Yesterday i put a new valve cover gasket in so after my drive home from school i popped the hood just to check on it. My engine was extremely hot (only a 3 mile drive). I decided to pull my plugs to check them first. They were very white, little bit of black on the top of the threads, but the electrodes where a very dry white. Now i know that my Fuel Check valve is compromised, i have been starting it for the past year by priming the pump a few times before cranking it. Could this have anything to do with the engine running lean? Not enough fuel to the injectors? Or could it be that the injectors aren't spraying enough fuel? I check my air filter and it looks fine also. Here are a few photos of plugs from different cylinders. All look the same.
