I've got a 1993 940 n/a. I must have over tightened the oil filter last time I changed the oil because now it won't come off. I never use the filter wrench to tighten new filters so I don't have a clue how this happened. To make things worse I managed to crush and tear holes in the filter with some channel locks. It's wedged between the exhaust manifold, a motor mount, and the power-steering pump so there's no room to get to it. Anyone have any ideas on how to get it off?
