IM STUMPED! Heres the story,
My water pump went out so i tried to get it home one day and over heated bad. Next thing i know i have white smoke coming from the tail pipe so as a precaution decided to change out the head gasket and all others at the time i was doing the water pump change. Well i brought the head to rep machine shop and had him magnaflux it and do any other work that needed to be done. He said it was good to go no leaks and he leveled it off. Well get it home put it all back together... start it up and..... rough idle white smoke, ran like crap. I said ok maybe just didnt get the head on right or i messed something up along the way. SO got another head gasket replaced it again torqued every thing to spec and sequence, changed the plugs and the wires, and bam ran great. I ran it around town for a little while everything running better than before. So I got home from work tonight and cranked it up. almost immediately getting white smoke again, but this time motor sounds like its running like a champ (No ruff idle).
THE ONLY THING I CAN THINK OF is that i used the original head bolts...
PLEASE SOMEONE HELP
