I don't want to hijack this thread more than I have so I'll answer succinctly as possible. No and zero. None of of bimmers burn any oil between changes.Any metal wools or bird nest inside the catchcan? How is the oil consumption since zero oil caught and drained back?
maybe it was but it could have only went in one way it threaded into the catch can. I put the first pcv valve I had originally put in and so far so good. With no pcv valve at all I had a horrendous squeak at any rpm.Is the check valve installed backwards on your catch can system?
I just drove about 30 miles with my new catch can. Burning oil smell, then yellow oil light (yikes) told me to pull over. Oil everywhere, looks to be valve cover. I do have a PCV inline, but the extra vacuum seems to have sprung a MASSIVE leak. I have added 3 quarts of oil and it still hasn't...www.e46fanatics.com
OP, have you tried the bag over the dipstick tube?It depends on if CCV is stock or home brew, and working or not. You might have a positive pressure crankcase instead of negative with a working stock CCV. Cover the oil dipstick tube with an empty plastic bag tight, and see if running engine will suck the air out of bag or add more into it.
Did you connect to manifold vacuum or to the distribution piece on top of the manifold?I have not done the bag for not due to the fact of at idle if I took off the oil fill cap, I had to pry it off almost with how much crankcase vacuum there is.
M50 manifold converted, no distribution piece, and all engines have cc vacuum at idle and when under accel it should be neutral.Did you connect to manifold vacuum or to the distribution piece on top of the manifold?
I'm curious, why do you guys believe that driving around with that much crankcase vacuum is a good thing?
