Howdy all!

I wanted to share my latest DIY, ESPECIALLY with the "gotcha" that bit me right off. I know say this a ton in the video, but my crank case hose was REALLY fragile and checking the inside of the hose insulation, had been cracked and leaking for some time.

I wanted to start to reduce the oil build up into my valves, so installed the BMS oil catch can today. Easy, simple, and can head off or slow down more expensive walnut blasting or chemical cleaning.

Yeah yeah yeah, saying it again, make sure to check the health of the crank case hose BEFORE you break it, and your car can get you there and back for a replacement. For a laugh? My stealership wanted $78 for it when I first called.. uh no.. try again.

Any questions please let me know!

Did mine this weekend and that damn thing shattered into 5 pieces in my hand. Was not forcing anything just cheap crappy pipe used by BMW. Fixed it up with a new hose and good to go.

Good video, watched a handful of yours before....

I'll preface with this, bms makes good product. This catch can is no exception. Good quality can and hose, and reusing the stock hose is ingenious. The problem is this doesn't fit on the f30 chassis. Only the f32. They do have it marketed for the f30, but i bought one and it doesn't work. And they know about it.

So if you have an f30 and thinking about this mod. Don't.

Fit fine on my F30. Just had the issue with the brittle exploding hose.

Really? What part of it doesn't work?

Seems like I should consider replacing that as soon as possible for my 335i. I somehow broke one of the 4 plastic clips for my GF's X3 35i.

Been wearing this can on my F30 for 42k miles.

First mod.

*laugh* Well funny to hear I am not the only one with the hose just exploding.. I was AMAZED on how it just cracked and shattered once I had it off.

I am guessing replacing that should be a regular maintenance kinda thing.

The oil cooler lines on mine completely block it from sitting far enough back to use the mount. Both mine run to the front of the car, where others have one go to the front and one towards the rear. My car is a late 2012 build date, 2013 model year.

Thanks for posting up the DIY. On my previous vehicle (2015 392 Challenger) this mod was a must. From what I've read through various posts, it seems some people believe a catch can isn't necessary on the N55, while others do.

Curious to see if you think this is necessary or just added it as it "doesn't hurt"

Little bit of both candidly.. definitely know folks who have cleaned their valves on the N55. Granted I am now 60k in so lots of miles for residue to already be there. This is such a simple and obvious mod I thought it couldn't hurt to do so.

Plus.. found that leaky crank case hose. lol The funny thing is the car honestly sounds different after that hose replacement. Drove the car for an hour after the change, and gut feeling the whole time it sounded slightly different. (not from the can, but the new hose) Cant put my finger on how, but something.

Everything I've read (do a Google search of "BMW N55 walnut blasting") says the N55 doesn't suffer from significant oil build up on the intake valves and that many that have peered into the heads, have seen marginal build-up after 60-80K miles and shops are recommending 100K blasting.

The N55 is nothing like the N54 in terms of this common direct injection issue.

I'll be curious to see how much oil you'll be capturing.

Here are pictures of a N55 135i with 75K miles prior to and after walnut blasting. There's not much of anything on the exhaust valves at 75K. https://www.1addicts.com/forums/show....php?t=1437656

I will have my intakes off in likely 3-4 weeks for my HPFP install, and will get a good look at the valves then for sure.

FWIW... the N20 catches this much every 5k miles. Definitely a much different substance than my last motor which was also DI but NA rather than T.

I can speak for N54 but when I attempted to replace my charge pipe yesterday, I noticed there was a lot of oil on the map sensor. Is that normal?

My N55 is pretty much stock with 26K miles...

Interesting.. definite "a lot"? I definitely found residue that I could wipe off with a finger when I changed my CP. (pre catch can)

Damn that is just disgusting! I will post up info on what I catch the can as well.

Umm there was a solid drop on the metal contact in the middle, and the plastic casting below the o-ring was wet. Not like the thing was dripping oil, but definitely damped...

I ran into that same fitting issue in my 2013. I eventually squeezed it in there when the lines were warm and pliable. Hopefully I'm not putting undue pressure on the lines by having that can in there.

Are you guys mounting on the drivers side or passenger side of engine bay?

Passenger side. You can sorta see the lines below the can in this pic. It is before I got it to fit.

Thank you for the Video

Definitely where its supposed to go. Also the bolts on the core support don't fit into the occ mount bracket. The torx bolts work, the others don't.
