Any time, Absolutely any time you drop and or replace the oil pan you should check the main barrings and replace the oil pump, even if it is working fine.If I replace the lower Oil Pan in my car, is it also a good idea to change the oil pump?
in the real world the oil pump is never bad.what it's get bad is the oil pressure release valve and/or the gear in the shaft of the distributor.





check the ball and the spring on the pressure release valve of the pump.
Oil pan removal/installation has nothing to do and should not affect operation of the oil pump. First of all, most vehicles don't even have oil pumps in the lower end, and all decent ones have pumps incorporated in the timing cover. Well-built engines provide pump life exceeding that of the rest of the vehicle. If what you are talking about is of a different kind, replace everything once you get access to it.
For what ever reason you are replacing the pan, unless severe damage was done, you don't NEED to replace the oil pump, But as I have rebuilt many engines, I have taken the precaution to replace the pump when i have the pan down, for the minimal cost it is great insurance..
it is good to be salf than sorry
most mechanics especially shade tree mechanics like to change this part at the time that they have the oil pan off. this is because that way you only have to change the oil pan gasket one time. and it is not really that expensive and is the only other part in there....just lessens the possiblity of taking it off again....not a must but a why not...
depending on the year, it wouldnt hurt to check prices out. In mitsubishis, the oil pumps like to seize and then your engine is gone. Just simply changing the oil pan wont affect the pump.
if your going to change the oil pan,you dont have to change the oil pump,butit would be a good idea to,for all they cost.just remember to pack the new 1 with petroleum jelly,so the pump will have something to prime itself.
