Ultimate Breather Tank

Here is what in my eyes is one of the best catch cans I've seen for e46s. HPF also makes a very nice can. (500) This can will cost you about. (200) I took this idea from PEI. This set up requires a long tube intake. I realized after I made the mounting bracket. I had put a heater under my intake... I'm having some 94% reflective material shipped this week to combat that issue. Enjoy!

Instead of having it as a breather tank, why not route it back to the intake? So long as the catch can has adequate baffles and filters, minimal oil vapors will re-enter the intake track. Vacuum promotes better ring seal as well. Looks good though. Did you make a bracket for it to mount to or use an existing hole there? I ran an open crankcase breather system on my old turbo car so I do know it's effectiveness!






I'm using IMO one of the best bang for your buck cans. Made by 42 Draft Designs.

It costs $115 + shipping for the basic can and goes up from there. But this is the basic one:



And to show you the internal baffle/filter to catch oil at the top of the can.




Installed:

Looks very nice! M3's VC design allow for a lot more options, while still maintaining a clean engine bay. That is a very nice set up! I still hate the idea of having that hot air in my intake! The an fittings/hoses really drive up the price of a can. Thanks for sharing!

I did make a bracket to mount it. This bracket will cost about 4 dollars from home depot. You need to modify it slightly for it to work. I'm more than willing to go into great detail, about how I did it. Ask away! EDIT: BTW you have some very nice pieces in that bay!

At the rate my catch can is filling, I am thinking of using MrPaddleShift's solution that utilizes a BMW motorsport oil separator with a check valve, to drain back to dipstick

Ultimate oil breather = Dry sump system

Mine is filling up pretty fast. It actually doesn't fill up before the vapors start to blow out the other side though. I just need some baffling in there. I'm now using quart sized containers. But I'm venting out to the atmosphere.

Also, it is impossible to clean out the gunk. I would NEVER use something that I could take completely apart and clean. My lines are even clogging up with gunk.

My comes out with 1 wing nut and a turn of a hose. I used a big hose and mine doesn't seem to get clogged. But, I do have that nasty mayo looking stuff in mine. Pics/price of paddleshift's set up?

I was told by my BMW guru that if not setup correctly the catch can will create a vacuum strong enough to suck out ALL the oil in the pan. I am curious about the BMW check valve in a later post here please provide a link to the kit.

That's why a one way valve is utilized as well

Here's my catch can install and the alternative drain-to-dipstick method here

Wow, I really like the can you linked. Thank you

Anyone else did this install? Looking for ideals. Like to be super clean and not noticeable...

I'm sure I can help make a bracket or something/find a place for that thing. Hell, someone buy mine. I'll order this one and make a mount/location for it.
