Hi everyone-
When I start my 190E 3.8 it runs great up until it reaches about 85 degrees C. The idle then goes way down to barely running the car and the oil pressure drops as low as 1 pound when the car is at 90 degrees or higher. Shifting into park or neutral obviously solves the problem temporarily (still only goes up to about 2lbs). I don't want to crank up the idle because its already high when the car is is in park or neutral. The oil level is fine. Any suggestions? Vacuum leak? Air intake? Any help would be greatly appreciated.

Thanks, Mike

190 3.8 low oil pressure

Sorry for the late responses-

Guess I should've clarified... My 190E has a 1981 380SL motor in it. Custom job obviously. It moves pretty good. As for the oil pump question, I'd like to think I know a lot about mercedes but I don't know that question. Hopefully telling you exactly what motor it has will answer that for anyone. If a 1981 380SL motor has an oil pump, then yes it has one. Hopefully that helped... any suggestions now?

Thanks in advance-
