no. The JB fix helped me alot, but its only about 90%. The cold weather I think didnt help the cure, so it seeps a little.
I let the ones you pointed out on ebay go. Decent price, but i didnt like the guys shipping charge, and the trucks running good enough to be patient. I could drive it evryday with no prob right now, but that truck sits mostly as i drive a service truck during the week. -- another reason for no hurry.
And I doubt the crack is a result of bad cast, the boss is just split like I over tightend the plug. I thought I was carefull, but apparently not.
The same guy with the ebay filter canisters had several other CTD parts as well. I almost bid on a harmonic balancer but It was ending and I couldnt get the bid in fast enough.
