I checked up under the car and I see what looks like oil on the curvy downpipe that runs before the flex section. However I poked it with something and I didn't see any come off onto the stick. And now that I think about it, if it was oil on there, it should have burned off when the fire was going, or at least when it got hot the 2nd time I started it up. I'm just speculating right now, but hopefully my friend can't get back with me. He's a mechanic on the side and actually has a garage and lift and tools at his house.
