Got my truck back on the road last summer after it sat for a couple years. While it runs well and I forgot how solid the truck is, the valves tap rather loudly.

Wondering how easy it is to adjust the valves- OR if some oil additive (Sea Foam?) would work at all?

I haven't used it myself, but I hear a half quart of Lucas heavy duty oil stabilizer will cure that. See this thread Can you run 0w20 oil in your late model 4.7? | Dakota Durango Forum (dakota-durango.com)
