Still in the process of rebuilding the front drivetrain and water pump/timing belt on the 99 LC. While tearing it all down noticed a lot of oil/dirt/sludge all over the oil pans and front. Wasn't enough to be dripping and no signs of leak on the ground, but enough crud underneath to make me want to find the culprit(s). After a lot of looking and not being able to pinpoint single source, decided to just fix everything while I was there. So besides everything for the timing belt/water pump, I pulled the cam and crank seals, oil cooler/filter bracket assembly, and both oil pans. After getting it all apart looks upper pan gasket was leaking and possibly crank seal.
So at this point I'm cleaning everything up and looking at this oil pump. The only item still left before I could just take out the 8 bolts holding it is the oil pump strainer. A quick search for parts and a new OEM Aisin is $68 at RockAuto - not exactly a high price for a critical part.
So all this said - is there any reason to not just go ahead and change it? What I mean is the factory manual makes it sound like hardest part is getting the sealant on right and torquing the bolts - is it really that simple at this point? And are there any reasons I'm not thinking of why putting a new one on is not a good idea?
The way i look at it this way I would eliminate any leaks they may be coming from it and oil pressure should be back to factory new.
As always appreciate feedback - Scott
