Very cool, there's nothing like finding a cheap fix to an expensive appearing problem.
That happened to me Friday with my Toyota Solara which looked like it had a major oil leak from the main seal. The engine and undercarriage was covered with oil that it was hard to tell where the oil was coming from. I had been driving it for over a month and adding oil regularly fearing the worst. Turns out the gasket on the oil filter had simply blown out. 30 minutes at the local coin-op carwash to clean things up and a new filter and oil and things were fine again. Phew!
