hey guys i have a 02 trailblazer 4.2L and my check engine light is on with a p0301 code so i look at #1 cylinder and i notice its full of oil. I know i need to replace the coil and plugs. And i also know the valve cover is leaking and i am just wondering if anyone has done a cover gasket job? how long it took them?
Ps. i am pretty mechanicly inclined.

thanks PJ

how much oil is exactly in there? when you pulled out the coil, was it drenched?
