loose valve? as in the truck needs a valve adjustment? why not just do the valve adjustment, they aren't hard to do, but you do need the proper shims, which if you don't have a collection can be a bit of a pain.
as far as the rattle on acceleration only, that sounds more like detonation than a problem w/ a valve, but w/out hearing it, its a hard call to make.
The seafoam is an engine cleaner, i don't know if they have an oil additive or just a combustion chamber cleaner, i've never used it myself.
