have an 01 525i built 5/01 ,recently had some white smoke coming out of exhaust right after starting comes out like a fog machine, this has been going on for a week now, not driving the car ,doing some research. we pressure tested radiator and did a chemical test on coolant and no mayo on dipstick and filler cap, so that eliminates blown head gasket,
my suspicion is the ccv / oil separator , I remove the air intake and see a lot of oil leaking
on side of engine, must be coming from oil filter housing ( common with the e39) . i just remove the adjuster unit on the intake manifold and whoa ! manifold is soaked in oil. if the oil separator goes bad , would it send oil back into manifold causing it to burn in chamber ? (also check the spark plugs and they are black from oil burn no other dis-coloration).
I need a second opinion by concluding that it is the ccv, thinking about ordering parts now.
need help
