Araber, if you can get your hand behind the intake or heads, feel around for oil up there. Maybe it's just dripping all the way down to you bell housing. But if you tear it apart again, I would change the rear main, not that hard and it won't leak.
If it wasn't raining today I would love to go to Thompson. But hopefully we get a nice day before the end of the season. Curious of what my car will do now. It feels like it has a ton more torque now.
