oil smell

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?:confused: Thanks

Hi All, I'm having a repeat problem with my CLS and was hoping someone may be able to offer me & my local dealer some guidance or further ideas into what the cause may be: Symptoms: Engine runs slightly 'lumpy' Gear changes 1/2/3 are harsh (not as smooth) Engine appears to be running...
