Re: [Chrysler300] Fw: P & G Valve Gapper for Solid Lifter Adjustment

[Mike Apfelbeck <moparmike@xxxx>]

You could use one of those tools they use to check ball joints for wear, it 
has a modified vise grip on one end that is used to grip some convenient 
solid location(such as the head of an intake manifold bolt) with a flexible 
arm attached to the dial indicator . Once the indicator is positioned over 
the rocker tip, a small lever is turned, which locks the arm in position.
Or you could figure out how many threads per inch are on the adjuster and 
determine the distance of one thread(for example 24threads per inch equals 
.0466 inch per turn) and calculate what portion of a turn out from zero 
would equal the desired lash setting.
