I just threw that out there. I have no idea. Did you buy your truck new?
i was actually thinking a seeping valve cover gasket. but the whole outside plug that wasn't in the boot should have oil on it.


The oil could have been from the last install. It is always a good idea to lube the threads of those plugs prior to installing them. That way they don't seize up, then you have a larger problem on your hands.
Thats why I brushed some anti-seize lube on the threads of each plug before I installed them.Perfect Scott, you have nothing to worry about.

The dealer who sold it to me even gave me a printout of the initial vehicle inspection when it was traded in, along what was repaired. It was all minor stuff they did; replaced the tires, wiper blades, a power window switch, and inspected and cleaned the brakes (but didn't replace anything on the brakes).The oil could have been from the last install.

I agree with Red,those plugs simply show signs of alot of miles.I'd say they're burning well.The oil might be from some reisdual oil in the spark plug recess and dripping on the threads as you unscrew it.Does the valve cover show any signs of an oil leak near that plug?
I even thought maybe it was a bit of oil that was spilled during an oil change, but the fill spout is on the passenger side.
