1) Since i'm taking off the valve cover and doing valve cover gasket and grommet change. What is the torque specs when i screw on the bolts again to tightened the valve cover? Is there even any can i just tighten it until its tight?
2) and also do i need to put RTV silicone on the grommet area and around valve cover? If yes, where specifically?
3) This is the spark plug that was covered in oil.
