I'm Awesome
my vote is pull it and do a very good inspection,, the star wheels get hairline cracks in them, the magnets lose thier magnetism, the shim above the drive gear wears, the gear wears, the shaft gets gunked up inside the housing, the electrical module gets brittle, the insulation falls of the wires, ect.. you really dont realize how crappy a truck is running until u put a new distributor on. the distributors on these trucks are so important for the truck to run right. the duralast gold replacement ones are very good with lifetime warranty. 140.00 they come with everything, including a brass terminal distributor cap and a rotor that actually fits properly, no slop. when the shim and gear wears in the distributor, it creates slop,. it then pushes the rotor up against the top of the cap, wearing out the caps. slop will also cause misfires and carbon tracking on your sparkplugs. if u see a black line on your plugs coming down from the electrode, the plugs are partial misfiring. after I replaced my distributor, I put an empty aluminum can on top of the air cleaner and started it. I let it warm up good, and watched the can. the can barely moves at all. just a tiny vibration. I showed my neighbor and he was impressed at how well it ran with over 200.000 miles on the original engine. never been in the engine.
