Question about 1995 Buick LeSabre
HI, This may not be much help but I have a 1995 Buick LeSabre 3.8 engine with what sounds like Exactly the same problem. The leak looked like the oil filter was leaking, Then I saw it was not that it looked like the adapter was the problem, I replaced the adapter gasket -- no change. Then I thought the leak was maybe coming from above and seeping down the side of the timing chain cover to look like it was the adapter. I replaced the valve cover gaskets, the upper And lower intake gaskets. No luck. Then I replaced the timing chain cover gasket --with no small amount of labor, and the damper seal, and the oil pan gasket and end seals. The leak stopped.... for about 200 miles, Now its back . Slow at first but getting faster. Sooo.. that is where its at right now. I am beginning to wonder if there are better aftermarket gaskets out there for GM. If you came up with anything I WOULD SURE LIKE TO HEAR IT... By the looks of these ultra thin gaskets they seem not up to the job. BTW in addition to the new gaskets I used a small amount of silicone sealer too. Maybe when the next gasket goes in I will use the good old fashion black Parma Tex Messy but good stuff. Well good Luck. PS. the sending unit is ok. firstname.lastname@example.org
Have you checked the pcv valve and hose to see if motor vacuum is venting the pressure if not press. will build - could be causing your gasket leak problem?

I have the same problem and replaced gaskets and even the oil filter adapter.The car stopped leaking about 1 month and gradually started poring down my carport.I googled the problem and there is a "DURA SEAL" as seen on TV.It's expensive but may do the trick.It may work long enough to get rid of the pile of junk(GM) stuff.LOL
