Oil breather/swirl tank necessary?
I've been checking out the pics on here Engine Pics Wanted-Needed
and have noticed some people are using swirl tanks/overflow tanks while others (like Fishcop) are just going to a breather filter.   Is a tank necessary? This is a track-only car if that makes a difference... thanks

john
i think randy has hit the nail on the head. CAMS rules specify a tank or recirculation via the air cleaners - from memory the tank volume is based on engine volume. i had an AL tank attached to the rear cross bar when i had webers. i'm now using MFI and the stock recirculation setup.

Bird. It's the word...

I'm a rebel and don't play by the rules!
In all seriousness, it's been just another of the things I've got to get around to doing... I've slipped under the scruitineers radar a couple of times - bound to get caught eventually

it'll also save you from blowing oil droplets all over - prolonged high rpm's will do it.

Thanks again guys. Those "Stefs" cans look great...I suppose I'll do a search on the downsides of having oil and vapors venting into the intake (as the street cars are plumbed...)
Hey Randy, my FJ40 never needed a can, but then again I guess 3800 rpm redline doesn't really qualify as "high revs" does it!

probably not -- but the design of the valvetrain & etc. would affect things too
there are some threads on this if you search

Am I missing something on this? Do all porsche 911 cars blow oil at high RPMs? Thanks all. Eric
