I have the right socket and some blue loctite on the way. What's the recommended torque on the valve cover bolts? Do you recommend unscrewing them completely, or just enough to get some loctite under the head?

Loctite goes on threads not the head

Rockauto has decent prices on these.
Pull the outer screws, put the loctite on the threads, tighten until snug. If it does not stop leaking, then you can do the gaskets. I've got a fiver that if you do the FV308 and tighten the screws the leaks will go by by.

Valve cover leaks
_________________________________________
Loctite is good; I use it a lot. However, for some applications, old fashioned split lockwashers are good too, and usually much easier to get on/off. Using allen head bolts, with old fashioned split lock washers; same threads and length as original valve cover bolts worked wonderfully for me, in making my original valve cover gaskets seal agai. The thing is still not leaking, after my adding the allen head bolts and lock washers, so explain to me again why loctite is better, when leaking has long ago stopped? Loctite, I am sure, would have worked too, but probably would be harder to get bolts out later. Loctite doesn't work well at all, when oils are on the surfaces too, while the lock washers will.

Just sharing my experience fwiw....
Yep ”blue” Loctite has never failed me & you only need like maybe 5mm of the threads to be coated. Blue Loctite coated hardware is easy to remove. It’s the Red & Green Loctite that will be a PITA later on to remove.

I know they have different sizes for the bolts. What sizes go where for the 12 point bolts for the passenger side?
