Lash Valve lash by definition is the gap between the rocker arm and the tip of the valve stem. The rocker arm may have ground radius or a steel roller, and the valve tip is ground perpendicular to the valve stem.
When to use bolt torque and preload calculator?
The Bolt Torque & Preload calculator can be used to calculate the torque required to achieve the desired preload on a bolted joint. See the reference section for details on the methodology and the equations used.
How do you measure the height of a valve spring?
Using a good mechanic’s ruler, measure the spring from where it meets the bottom of the retainer to where it sits on the cylinder head. DO NOT INCLUDE THE THICKNESS OF THE SHIMS. Use a valve spring height micrometer. Much more precise than a ruler, the micrometer replaces the spring itself.

How to Assembly a Ford 4.6L engine step by step?
Torque the main caps with a 13-mm socket to 27 to 32 ft-lbs, and then to 85 to 95 degrees on the torque-angle gauge. Install the dowel pins and hammer them into place. Next, install the cross bolts (also called side bolts) from the outside and torque them to 20 to 24 ft-lbs, and then 85 to 95 degrees. The Windsor block has no jackscrew adjusters.
