Got another project car with a bad motor-knocks like crazy and put some water in it and it turned to instant milkshake. Can't wait to do the autopsy. Anyhow, I bought a new intake set because the car's owner "thought" the guy he hired to fix it at one time before it sat for a while had swapped the motor out. WRONG. So after looking at my gasket set I bought for it and subsequently installed, and took apart after pulling the motor out, they appear to be re-useable. Besides I only used them to run the motor for about 10 minutes. Anyone have the skinny on this?
