To set the valves with the engine running, first adjust them so they're not  loose and clacking. tighten them til they're quiet. Then loosen them one at a time. Loosen one til it clacks, then tighten it til it's quiet, then the next til they're all quiet. Then tighten them all an additional 1/2 to 3/4 turn tighter. Then you can put on the valve covers and clean up the oil mess. There are also oil deflectors that you can buy that will deflect most of the oil to drop down into the cylinder head. Another way I have done it is to have a spare set of valve covers that I cut a 1" slot out of the top to access the adjuster nuts, adjusted the valves and then, changed the valve covers. I strongly suggest buying a manual that tells you how to set the valves with the engine off. _____________________________ Give a man a fish and he will eat for a day, teach a man to fish, and he will sit on a boat drinking beer for a life time (in reply to Chevyguy032) Post #: 2

I don't do it with the engine running any more 'cause I don't like cleaning up the oil that gets pumped all over the engine. _____________________________ Give a man a fish and he will eat for a day, teach a man to fish, and he will sit on a boat drinking beer for a life time (in reply to Chevyguy032) Post #: 4
