I need to replace a valve cover gasket as it is showing signs of leaking on the sides near the front of the cover. When doing this, should the timing belt be changed as well since various parts are removed anyway. What else should I look for and replace at this maintenance time as well.
thanks for your feedback.

 

Unless you have a diesel there is no timing belt.
And save yourself some time and money, but a 8mm 12 point socket and tighten the valve cover bolts at every oil change, they work loose and leak, tighten them back up and leak is gone.
