If it's cold outside it could be just normal water condensation. Are you still losing coolant? Does the exhaust smell sweet? Is it large billowing clouds of water vapor? If so then you still have a problem. HTH. -Jim


Yes on all three could it just be the head gasket

Yes, it definitely sounds like it. Head bolt torque is very critical and on some applications the head bolts cannot be reused! HTH. -Jim


I had new head bolts put in when they bleed it Brown stuff came out

Sounds like whomever did the head gaskets didn't do them correctly. I'd recommend you take the car back to them and have them do it over. At THEIR expense! Also sounds like somebody put some stop leak junk in the cooling system to try to "fix" the head gaskets without spending a lot of money. A good cooling system flush needs to be done to get the stop leak junk out of there. That stop leak junk causes more harm than good!! HTH. -Jim


Torque yield head bolts have to be torqued correctly and in the sequence pattern 3 or 4 times Torqued to 25 LBS in sequence then back to # 1 head bolt back it off and then torqued to the next bolt in sequence back it off and re- torque as the step before continue this until all head bolts are torqued then do this procedure again torqueing the bolts again Then put the torque wrench down and get a breaker bar and give each bolt a 90 degree turn in sequence repeat with another 90 degree turn Or go to victor gasket and see if the procedure is the same

Ok I'm having someone else look at it Tuesday I don't think the one that did it knows what he was doing I've been waiting a week for him finally gets it done and still doesn't run rite

I also agree on the flushing the radiator I don't think he did that rite either


when backing off the head bolt do them one at a time torqueing it back down before proceeding to the next bolt
