1994 Buick Park Avenue Question: what do you remove to gain access to the oil pump
Answer #1Superbob October 11, 2010, 17:35Master
The engine bearings or oil pump may be worn out. The oil pump screen may be clogged, also. If the engine has a lot of miles or has run on dirty oil, the oil galleys may be blocked. It may be a good idea to drop the oil pan and check a bearing or two to evaluate the engine wear.

you have to remove the oil pan and the pump is located there.
