1995 3.8 oil leak at oil filter area still leaks

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.

    I've had the exact problem and oil is running down my carport as we speak on this sight.The only thing I know to do is to buy the expensive "Dura Seal" as seen on TV until I can sell this pile of GM junk.I guess the only advantage is no new car payment and hoping it doesn't throw a rod !

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

I just got an oil change less than 3 weeks ago and today my engine starts knocking and my oil light is on, could that be a bad O2 sensor?

No Bad o2 But Check oil Level. How old Was The oil That Came Out? Fresh oil Will Clean Out Sludge Deposits If The oil Was'nt Changed In A Timely Manor It could Have caused leaks. also Check Drain Plug Gasket for leaks And Make Sure Oil Filter Is Correct And Tight.

I recently got a oil and filter change now i hear knocking noise

If the oil has been changed, why are you putting more oil into the engine? Does the engine use/burn oil, or have an oil leak? If you have none of these problems, then you may be overfilling the engine which is just as bad as no oil.

Need diagram of engine to replace fuel filter on 1995 Buick LeSabre

The fuel filter is located inside the frame rail, just ahead of the passenger-side wheelwell opening. It has a threaded fitting on the forward end, and a quick-release clip on the back hose attachment.
Caution! The fuel is under pressure. Wrap a rag around the quick-release fitting as you release it, to catch any spray. or first relieve the pressure at the test port on the injector fuel rail (under the plastic engine cover), again using a rag to catch the fuel spray. Wear safety glasses, and only do this when the car is completely cooled off. You WILL spill some fuel while doing this, so have a catch container, and/or spread oil-dry/cat litter on the ground under the filter area. After changing the filter, turn the ignition "on", which powers up the fuel pump, but do not start the car. Now check for leaks at the filter, and at the test port, if you used it to bleed off fuel pressure. If everything is dry, you are OK.

Oil leaking on front right side of the car near oil pan and oil filter

You need to clean the engine and then run the vehicle while watching the area. The most common failure is the oil sending unit located near the oil filter. I have also seen a leak develop between the oil pump housing, which is mounted directly behind the hamonic balencer and the engine block.
