Burger Motorsport Oil Catch Can 135i N54

[HP Autosport]

Keep Oil Out of your BMW 135i Air Intake System

It's no secret that the BMW N54 motor suffers from serious oil control problems causing oil to blow through and coat the intercooler and charge piping, gunking up intake valves and the VANOS system, lowering the effective octane, and generally degrading engine performance. The higher your boost levels the more apparent these problems become.

The solution to this problem has finally arrived. The BMS oil catch can. While there are other catch cans on the market they all fall short in various areas. Some are mounted on the hot/turbo side of the motor preventing proper vapor condensation. Others utilize hoses that are too small and runs that are too long to allow proper PCV ventilation causing internal motor / ring sealing issues. Some have insufficient or no internal baffle system while others have internal baffles systems that are too restrictive for the N54 motor. Most are simply repackaged oil catch cans from smaller / lower power motors shoe horned in to place in the N54 engine bay.

To solve these problems BMS designed their oil catch can kit from the ground up specifically for the N54 application. It features 100% CNC machining with zero welding for a precision fit and long life. The hoses exceed the OEM PCV piping in diameter and that flow rate is maintained throughout the entire oil catch can ensuring no excessive crankcase pressure buildup. The mounting location is out of the way under the cowl allowing for shorter lines, more efficient operation, and a very stealthy look. Install takes around 20 minutes, includes all required hardware, and is 100% reversible. Simply unscrew the base of the can to empty it's contents every 3-6 months.

I recently installed one of these along with DCI's from BMS.

Overall it is a fantastic piece of equipment. The finish on it is amazing.

I've only put maybe a thousand KM's on the engine since the OCC was installed, but it hasn't blown up yet!

The install instructions that shipped with my kit I think were for the V1, and I got v2 hardware as there were some slight variations on the install.

Fighting with the PCV lines probably took 10-15 minutes alone. So the 20 minute install time is a bit optimistic in my opinion.

Otherwise it's great, and I'd buy more stuff from BMS based on this piece of equipment.

I bought my BMS oil catch can a while back. Dealership did the walnut shell treatment on my 135 a few thousand miles back, and reading this post reminded me that I needed to install that catch can!

I agree about the quality and finish of the Berger oil catch can, it's as nice as it gets.

It'll be collecting blow-by oil on my car after monday.

I've also got one of these, not sure which version it is though. Install was easy enough, but took me about 40 minutes probably. One thing to note is that the cowl does not fall into place anymore as a result and has to be pushed down a bit and then screwed down. I imagine this is definitely worth it though, because in ~6K miles I did have some black goo that it caught. About 20ml at most, but that's 20ml less making a home on my intake valves. =)

Install time was 10mins for me. To allow engine cover to fit without rubbing on hoses, it is best to trim the rear of the engine cover(this added time obviously).

OT - catch can works well, install is easy, fitment is good.

Can someone please post a Youtube video of the install and how much oil is collected over say 1k miles?

Not a lot at all. I checked mine at like 4 months of driving and barely had anything in it. Just the walls of the CC had residue.

[shah269]

So did it do it's job or not?
Or is the car just not spewing any oil?

Hum...maybe you need to put a carbon sponge in there to see if it catches anymore?
Don't laugh...but the best ones you can buy at PetCo!
NO JOKE! They use it to clean the water for the fishes!

I dunno, I suppose. Maybe my car just isn't having as much oil blow-by as a majority of the others are experiencing . When I changed my charge pipe though to the ER one I had a decent amount of oil in there, was before I put the OCC in

Angerman, how much time do you spend above 4500rpm?

I have only eaten oil in both my 135i and STI during periods when I was autocrossing regularly, which generally involves using the ~4000-7200rpm band heavily, even if there isn't a lot of long periods of high throttle.

Even if I am driving in a "spirited" manner on the street I rarely run the car anywhere near redline (rarely exceed 4500), but even with a lot of throttle I don't seem to consume oil.

There are a lot of variables here, so I would not rush to conclusions as to the how and why of different owners report differently. Also, understand the difference between actually objectively measuring oil usage or buildup and the subjective reports you may see on internet forums. We have no idea if two people's ideas of "little oil" or "lots of oil" in different locations is really comparable.

Not a lot of time at all. I do a lot of city driving and usually shift before ~3000 RPMS or so. Every once and a while I'll do the occasional redline. I installed it beginning of June, so I may need to check it again..

[mike the snake]

The old style catch cans I've seen used a copper brillo mesh. Not sure about the carbon sponge.

I think the sponge would impede flow, which is not the best idea. RB for example says not to use OCCs unless it is a high-flow one, for e.g. this one.

As for the amount of oil captured, I would imagine it depends on so many things that it's hard to pin down why it's a lot or not, such as driving habits, oil change interval, type of oil, overall engine age and condition, etc.

I had kinda figured... If you don't run the car hard at high RPM you may not have a lot of blow-by and thus crank case pressure to push oily air through the PCV system.

I'll probably pick one up and see what happens when I start auto crossing again next spring.

[Newby]

We use one on our 1M race car, we just had 2x 1hour races + practice ( approx 2hours). All of which will see the vehicle at peak RPM constantly. There was about 15-20ml of oil in the can. All charge pipes + intercooler was oil free.

[shah269]

15-20ml of oil! HOLY CRAP!

20ml of oil can make a nice little mess when it heats up!

[New21er]

Just how hard is it to empty the container? I have the n55 so it mounts up front, but it still looks like a pain the unscrew the tank.

It just unscrews, like an oil filter. How is that a pain?

What I mean is can you easily un-screw the tank,or do you have to remove a bunch of stuff to get at it? It looks to me it would be hard to get your hand around the tank to un-screw it.

[Fed P]

Depends on how flexible you are, technically you can get at it without removing anything, but it's not exactly super easy. Considering that with my driving it will be like 10 years before I get 1/4 of it full, I'm not too worried
