Vehicle has an M103 engine - 1991 300-SEL
Some say oil consumption WITH blue/white smoke indicate worn Valve Stem Seals.

At 1st startup in the morning, after idling a min or two I see slight amts. of white smoke coming of the exhaust...white; not blue. This fades after warm up...no coolant loss at all.
I live in a high humidity area.

I know about the M103 guides/stems and oil consumption. What about this blue/white smoke issue? If the Valve Stem Seals were worn, would I see blue/white smoke ALL of the time or just at specific instances? Thanks for your time.
