It's not blowing oil (from the oil pan anyway). It's just an untouched 93K short block. It's never been unbolted from the frame. Now, leaking oil all over the damn place from the 4 valve cover breathers, that's a different story. I know how to handle the rubber gaskets (and even cork), but I still hate them lol! Can't help it.
I'll be doing exactly as you said if I can't find a 3800 style gasket that will work with no problems. I called Magnum Gaskets tech support because the link I posted says it's for NA 3.8Ls, no turbos. The tech could not tell me why, but it supposedly checking with the engineering department and will email me an answer at some point.
