So far, so good. Blue Devil seems to be working, as I see no leaking from under the head or intake manifold. Haven't put many miles since treatment, so a little more time driving will tell. I did not remove the thermostat and replace with a new one, as instructed, but seems to have worked anyway.and engine runs cool. Blue Devil is definitely worth a try, especially for the cheaper price through EBAY.

Product cause more problems with the car heating system now not working. No information on bottle stating heating should be left on full in order not to block heating pipe. Did not block hole in head gasket but opened the hole wider not oil is pouring into water system

My nephew's 95 Honda Civic. Blew between cylinder into the water jacket,so white smoke , leads to less water then overheats. Blew out white smoke but not alot. First of don't rush into pouring blue devil in. I've been wrenching over 30 years. Before you do it ; 1) Do a real radiator flush. I used Prestones Super flush. Cleans metal surface of head to block for better bonding. TRUST ME IT'LL WORK !!!! 2) Completely flush system out with water to rinse out Prestones Super Flush and just please follow the EXACT Directions. 3) With radiator empty ( and engine cold ), pour ( Blue Devil ) in the right amount needed for your vehicle , top off with water and top off overflow tank, start car and turn heater on HOT fan on high for the EXACT time no more no less...... My nephew is a happy camper. Now that being said he cruises all over on the Big Island and up that steep drive to Maunakea ( Big Island Hawai'i ) no problems. Car never over heats , idle is smooth , little more umph in the motor, and everything is working like it never happened. Believe what you want, flushing out your system makes perfect sense doesn't it ???? Same thing like painting a car, you sand it down and clean it paint sticks better. Like welding clean surfaces well the weld fuses much stronger. So too is the molecular bonding. FLUSH WITH PRESTONE SUPER FLUSH FIRST. THEN USE BLUE DEVIL. YOU WON'T BE SORRY...GOOD LUCK TO ALL GOD BLESS FROM DA HAWAIIAN ISLANDS ...BRADDAH "D" Read full review
