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.

You could probably cap off the lower port then just copy my install.[/QUOTE
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 ..

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.
