Default Replacing Oil Pump Seal?

so got my o2 sensor replaced at the dealer but the seal for the oil pump is leaking and its not covered under warranty.

the dealer wants, like 250 bucks to replace a 12 dollar seal?

no way, jose'

how hard would this be to do?
They said something about I might have to pull my exhaust off?

I am going to be getting a new upipe and downpipe soon anyway, so I might just wait.

anyone?

I'd be wary of them if they said they'd have to pull the exhaust to do it. You don't have to.

It's all labor really. You have to pull the timing cover and belt as it is located behind them. It's just getting to it that's a pain. Also, just be careful to seal up the oil pump itself when you reinstall it.

Won't have anything to do with your exhaust at all. You will need to remove the following:

Radiator
Accessory belts
Crank pulley
Timing belt covers (all 3)
Timing belt
Crank sprocket
Oil Pump

I have a writeup that covers doing almost all of this procedure until it comes time to remove the oil pump. It's pretty simple after you get everything removed, take out all the bolts to the oil pump (about 10 10mm bolts), and smack it loose with a rubber hammer. Tap out the oil seal from the rear side of the oil pump by using a flat screwdriver and hammer and going around the perimeter of the inside of the crank seal. Once it falls out, flip the oil pump over and lightly tap the new one in with the hammer. Clean off the mating surface of both the oil pump and block, apply thin coat of Subaru threebond (or permetex ultra grey) and reinstall. Be sure to align the oil pump bearing to the crankshaft "square" to get it on. Tighten it down nice and firmly and follow the timing belt change guide to reinstall the rest

It will get you all the way down to where all you have to do is remove the crank sprocket (it just pulls off) and the oil pump.

^Thanks

Oh, before I forget.. also remove the crank sensor (just 1 10mm bolt holds it in place on the top of the oil pump). And don't forget to put it back in place when you're all done.. not installing it means the car won't even start
