    is the 4 cyl engines on an 86 pre taco not interferance engine where if the timing chain breaks it wont damage the engine? i found a 86 yota truck with a broken timing chain for 800 that i can try to talk down and replace the chain on the spot with my uncle then test drive it if it doesnt cause engine damage :)

    The 1984-87 2.4L Pickup is an interference engine according to this site
    http://www.aa1car.com/library/timing_belts_interference_engines.htm

    A timing belt failure is bad news because when the belt breaks, the camshaft stops turning and the engine dies. Worse yet, if the "interference" engine (one that lacks sufficient clearance between the valves and pistons if the cam stops turning), the result can be one or more bent (usually intake valves), and possibly a broken piston. This kind of damage can cost several thousand dollars to repair!
