I noticed that I had a couple small oil leaks near the Valve cover screws. when i tried to tighten them, they were really loose. I snugged them up (all were loose), but just how tight should they be. This car lives/lived on a rough dirt road and I wonder if they loosened, or never were tight. I'll watch this to see if I stopped the leaks.
Any ideas?
