Data Table
The list below identifies a Vehicle, Engine, the manufacturer's recommended cold valve stem to rocker clearance (data for hot gapping, where available, is in parentheses) for both Inlet and Outlet valves in thousands of an inch (Thou or Mil), the corresponding number of Clicks for the Clikadjust, and the required socket size for the Lock-Nut across-flats (A/F).
Check that the tappet screw turns easily on its threads, otherwise the Clikadjust may falsely indicate that rocker-screw contact point.
This list is currently far from comprehensive. If your vehicle data is not here, please refer to "Calibrating the Clikadjust".
Once you have established the correct number
of clicks required for your car, please assist others by sending a message to lbcarco@lbcarco.com,
advising the data required in each column. This
list will be updated with your data.
