Just replaced my valve cover gaskets on my 1984 Corvette the question is are the valve covers supposed to be torqued down or just snug if they are to be torqued does anyone know what the number is in inch or foot pounds Hope to hear from someone soon

 

I personally use the "Calibrated wrist" method. The bolts are 1/4-20 hex head bolts and the Torque spec
for them are 76 in lbs

 

The FSM for my 1985 says to torque them to 50 INCH pounds, which is super light. I'm sure there were a bunch of reasons for that back then (only using RTV) but the new gaskets I just put in did not like it. I just snugged them up real good and the leak has seemed to stop for now.

 

there was a TSB that did away with the use of RTV sealing the valve covers, and replacing it with gaskets. nowhere does it address the torque spec, so i'm assuming it remained at 50 inch pounds. I replaced my gaskets with blue silicone fel-pro's some 5 years ago, and torqued them to 50 in.lbs. and to date, they haven't leaked - still bone dry. in a nutshell, i replace the OE studs with moroso #97020, and use fel-pro 1628 gaskets.
