The method stays handy for catching runout issues before swapping parts and costing extra labor hours.
- Seat the three contacting tips evenly until the dial needle stops fluctuating
- Zero the gauge on a certified master ring before touching any cylinder head
- Track the highest and lowest readings to calculate total taper and out of round metrics✝️
