2000 Saturn SL2 oil pan

Can I use "stop leak" as a temporary fix for a leak in my oil pan? I have the new pan, but my son can't fix until next weekend. Want to stop at least some of the leaking without damaging the car
Do you
have the same problem?

How bad is the leak and why is it leaking? The only products I'm aware of are seal conditioners to return rubber seals to a pliable condition. They don't plug up holes, and you don't want anything in there that could plug one of the many tiny passages. That could do more damage than running the engine a little low on oil.

New oil has the same seal conditioner additives in it along with corrosion inhibitors and detergents. Regular oil changes replenish those additives, which wear out in about 3,000 miles, but sometimes changing brands of oil can start or increase oil leakage. That's due to one brand's additives being not compatible with those of another brand.

If you have a small hole in the side of the pan, due to rust, you can do a temporary fix with RTV gasket sealer. Wire brush the area, then coat the hole with the sealant. Let it set up for a few hours before you start the engine so back-pressure doesn't blow it out. I hate to say I did that over 15 years ago as a "temporary" fix on my '88 Grand Caravan daily driver. It isn't leaking yet, over 150,000 miles later. I used Chrysler's gray sealer because it gets harder than their black stuff, but every dealer and every auto parts store has the same stuff with their own name on it.

I would never recommend stop leak for anything it usually doesnt work and causes more problems than it solves. Also where is it leaking?Did you knock a hole in the pan?
Was this
