Project Diamond continues! Now that the engine is apart and clean we need to measure the cylinders, valves and valve guides. Proper measurements of these internal engine parts will determine the direction of the rebuild. This requires a handful of precision measurement tools to do the job properly.

The tools below are available from Common Motor, but need to be ordered via email or phone.
