BLUE DEVIL POUR AND GO HEAD GASKET SEALANT

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

My car was losing coolant through steam probably head gasket issue. Believe it or not I've used more than 250 litres of coolant and distilled water in my car in the space of 4 months. I had to risk and use this blue devil pour & go gasket sealer after reading reviews online and watching youtube videos. I followed the steps in the bottle except removing my thermostat which was a risk. Its been a week and no more coolant loss, no more gurgling noises in the system, No overheating, steam has drastically reduced, at times no steam at all. Car was like a chimney before even after driving for hours steam was still emitting. I must admit for now the product from bluedevil seems to work very well.

Didn't work at all

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.

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.

Worked a treat would highly recommend

I've held off writing a review of this product in the 3 months or so since I bought it, as I wanted to see how well my car was doing. I was told my head gasket needed repairing on my Mercedes and I was looking at nearly £1000 in costs. I was all set to write the car off before hearing about Blue Devil. For around £30, I thought "What have I got to lose?" I followed the instructions and was soon driving my car again as normal, with no overheating or engine problems whatsoever. However, being a cautious sort of chap, I thought the real proof of the pudding would come at the next MOT. Well, that was carried out today and the car passed with flying colours, with no advisories whatsoever. Can't tell you how overjoyed I am, and really can't recommend this product enough.

did the job
