Oil Catch Can project

Hey, I'm looking at adding a "Oil Catch Can" in line to help collect some of the emulsified oil/goo/sludge, that likes to form in our current PCV/oil separator system. There are some pretty knowledgeable people on this board who may have already done so. Your input and ideas are always welcomed.

Our Current system seems to have a high failure rate with multiple failure modes. In addition to the standard cold weather protocol, I'm also exploring a way to make our system more "service friendly." I would like a way to monitor it more closely. I know what causes the cheese whiz, (driving habits and and ambient conditions, etc), but I would like to be able to clean and/or replace the valves with out having to access a very difficult location on our M54's. Maybe a remote set-up on the fender wall? I know German Auto Solutions has had one in the works for several years now, but no product for release that I know of.

Edit: Just talked to German Auto Solutions. I will most likely be Beta testing their CCV Replacement product sometime in February if all goes as planned.Product will be bench tested first and then to beta testing.

I've been reading and pouring through threads all over the place about the CCV, or Oil Seperator system found on the BMW M54 engine (I-6). Not the easiest thing to wrap your head around on understanding the dynamics involved with the CCV, but I'm starting to understand that we don't have to live with its temperamental nature.

I have two M54's to watch over during the year, and more closely in the winter. I live in an unusally cold climate due to a geographic phenomenon called an "inversion". We were colder than the North Pole for two straight weeks last year.

If anyone wants to help or have input, feel free. You guys are great.

I know G.A.S has been working on the design for awhile now. Doru has poked them once in a while for update on bimmerfest E39 sub-forum

Subscribed. I get a pit in my gut every time I think of the sludge I see when pulling the dipstick or removing the 7l0 cap. My wife is the primary driver of the X5, and makes a lot of short, short trips, under 5 miles. The maintenance history that came with the car shows it's sucked oil into the intake at least twice in the past. And I sit on pins and needles...

Davintosh,
I thought I was the only one with a 710 cap.

Yeah, I know the feeling perfectly. I have switched over to "depends for men" because I'm afraid I'll lose control of all my bodily functions upon hearing the motor belch and hydro-lock with oil.

I have my wife trained well in her X3. I make her take the long way home and when it's good and warmed up, "give it a good lil spank'n" if you know what I mean.

I have one in the e46 (m54) and will be installing the same one/setup on the e53 (m54). This diagram is exactly what I followed and works amazing. My 330 was loosing oil. That ALL stopped once this was installed. Also the frequency you have to empty it, is not often. Actually I have yet to empty the one in the e46 since there isnt anything really to empty.


Link to tank I'm using: Godspeed Universal Racing Oil Catch Can Tank Oil Reservoir Tank Silver Color : Amazon.com : Automotive

I bought some heavier duty hose (nothing crazy) and again its been working great.

BTW you do NOT want a vented catch tank. Our motors must maintain crankcase vacuum

The 100 series.

Edit: I only suggest this if your crankcase pressure is higher than normal due to modification. Otherwise, the OE design works fine when maintained properly.

Dragon, looking forward to your beta testing and hopefully helping to get the GAS system to market!

When it does come to fruition id love to install Gary's solution, he does his shit complete with no shortcuts, and I'm sure it would be a very sleek looking setup when installed. When he releases it, I'll be one of the first customers, as peace of mind with the CCV is very important to me, and I'll also buy his DISA kit at the same time (I currently just have the new o ring)

With 71k on my X I have no records of CCV replacement, no paste thankfully. I replaced the oil filler cap last year and no mayo. My commute is just about 20 miles of highway driving so I'm right on the cusp of it being enough to not have condensate buildup. The last couple days worried me with the 0F temps, but I'm fortunate nothing bad happened.

Would like peace of mind for future winters however, I plan on having this X for years to come.

where do you mount this catch can and does it still remove moisture like the factory unit?

Now we're talk'n. I knew you guys have been holding out on me.

J.Belknap, did you run the mann-hummel CCV on your ride? I like the depth load filter they're using. I'd say that's a damn good option.

acpstunts, That's right on the money to where I was headed. Are there any draw backs to getting rid of the CCV entirely with your set up? I'm with you on running a closed system. I understand that if you vent to atmosphere you can induce ring flutter on the pistons due to pressure differentials, etc. NOT GOOD! Snap some pics of your E53 install and let us know how it goes.

RB, German Auto Solutions is the diggy bomb. I will be getting their Disa kit, Vanos seals, and Rad-Cap. If they approve me as a Beta tester for their unit, its gonna get a test at 8,000ft at Peter Sinks. It hits upwards of negative 60's (F) at times up there. It ranks as one of the coldest places on earth...... the worst place for a failure, but the best place to test it. My last X5 saw -46F and handled it like a champ. All in all, I'm a prime candidate for a failure due to my short trips to campus, with very little highway time. I just drive around burning fuel and making special high heat/speed runs out in BFE in an attempt to burn some damn cheese.

Peter Sinks - Wikipedia, the free encyclopedia

Here's a Pic of the micro-station and elevation profile.
