snug?
i would appreciate anyone could tell the tightening torque required for the studs on the cylinder head,which hold the valve cover cap nuts.

about as tight as you can get it with just your wrist and a 1/4 drive ratchet, the nuts bottom out on the studs, what really applys pressure to the gasket is the little rubber doughnuts under the washers, i allways replace those when i do a valve cover gasket
all america wants is cold beer warm cat and a place to take a poop with a door on it
the reason i was asking is that on the bentley it mentions 10nm for the nuts, but the stud couldnt find its torque needed at all.last time i changed the valve cover gasket i found at lesat 3 studs gone bad,when i tried to replace the stud i found it really really tight on the cylinder head, i fear applying too much force on them and damage their place on the cylinder head creating worse problem.Originally Posted by winfred
actual torque on the 6mm studs is 10nm and on the 7mm studs 15nm.. The nut torque is the same as the stud torque.. Just out of curiosity , what do you mean 3 studs gone bad?

but Bill,if the nut is 10nm,in theory the stud should be at higher torque,to avoid them coming out together,when untightening the nut cap?right?

stud to keep it from backing out, but you only use the blue loctite so you can remove them if you need to.
