Studs or stock main bolts? if studs, #5"s are hitting the back of the pan. Not the main seal at all. Been there done that. Other than that . don't know what to tell ya.
Sorry, yes studs. Definitely not the pan. Ran the engine and observed leaks without slinging it everywhere. Leak is plain as day running down from the seal journal ABOVE the pan. Thanks though. J.Rob
