Depending on the truck, its a simple valve cover issue, or a splash shield in the oil pan. Not too many piston slap issues anymore. A well take care engine will outlast everything else on the truck. And I doubt the rear main was leaking, very rare that they do, most likely the oil pan/oil cooler to pan gskt. Hubs and water pumps are big problems after 100k. Besides that, tough trucks, and even tougher motors. Oh and the cluster, they fixed that by gettin rid of the pesky thing lol

Thanks for the info. I was told this one shouldn't have the piston slap issue but we'll see.
