has anyone heard of blue devil headgasket sealer? i was thinking of putting some of that in for now till i get the head gasket fixed. i took it in to a shop for a blown head gasket check and he said it was an outside head gasket issue and told me to put the blue devil head gasket sealer in till i can afford to get it fixed. for 60 bucks it better work. water has not gone into the oil just blows out of the exhaust sitting at the traffic light. i need to make a trip to ca and back (wa) he said it will be fine once i add it. any thoughts?
Haven't heard of blue devil, but I assume it's comparable to BarrsLeak or Stop leak. Putting those types of additives into your system will cause addtional damage to the water pump, heater core, radiator, ..etc. If it's not overheating, I would drive it until you can fix it properly. I drove my 92 with a blown head gasket for over 2 years.
i do want to put some type of sealer in it before i go and im going with the blue devil cause it has no metal shavings in it. i did use the bars leak for cracked heads and blown head gasket and it seems not to work.
Blue Devil worked great for a toyota 22re that was so leaky it would hydrolock and the oil was all milky looking. I have a thousand miles on it and no issues so far.
As I understand it the stuff crystallizes as it is exposed to the gasses in the combustion chamber. It won't crystallize in the cooling system as long as it lacks the gasses that catalyze the reaction.
It has a money back guarantee and I used it on a truck that was destined to be a parts truck so I had nothing to lose.
