As it turns out the leak wasn't coming from the oil pan on my 1995 3.4L, but there were two other leaks. The worse of the two was coming from the oil filter adaptor gasket mounting bolt. The other (that was just starting) was the front crank seal. It took about 7-8 hours to do (including two trips to the parts store), but I'm glad that I did. I found out that the timing chain had about a 1/2 inch worth of deflection. Just wanted to let you know.
