| Post subject: | Valve lash theory |
Considering I am working on a reasonably healthy 49K slant engine circa '72....can I assume that the cylinders that will benefit the MOST from a valve lash are the cylinders that affect the smoothness of idle quality the LEAST when pulling sparkplug wires. just to clarify, some cylinders will cause a major shake/skip when spark is removed (I would consider them major players) but some are barely noticeable when removing spark. Does this theory fly?? Thanks, nico |

The theory is sound only if those cylinder not pulling their own weight are misfiring due to their valves being held open from a deficit of lash. |

Josh is right, but it doesn't bear worrying about which cylinders will benefit more or less than which other cylinders from correct valve lash. Just adjust all the valves correctly — here's the valve adjustment procedure. |
