I bought a 90 talon turbo awd yesterday for $700. Its a victim of someones ex vandalizing it. Body is good other than broken tail lights and such. The tank door was pryed open and sugar was put in the tank. My guess is he didnt notice pry marks and drove it. I pulled valve cover and "all" of the intake (firewall side) roller rockers are broken and or came off lifters. The exhuast side isnt damaged. I retrieved all pieces except a couple. My question is what the hell happened? I assume the sugar gummed up valves on intake side which didnt allow them to close and some thing had to give so the rockers exploded? Or the pistons hit intake valves? I need to know what needs to be replaced, just head and flush fuel tank, or does the bottom end need fixing also? Any advice would be helpfull. Has any one experienced this before?
