Blowen head gasket sealer anyone? (FYE)
FYE (For Your Entertainment)
Recently we had a 1995 Land Rover Discovery that belonged to the owners son for his car lot with what appeared to have all the signs of a blown head gasket. Me and the shops owner decided to do a little experiment, we were going to see if the claims of a popular brand of "cracked block/ blown head gasket sealer" were true. Since the head was going to come off either way, who cared if it works or not, we felt like being mythbusters.
Following the instructions to the letter, about the halfway through the hilarity sets in, according to the instructions we were to run the vehicle with out the spark plug in for 5 minuets! HA!!!! Sounded like a old propeller airplane was running behind the shop. A few people looked in the back to see what the heck was going on. Well, to make a long story short: It didn't work at all. It turned out that the whole motor was shot, the second cyl back on the drivers side was leaking where the aluminum block and steel piston sleeve met on the deck. In theory this stuff should have "fixed" it but no dice.
