Re: I need a valve adjustment... (ericshaw)
uh -- there is no "torque" setting.
Assuming you have a hydraulic cam:
You can adjust them while the car is running at idle. Get the clips or plugs for the rocker arms to keep oil somewhat (yeah, right!! ) under control.
Once running, back the nut off until it starts to rattle a bit, then tighten about 3/4 of a turn. You will be able to hear when they start to rattle. You want to take up the slack and get rid of the rattle and then give it another 3/4 turn. Do that for each rocker and you will be set.
For solid cams: contact the cam manufacture for the settings on how much gap should be between the rocker arm and the valve, and how to set them to their specs.
Good luck and enjoy the oil bath and smoke show !

I use 1/2 turn after the knocking stops myself but its all a matter of choice. You'll see answers from 1/4 to a full turn.
You should read Lars article on "How to adjust Valve Lash." Go to http://www.corvettefaq.com and go to the engine section. You will find it in there. He has an easy way to do it without running the engine. I like to do it with the engine running. Its faster but a lot messier.
This is definately a do it yourself job!

Perfect anti - messy valve lash adj.... procure a doner valve cover and cut the center portion of the top off, install, start car, adj. lash, re-install CORVETTE valve covers. Job done, no oily mess. Cost = $5.00 my .02 :cool:
