Oil leak

[~4N~]

I went to Walmart to get an oil change a few days ago. The next day I found a huge puddle of oil under my car, so I took my 240 back to Walmart. They mumbled something about spilling oil or something, and that they cleaned it, and how it should be fine. Well, yesterday wasn't too bad, there was some oil, not too much, so I thought maybe it's still some leftover oil, but today there was another huge puddle under my car, and it's only been sitting in that spot for a little while. I'm going back to Walmart today, I'll see how things will turn out.My 240 has never leaked a single drop before.

Right now, they're putting some kind of a thick oil in it, which might not leak. I guess the previous owner used thick oil, which helped seal the leaks, but he didn't tell me when I got the car. I used normal oil the past 3 or 4 times, and I guess it ate through again. Hopefully the thick oil will help, but I don't know yet.Is there any way to somehow seal an oil leak (glue, etc.) without having to pull out the engine and paying $1500?Any input is appreciated, thanks.

Your first task is to find out where the oil leak is coming from.

See if it's from the oil draing plug (they may have stripped it - uh oh), or from the oil filter, or somewhere else around the engine.

Once you know where it leaks, then you can figure out how to fix it.

It drips from two spots, but it's neither from the plug nor the filter. I checked both and they were dry. I know where they're located, but I can't really tell you what they are, I'm pretty new to cars. Is there any kind of a sealant I could use if it keeps leaking?

sure, you can use some sealant - like rtv silicone, thermo gasket sealant, etc.

but where is the leak coming from? you need to be more descriptive.

If you want to do it right, you may want to remove the entire part (for example, leaking from the oil pan), and cleaning it up & resealing the whole thing.
