I am waiting on a leak down tester but looked at the PCV valve (no excessive oil in the hose), a few spark plugs (all were similar with one light and one dark side of the center porceline, no evidence of oil), and attempted to look at the valve stem seals (valve springs prevent viewing them). I did confirm that there was no obvious oil smoke on start-up after sitting for several days compared to significant oil smoke at idle after driving.
Once I have the leak down test information I may be better informed but I am leaning heavily toward running it for the rest of the summer to see if anything changes and if not plan to tear it down over the winter months. Other than the anoyance factor of being a smoky truck when driving into car shows and needing to add oil more often than desired there doesn't appear to be any significant risk of additional damage to anything.
