Adjusting Corvair valves is a snap!

An easy way to adjust Chevy Corvair valves without making a big mess: split a stock valve cover in half, that will catch the oil ( if you need a used valve cover, check our website www.rafeecorvair.com under used parts, we have them in stock, as well as many other gaskets to finish the job) ....If you are doing a maintenance valve adjustment, install your oil catchers on both sides, let the engine warm up, and starting at either end, loosen the nut until the rocker arm starts clattering/ knocking/ ticking (LOL), let it do its thing for several seconds, then re-tighten til the noise quiets down, stop and then go 1/4 turn more. Some even go 1/2 turn to 3/4 turn. Myself, I do 1/4 turn to 1/2 turn and it works. If the engine is new, you can do this 2 different ways: cold, as outlined in the shop manual, or with the engine running, as I prefer. Make sure all the rocker arms are tightened, but leave some small amount of play between the valve stems and the rocker arm tips, so the lifters can pump up. I want to explain this the easiest way that I can, not too technical, so everybody can follow. If the engine is new, I normally let it run for 20 to 30 mn, I want this baby to be hot, so the lifters can pump up ./ fill with oil. Then I start tightening 1 rocker arm at a time, starting at either end. Just take the clatter/ knocking away, and no more. When you are done doing all that to the 12 rocker arms, now you are gonna adjust one at a time, by loosening each one, let the clatter ...
