r129 oil smell

[wolfman]

A strange problem on my 1990 SL500. After about 10 minutes running there is a sickly smell of hot engine oil in the cabin. This disappears after a few minutes.
This repeats every trip....most odd. Had it checked by good Indie but no resolution.
Anyone got any ideas?
Thanks

are there any oil leaks? breather pipes split? and (silly question but ive seen it happen, and be missed) is the oil cap on properly?

Yes as above,, a breather pipe is off or split, you have breathing from the sump and from the top of the engine to the intake

Thanks guys....will get that checked again...it's just strange that the smell only lasts a few minutes and then disappears again for the rest of the journey...

probably due to the richer fuel mixture etc making more vapours for the crankcase to 'breathe' after a start up, especially a cold start.

Check the rocker cover gaskets, sound like oil finding its way onto the manifolds then burning off on cold start.
