before!? i was told i should consider getting a oil catch can and this is suppose to stop this from happening? i was shitting myself for a bit as i didn't know wtf happened! lol

yes thats exactly what happens, and yes you should run one - but beware - the catch can fills up and they still spray everywhere ;D

I would give your intake and TMIC / FMIC a good clean out to rid of the oil. It drops the octane rating badly and when raping your car will do lots of damage

thats EXACTLY what i was told lol. that is rather disappointing especially from a Subaru. atlease it was nothing major. i usually shit myself in situations like that as im not really mechanically minded! lucky it turns out it was a design flaw?

[funkytown]

its a 'feature' of a horizontally apposed engine. with lateral G forces as we have heads in the same plain (almost) as the bottom of the motor its very easy to trap the oil out in the heads, and it comes out the breathers if you keep the lateral force up.

Most other engines the head is that the top so no issue. If you can design a boxer motor that doesnt shit it self on a wet sump go right ahead

[whatchain]

hmm i see. ok, so what and how do you suggest i use to clean the ic? would water do or i got a can of wax and grease remover. would that also work?? also is there any brand oil catch can/tank i should look for? or they all prety much the same?

[sl8r]

I reckon the catch can setup (aka spewing) on mine caused me to do my BEB. Yay for subarus

[funkytown]

water... seriously...???? since when to do water and oil mix.

Get yourself something like petrol and put some in your intercooler and shake it all about and drain.

A can is a can is a can. the size is important and the teeing of the lines to it. about 2L minimum id suggest.

Which track were you at?

Baffled sump is the solution?

[sl8r]

nope, helps but not the solution. you need to recycle it back into the car quickly or simply block the offending head (dependent on track)

like i said funky, im noob with this sort of stuff.. i was at the motosoc track day in ruapuna. saw Flat4 there aswell.

[funkytown]

sorry but any noob knows water and oil dont go.

Petrol will dissolve / dilute / clean the IC.

[sl8r]

re can sizes etc - check your motorsport manual as there is a perscribed size you are allowed to run depending on engine size.

Fully cannot remember (got mine ages ago) but i think minimum is 1l for a 2 litre motor (check manual). Baffles in the can is also a good thing. I got mine from sinco customs - good price high quality.

hey funky, what about the oil that went into the turbo inlet and throttle body? do i need to clean those out too?

[funkytown]

some upprr engine cleaner would be the go for manifold. and towel out what you xan on the t/b.

if you want to go to the hassle of pulling turbo off and cleaning the compressor out it definately wouldnt hurt..

mean. thanks for the info people.
