Well....here's my $.02. I have a 351w block, and I had
oil coming around the head stud nuts from where I coated them with
oil to torque them. That's the only thing it could be, because on a 351w block, the head studs aren't in any water passages....So I was thinking maybe you're just weeping a little
oil from where the nuts were torqued....how much is it actually leaking?
