alright then, what should I do then, 3/4 of a turn? I'll do what you recommend and start her and let he run. by the way, I keep having problems with the t-stat housing leaking. doesn't seem to be anything other than the gasket. should I make my own, and if so, what would you recommend for thickness/type? thanks again guys, and I'm glad I didn't ruffle your feathers Rusty, by the way.....who said I was in my right mind?
