Ford windsor 351 valve adjustment

There is no mech. adjustment that you can 'dial' in. The lifters are hydrolic, and self adjust. Oil pressure keeps the lifter "inflated" and transfers motion through a push rod, across a fixed rocker, and opens the valve. A ticking sound comming from this area might be the result of many things. Worn lobes on cam shaft, worn contact surface between lifter and cam, a dirty lifter that fails to pump up, a bent push rod.

These are the more likely things to look at first. The list could go on...

If you are experiencing any back firing through intake or out the exhaust, disregard the above paraghaph. It may be time for a valve job. Be careful though, a valve job on a worn or high mileage engine may create problems of blowby on piston rings.
