Smile Oil in air filter......

I just opened my 91 560sel air filter and saw alot of oil on it..I picked it up and it was heavy from the oil...any suggestions....I am also changing it tomorrow....

also when I start it up in the morning..I hear a lifter....and my mechanic said not to worry ...I also bought some $20 additive that may help it..

any help would be appreciated..

THE engine has a PCV orifice & sounds like that might be plugged.

It is where the rubber hose connects to the intake manifold from the drivers side valve cover.

IF the hose is disconnected & the engine is running there should be vacuum at that orifice on the manifold.

need to look at the inside of the cam cover. the factory sealant
cracks thus allowing blowby to go straight into the air filter.
check it out and reseal the baffle inside the cam cover.
as to lifter noise i would switch to mobil 1 15/50. might take a couple
of changes. if it still is noisy then you got a bad lifter or a bad
rocker arm/camshaft lobe. on all early v8's the cam oiler tube
holders like to come loose with age and don't allow full oil flow
to the cam lobes.
