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-
