I pulled the valve cover off and it’s clear the truck has been sitting and neglected for longer than I thought. I expect I’ll have to tear everything apart and see if I can get it going again. I don’t think the truck is ready for the recommended engine revival procedure based on how this area looks.

I see this book recommended, opinions on this or other resources I can use?
