bmw 320i oil pressure
I have a 1978 bmw 320i that sat for a year and the oil pressure won't go above 6 or 7 pounds even when revved. The gauge and sending unit have all checked out so next I pulled the pan to check the p/u screen, and to check the clearances on the oil pump. all were ok. bypass spring was also the correct length and was not sticking. I pulled a main brg cap and the bearing had very little wear on it. I'm stumped, I know there is oil getting to the top end because you can see it splashing around with the cap off. any ideas?
