[T3] Oil cooler seals.

Yes I know you were talking about the strainer, Mine didn't have issues
with the strainer holes it comes out easy. I was talking about after I
repaired the sump plate it fit on with a slight push and stayed there.
Everytime I removed it including this time I had to hold it or it would
fall off and hold it putting it back on. I would leave one nut on the plate
while the oil drained out then when it was just drips remove the one nut. I
guess I'll know the next oil change if it will drop or if I need to wiggle
or pry it off..
