front main seals on our cars suck ass! it seems like everyone w/a ga16de powered car has their's go bad at some point. ya'll should see my engine. i never cleaned the block of anything else the oil got on bc i didnt think it was that bad. but when i changed my belts and took a good look around the engine, it was horrible. btw, gunk engine brite works great at cleaning your engine bay and block. works even better if you have an old toothbrush.
