still isnt fixed, cooling problem part 3

[fiveohpatrol]

the damn thing still isnt fixed, i put the pep boys heavy duty 3 row radiator in there today, went for a drive and it was fine for about 15 minutes, then started to heat up, and i noticed white smoke out the tailpipes when decelerating and at idle, came home and checked the oil praying that it was fine, nope, the oil was a milky light brown, but there were no bubbles in the overflow tank or the radiator when running, i talked to a friend that knows his **** and he said its probably not the head gasket because theres no bubbles but most likely the lower intake gasket has either moved or because i hadnt put black permatex around the coolant openings in the head it is leaking into the lifter valley and thats how its getting in the oil, i'm gonna be taking the intake off 2 weekends from now to redo it and he will be helping me NOT screw it up this time, any one ever had a problem like this?
