I dont know whats up? I have Burnt fuel in odd places. My truck isnt over heating, but my exhaust gasket is ripped again. It seems like ever time I put a gasket on it becomes ripped right away. there is also burnt gas on the top of the header, just a little, not as much as last time, the top of the head button is a bit wet with gas, the Cooling fins are a little wet on the back side. There is also notch in the first gold ring in the piston sleeve cause the second one is a little wet w/ gunk on it and the one on the head button is also a bit wet. It puzzles me because the truck isnt overheating, but im affraid if i put the gasket back on it will continue leaking and start to overheat. The truck isnt smoking, the piston is completly silver, the head button isnt burnt. How can i put on a gasket or can someone show me a pic of theres.

The notch is on the right side of the engine on the rear side, right next to the screw hole.
