torque value for valvecover studs and warped covers ?

Hi
I removed my valve covers for the first time. God they where warped!!
Anyway, when I removed them 4 out of 6 studs came off (top covers). How much should I torque them up when replacing them and should I use som type of loctite?

If I remember correctly these only need to be at about 8-10lbs. No loctite but use lock nuts (the kind with the the nylon insert).

Just re-read you question. I think I misunderstood. For the studs you probably could use loctite and torque them to around 16lbs.

Yes, the nuts are 11Nm. Figured I could torque the studs to maybe the double, but its always nice to hear someone else say it to. I thing Im going with loctite if no one here has a different point of view...
Thanks!

One of mine came out of the lower side... what tool do I use to reinsert? The Snap -On tool on page 36 picture #2-37 of the engine book or can I just put a nut on there and screw it back in?

Or should I not reuse it at all?

Due to my warped upper valve covers I'm going to have them machined. How much can you take away before it gets to thin or the rockers hits? 1-2 mm should be ok, right?

The studs are not torqued. You just screw them in until the right amount is exposed. Use some Loctite to hold them in. If reusing the stud (I usually do) run a die over the rusty threads to clean them up so the nut doesn't try to unscrew the stud the next time you remove the valve covers.

Not torqued and loctite, noted! Thanks!

Not correct. The factory torque spec (in the spec books) is 8 Nm (6 ft-lbs).

safe: Yes, the die I'm refering to is a tool that cuts threads on the outside of the shaft. If the stud came out with the nut, chances are it is so rusty that the nut didn't want to come off. To prevent the the stud from unscrewing with the new nut you can either use a new stud or clean the rust off the threads by running a die over them to recut the threads on the old stud.

Wayne: All I can find in my ('84-'87) spec book is the spec for "Cover to camshaft housing.. 8 Nm" which in my mind refers to the torque for the valve cover nuts (not the studs).
