So I found antifreeze in one of my cylinders (by-product of overheating the engine)... 1. Any suggestions? (hints, where to buy a gasket kit, etc.)? 2. Anything else I should replace "while I'm in there?" It's an ATX with 16x,000 on the odometer. 3. And most importantly, is there an easy way for me to tell if I screwed up the engine (warped the heads, etc)? TIA. John. 94 ATX rare green
