The stock valve cover bolts on the 3S-GTE engine have a Phillips head and are very difficult to tighten to the proper torque specifications. As a result, these bolts tend to vibrate loose and cause your valve cover to leak. Several owners have found these bolts to be finger tight at best when inspecting. In order to solve this problem, replace your valve cover bolts with our hex-head bolts.
