BLUE DEVIL POUR AND GO HEAD GASKET SEALANT

Worked a treat would highly recommend

Definitely patched my head gasket problem. Follow the instructions to a T and it seems to have improved the state of the engine. Initially, I was still having rough starts (probably due to the remaining coolant within the pistons) but overtime this has improved. Only time will tell how long this lasts. 5 Stars.*Note*If your car's coolant is leaking into the oil (milkshake looking oil) do not use this product as this can cause clogging within your engine which could lead to an engine replacement completely nullifuing this as a cheap solution to an expensive problem. This product works by using the high engine temperature, changing the state of this solution to a soild, to seal the head gasket. The oil is exposed to these tempertures leading to a clogged system. Please check before using. I'm far from an expert so do your own research to ensure this product is right for you. Good Luck

Didn't work at all

Very good, excellent

i bought this one because it had the most "good" reviews and since i have used it I haven't had any more problems so it seems to have done the job.

My beloved Mitsubishi Galant Sport which I have owned for 8 years developed a leak in the head gasket and it was looking like curtains for it as the repair cost would have probably exceeded its value. It was using about a pint and a half of water a day, running on 3 cylinders at start up and bubbling air back up through the cooling system. Luckily I found out about head gasket sealants and it seemed Blue Devil looked like the most reliable. I simply followed the instructions (white label) - slowly poured it into the cold radiator with the engine idling, heater on max and left it for 50 minutes. It did its job brilliantly straight away. This was less than a week ago but it has been running sweetly since, has not used any water whatsoever, not misfired once and I have no bubbling back- pressure through the expansion tank, and the engine management light has gone off. The only thing I did differently to the instructions was that I had already taken the thermostat out a couple of weeks before, just to keep the temperature down. Obviously I cannot say how long this will last but I can say that this product is bloomin' BRILLIANT.What annoys me is that my local garage that I have used for most everything for several years didn't bother to tell me about the existence of head gasket sealants - and they must know about the stuff - even though they knew that I would not have the gasket replaced as it was uneconomic and was totally depressed about the situation. Maybe they will have a couple less customers from now on.

did the job

Works as it should, probably. I don't remember much after testing to see how blue it tasted. I advise not tasting it, it wasn't very good at all.
