I removed the Scotch Brite pads because they were holding oil. The brass filters work much better - they drain easier. Off the top of my head - I think this system was installed about a month ago.

Makeshift catch can idea:
Attachment 143013
Parts needed;
4 - Brass Fuel Filters (Carquest #86050 $3 each)
10 - (1 inch) hose clamps
2 - Brass T Fittings - Home Depot (SharkBite 3/4x3/4x3/4) plumbing dept. $4 each
1 roll - Home Depot (Watts 42143912 7/8x5/8x10 ft.) plumbing dept. $10
Approximate Total $40
Note: Clear hose will be easier to form when heated with a hair dryer.
The clear hose appears to hold up well, but I do not live in a freezing climate. The clear hose allows you to see what's going on and the non-corrugated hose allows for better oil drainage back to valve covers. The brass filters are a first and secondary line of defense against oil and they breath well. The U-shaped trap from right to left T-fittings (ran under fresh air intake) act as a catch can. It also appears to have equalized the vacuum between both CCVs because I get almost no oil caught. (Maybe 1 tablespoon & oil level on dipstick is not moving) Allows for engine covers to be installed.

I have a N62TU which only has an upper intake port (one tube assembly - T'ed off to both CCVs). For those of you with the early style 2 hose system - just be creative, but keep in mind the oil will want to flow downhill - don't let it flow towards the intake. You could probably cap off the lower port then just copy my install.

Thats what ill do is cap it off . I was just thinking if the amount of vacume will be reduced if I tee it off .. Vs each ccv having its own inlet ,,and not functioning properly due to a lower amount of vacume per each ccv . Not sure if they both would work as designed with two ccv on one inlet. But then the 550 is like that ..

The CCVs should be the same as mine - You can check the vacuum at the dipstick after the install to verify - $40 in parts and an hour of your time is worth a try.

The vaccum isn't excessively high - it's just an inadequate crankcase vent system, the OEM tube assembly doesn't drain well and the intake acts like a catch can.

When I pull the oil cap off my car, it starts to stumble and eventually dies. Is this normal for other N62 owners? Mine in particular is a 04 545i. Thanks for sharing your catchcan creation.

I can pull my oil filler cap (makes a mess) or my dipstick and it does not effect my engine idle. This tells me that my CCV diaphragms are sealing well with adequate intake vacuum.
