Hello, I have a great problem that I am a bit desperate to fix. I have a 1999 Buick Lesabre with 110000 mile on the v6 3800 series engine. The other day the head gasket blew out with all the classic symptoms. I paid $2000 for the car so I wasn't willing to take it to a mechanic and possibly pay $2000 for a head gasket job and I don't have the time to do it myself. I thought I might try Barr's Leaks but this is where the problem started. When I added water to the radiator there was plenty of water vapor coming out of the exhaust so this verified the gasket on at least one side of the engine was blown. I happened to tap the gas pedal one time when I was getting out of the car and the engine stalled and there was a loud whistle sound. Now the car won't crank. I only get a click when I turn the key. I can't imagine what was shorted to cause the engine to not turn over. Any Ideas? And will it even matter if the Barr's Leaks clogs everything up in the end anyway?
