For example, on a D16Z6, most civilization I have actually encountered include a final step the 65 lb-ft.After about 10 warm cycles of the engine remove the valve cover and check the torque come make certain they"re still in ~ the final torque spec. Tighten earlier to specs if necessary.The studs themselves need to only be hand tightened into the block; the nuts space what you use the talk wrench on. Also, the is less complicated to lock 2 nuts with each other on the stud and also use a socket wrench top top the optimal nut come tighten the studs, as opposed to using an allen wrench in the allen socket in ~ the peak of the stud.
