FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! FAP! sound under the hood. After I put in the solid copper gasket I got in and started it up. Sounded good, but something now right... idled rough... then I remembered I had disconnected all 4 spark plugs on the side of the motor where I was replacing the gasket. It still started right up and ran on 4 cylinders! WOOT WOOT!!! I plugged the wires back up and restarted the motor... Ran better, but was backfiring... Yeah, I mixed up a couple of wires. Put them back in the right position and it purrs like a kitten now. Like a kitten with about 170 horses shoved up it's @ss. :-D
