Smoke on idle with suction at oil filler. OSV exist on an N62?

[Bulk]

Hey guys,

I bought replacement Valve Stem Seals for my N62 but haven't had the will to replace them yet. I thought I'd try one last time to do something else instead as it only seems to happen with new oil.

I've seen the video with the crazy german replacing the OSV on the M62 but I don't know if there is an OSV on the N62 or just the 2 Crankcase valves.

I replaced the Crankcase valves a year ago so could they be bad again? or can bad Valve stem seals cause that amount of suction at the filler?

Should I try something as simple as running the oil level towards the low end as opposed to the high end of the dipstick?

i have the same problem. Replace the ccv valves and it will go away a bit. The problem is the sludge. See this thread and check my response..

Yup changed those a year ago, could it be possible that they've gone bad again????

Of course. Don't worry. I also changed mine a year ago and now its time to change then again. I actually have them both in my back seat.

Did you ever find the answer to that?
