What those it mean when there’s oil inside the coil
Usually most of the leaks on the outside of the block or inside the cylinder combustion chambers are the result of a faulty valve cover gasket. When this happens, all you need to do is just replace the valve cover gasket. Installation of a new component is rather a straight forward process. To get the job done, follow the process: Remove the valve cover from the head of the engineRemove the old gasketKeep the area clean with a ragSpray some silicone spray where the gasket will be placedPlace on new gasketPut the valve cover back, and torque valve cover bolts back to spec.
