When i get my motor to running temp(160). And drive down the highway and left off without using the brake i get alot of white smoke out the back after about 20sec of slowing down. but only when the motor slows the truck down. I can sit still and rev it up with no smoke but when i let off its all there clear as day. I running moble 1 on a motor with unknown miles. my only thought is moble 1 wasnt used from the rebuild and when i go to put it in it burns it cause its synthetic. IM Lost???? Blow By???

White smoke is usually water, are you sure it isn't gray/blue.
Possibly bad valve guides & valve seals.

Sounds like oil coming up past the rings to me. I would try Castrol 20W50 and see if it helps. All you've got to lose is 20 bucks and some smoke. :2cents:
