I've got a 1990 CQ and its got an oil leak, seemingly from the gasket. On autopartswarehouse.com there are two or three different kinds. The one OEM one costs $40 and requires two, while the non-OEM ones are like $17 and don't say anything about needing two. The $17 ones also look just a little different. Any ideas?

check other sites too and parts stores or maybe ask a dealer

look under the car and see the shape of your oil pan, check with napa if they made oil pan gasket for your car. they have the silicone ones, better then cork screw one.

heyy forgot something, this might save u some money. first try this! try tieting in the bolts of your oil pan, In time they get loose. that might be the problem? Dont over torque it, dont want to strip the screw. Use hand tools. And then see if it leaks. If it does then replace the gasket. tell us how u did?
