Slight oil seepage may occur if the valve cover nuts are not sufficiently tight. This can be primarily caused by compression of the valve cover gasket.
Therefore, retorquing of the valve cover nuts may be necessary.
Check valve cover nuts for proper tightness at every service interval, and correct as necessary.
Correct torque is:
12.5 N-m = 9 ft.lb.
Oil seepage is not an indicator of a defective valve cover gasket; therefore, gasket replacement is unnecessary.
