Are you buying OEM filters? I found that the ones at Autozone were about 1-2 mm taller than OEM, so I did not use them for fear of the cap not sealing well and causing a leak. Plus, its just better to use OEM filters as far as I'm concerned. I don't thiink that it's worth the $4-5 savings for something as important as the oil filter.

The little plastic bag that comes with the filter should have the following items:

Large O-ring for the oil filter housing cap
Small O-ring for the tip of the long bolt that goes through the housing cap
Smaller copper gasket for the base of the long bolt that goes through the housing cap
larger copper gasket (only slightly larger than the other one) for the oil pan gasket plug

Replace all of these with every oil change. Again, it doesn't take a lot of torque for the long bolt to make the gasket seal.

When I did my first oil change on the E34 I recently bought, someone had not removed the previous gasket at the base of the long bolt. I removed the bolt and found two gaskets and silicone Took both of the gaskets off, cleaned up the bolt and cap and did it the proper way. No leaks.
Most problems are usually something simple !
