everyone I got a bottle of blue devil from a part store that I do business with last week when I went to buy a head gasket for a truck they gave me the bottle which is normally 60 bucks a bottle told me to try that and see if it helps. I did as directions told me too while here at the shop and what do you know it truly sealed a head gasket that was visually leaking idle returned to normal check engine light went out and no overheating or anything. That stuff worked for me my mechanic was skeptical and still insists he needs to replace head gasket but I said lets see how long this holds. It was idling rough and puffing alot of white smoke after 20 minutes it stopped smoking and idle returned to normal. I mean even if i paid 60 bucks and it lasts a few months it was worth it. It says you can use in diesels as well.
