Greybeard,
I know this isn't directly related to your oil leak problem, but Bruce Sackron, Carl Swanson, and myself are all going to be at Firebird this weekend for the Oldies drags on Sunday, June 8th. Bruce is running a '63 Nova with a 250 in it, so maybe between the 3 of us we can figure out something to fix your 250. And if nothing else, taking a break sometimes helps to figure out a solution to a problem. We're also trying to put an Idaho chapter of Inliners together, so we'd like to meet anyone who is a six cylinder fan. You can call me at (208) 362-7655 if you'd like to.
