I bought my 80 about a year ago, at that time I started doing several PM items (valve cover, wires, plugs, rotor, pcv, air intake hose). I then got distracted by lifts, tires, bumper, winch, more tires, etc. you get the point. I'm back on the the PM track and plan to replace all three belts, flush radiator, replace three radiator hoses, thermostat, PHH, idler pulley. dizzy o ring, HD tie rod/draglink. Water pump is fairly new, power steering pump is new, oil pump gasket has been replaced, anything else I should tackle while I am in there?
