Stupid oil filter question-E420
Ok, I have changed oil several times using topsider. Recently looking at new oil filter package and besides the 2 o rings or gaskets that go on the filter cover housing I have a small copper washer.
Is this washer for the bolt that goes through the filter housing cover or for the drain plug if you drained the oil from the oil pan?
