They are known for having camshaft bearings get too much clearance, and then the lifters clack and eventually it dies. Band-aid is the correct description for putting in a hi-vo oil pump or heavier viscosity lube. Covers the wound, but does not heal it.

There is no quick fix except turning the truck upside down and shaking the engine out. Turn it shiny side up, and pop in a new one! Easy as pie. I wish.
