alright, i changed my spark plugs tonight (finally! lol) and once i unplugged the 1st and 2nd wires i noticed oil around the boots. the rest of the plug boots were dry. there was oil in the galley or whatever you wanna call it ( the area between the cams). is this the valve cover gaskets leaking? i'm still learning about the 7M's so any feedback will be greatly appreciated. thanks, Josh
