Balewolf Posted April 19, 2010 Share Posted April 19, 2010 I replaced my 2.2 in my Subaru (1997) Outback Impreza. I was running like a top, when all of a sudden, it started getting noisy. I purchased the engine from a mechanic who assured me she had replaced the water pump. I believe she was pulling my leg. There are no oil pressure problems, no rise in engine temps, but my gut feeling from where the noise is coming, that the water pump will soon fail. I checked the alternator and ac pump already and they both check out fine. Question is, while I am in there, should I look into replacing the oil pump since it will all be apart?

Legacy777 Posted April 19, 2010 Share Posted April 19, 2010 The oil pumps don't typically go bad. There is an o-ring between the block and oil pump that can be replaced, and you can check that the screws holding the oil pump backing plate have not backed off.
