Anyone using an oil catch can?

All I can find is universal kits
The only bit that would need to be specific to the R8 would be some hose, which I would imagine you'd be expected to sort yourself as it's just some rubber hose.Gurmeet (gsd2000) got the catch can I'm using, on a Monaro, but it's by no means Monaro specific, it's just a can with a straight arm that bolts to the cylinder head.

Mine's a UPR one, but I had to make a bracket to fix it to the end of the head.
Are you FI? I'm finding NA I've caught sod-all...but at least it's not lining the intake I guess.
mine is vented to air as I need a 1 way valve that fits. Are you FI? I'm finding NA I've caught sod-all...but at least it's not lining the intake I guess.
But it's caught about 1mm of oil in 2 years.
The problem with catch cans is that they will only catch oil that has condensed. Even NA over time you will find that the inside of the intake is covered with a film of oil. This is the result of the oil vapours that come from the crankcase, condensing.
All the catch cans I have seen (which are simple plenum chambers) have NO way of coalescing the vapours which will still get through.
Catch cans work to an extent, and the problem is much worse with FI, but will not completely cure the problem. Which is, that any oil retained in the mixture will drop the octane rating and thus performance, and the oil film will prove a drag on airflow.

cheers guys. Anyone that was on the run last week would have seen that I'm putting out some smoke on the overrun! so thought I'd get it checked out and was told to try a catch can first, he explained that with the smoke on the overrun that this could be the best thing to try first. He warned me though that most of the universal kits are not baffled and do f all, so make sure you buy a baffled one, just asking if you guys have any that you'd recommend or have fitted already that work well?
Mikey, where did you get yours from?

I had a dual Saiku Michi can and it caught quite a bit of oil. Then again, I had a bit of blow by to begin with. Now I run a Mighty Mouse race can vented to atmosphere from both valve covers and eliminated the factory PCV.
I seem to be in the same position, where did you order your cans from?MyM8V8 said:

Mine has the top half packed with coarse wire wool type stuff (optional extra) - hopefully that goes some way to pulling the oil from the air. I did wonder if it causes too much of a restriction, will have to remember to try blowing through it some time.

Have you not considered a vac pump, especially on the 457?
