This truck was neglected and driven with severe oil leaks for so long that the rubber in the harmonic balancer softened, allowing the pulley to slide back & cut through the timing cover, causing even more leakage. It wasn't repaired until it was so bad that the owner was replacing a quart of oil a day, and the belt every week. The valve cover gasket, side cover gasket, both engine mounts, trans mount, & belt had to be replaced.

A week later, he returned for a leaking radiator hose, also damaged by oil saturation.
After all these repairs, he now uses the truck to haul more weight than he should across a few states, but the truck is reliable again.
