I have a 2002 S-10 Blazer. I noticed some oil on the floor. It appears to be coming from the front of the oil pan, above somewhere. There is no oil around any bolts holding the pan. Is it something as simple as replacing the gasket. Or is there something that runs into the front of the pan somewhere that will be nothing but grief. If so what kind of cost am I looking at? Thanks in advance.

 

Possibly the lower intake manifold gasket is leaking behind the AC compressor and running down. Need to get a light and a small mirror on a stick and check it out.

 

Are you sure all the oil pan bolts are tight? This year is known to have a problem with the front two pan bolts not staying tight and falling out.

 

Another common source of leaks are the remote oil filter and cooler lines, take a look there.
