Oil pump replacement question
I was wondering if someone may be able to let me know if it is possible to change to oil pump in a 2001 silverado 2500 4x4? I have a 01 with 366,000 miles, the oil pressure tends to be fine then drops off then comes back up. The sending unit is fine, so ive been advised that a new oil pump in in order.
Any help would be apreciated very much.

have the same issue and my mechanic said not to bother with the pump, that with high mileage its more then likely its a bearing within the engine that is allowing oil to get by, he said as long as its holding decent pressure when driving, not overheating, and no metal in the oil not to worry. He did say that if you do want to change the pump you have to remove the front drive shaft and any tranny or oil coolant lies to get the oil pan off99 K1500 Suburban LT "THE BEAST"

probably not the oil pump. I've just gone through this myself. My motor had 150k miles and low oil ressure. Swapped a high-flow pump (not a small job there) and no change.
Old motors wear out mains and just don't hold pressure.
I ended up swappung in a new motor with 10K miles and oil pressure is a-OK.
No cheap solution there.
