This is a download file that has a image inside that explains the proper ways to adjust your valves. It is very informational and you won't look at valve adjustment the same way again. The instructions are written for 6-8 cylinder engines, but the information is relatable to 4 cylinder adjusting if you know engines even a little. A valve adjustment is a valve adjustment, but this helps you do it the right way from now on.
