I have a 1993 929 with 193K miles. Runs excellent. Just purchased. Love the car. Had a small oil leak and previous owner told me it needed oil pan gasket replacement. Took to repair shop, he removed pan, resealed with "goop," said no gasket is needed. Still leaks, but from another area. Yesterday, it leaked BADLY, as in most all oil out of the car within a few hours. Took back to repair shop. He put in "stop leak" for oil. Said it wasn't the pan, but another area higher up, hard to get to. Question: will this stuff work to stop the leak? Does the oil pan not need a gasket and is sealed by goop? If it's not the oil pan, what could it be? Help! I love this car and there HAS to be a cure for an oil leak, right? Any advice is much appreciated!! tt

 

Stop leak will take care of small leaks, not big ones. It's quite possible for the oil pan to seal up without use of a gasket (I use Permatex Blue for many gasket applications.) If you are careful and do it right, it works great. Although if there was a gasket on there from the factory, you should use a gasket. Sounds like you don't have a very good mechanic if his "fix" to a leak is a bottle of stop leak. I hope he didn't charge you too much for this "service". If the car is still leaking at the pan, get your money back on the work he performed as the work wasn't done properly (you took it in there to fix a leak, and he didn't fix it correctly) Use the Better Business Bureau as leverage if you need to.

I had a vehicle with numerous leaks. I had to track them down 1 at a time and fix them.

Best bet is to clean the outside of the engine as good as possible, then track the oil down to the source of the leak. There are glowing dyes that you can buy to add to your oil to help you track the leak. After the engine is clean and dry, put the dye into the oil and let it run for a little while to circulate the dye. Then turn off the lights in your garage and hit the engine bay with a blacklight, the leaks should glow.

 

I see you from the bus too where did you take it man Ill check at work today if your car came with a gasket or not your machanic sounds like a moron anway

 

I would think that if the oil leak repair done by that "mechanic" made the problem worse, I would think that was the majority of the problem. I do agree with the stop leak statement above, don't have that person do any more work. There are many more seals that can leak, some are, rear main, front main, cam seals, valve covers, and misc o-rings to start with. DO try the dye as stated above after cleaning the engine.
