1987 318 LA

Oil pump pickup screen do you guys have any advice on getting all the oil deposit out of it? I was thinking of leaving it in gasoline or diesel overnight to break it all up. Unless you guys have any advice?
rock auto! there is always something left...
Do you happen to have a part number?
i’ve got OEM 318 and 360 LA hydraulic rockers. I can look and see if there’s a part number stamped on the left right.

As for the oil pump pick up, it depends on what oil pan he has.
