Tighten the adjusting nut until the slack is taken out of the rocker arm and pushrod. Lightly turn the pushrod with your fingers as you tighten the adjusting nut, and you should feel a point where there is a little resistance. This is called zero lash – the point where you have taken all of the excess slack out of the pushrod. Turn the adjusting nut Â½ turn past this point, giving you optimal pre-load for the rocker arm, pushrod and lifter. Follow this procedure by carefully adjusting each intake valve according to cylinder firing order.Next, we’ll adjust the exhaust valves. To do so, you need to turn the engine over until the intake pushrod moves all the way up. Rotate just past maximum lift, where the intake will begin to close. The lifter is now at the base circle, and the exhaust valve can be adjusted. Note: DO NOT go too far down (over halfway) past the point of maximum lift. If you go too far, you will be in the overlap cycle – where intake valve lash is being taken up as the exhaust valve begins to open.Rotate the exhaust pushrod with your fingers and begin to tighten the exhaust adjusting nut. When you begin to feel resistance against the pushrod, you are once again at zero lash. Tighten the adjusting nut another Â½ turn. DO NOT OVERTIGHTEN. Repeat through the firing order until the lash on every exhaust valve has been set.   <a href="http://www.cpgnation.com/.../comp-cams-how-valve-lash-adjustment-2076.html" target="_blank">www.cpgnation.com/.../comp-cams-how-valve-lash-adjustment-2076.html</a></p></blockquote><p></p>
