[12Ounce]

The oil filter screws onto the oil pump. The oil pump is attached (by six bolts) to the "front cover" of the engine. The two bolts furthest apart are installed with 10Nm torque... the remaining four bolts with 25Nm torque. There an "o-ring" of sorts between the pump and the cover. The pressure relief valve is part of the pump (I believe).

You may want to look at a replacement pump ... probably avail at AutoZone or NAPA.. before removing yours, just to see what's what.

My reference is a '99 3.8. I would think the oil pumps are the same on both models.
