        Valve clearance (Cold)
        Intake side
        0.145 to 0.235 mm (0.00571 to 0.00925 in.)
        Exhaust side
        0.275 to 0.365 mm (0.01083 to 0.01437 in.)

        Tech Tips

      A Thickness of new lifter
      B Thickness of used lifter
      C Measured valve clearance
      Valve clearance
      Intake A = B + (C - 0.18 mm (0.0071 in.))
      Exhaust A = B + (C - 0.31 mm (0.0122 in.))

      Tech Tips


      • Select a new lifter with a thickness as close to the calculated values as possible.

      • Lifters are available in 29 sizes in increments of 0.020 mm (0.0008 in.), from 5.12 mm (0.2016 in.) to 5.68 mm (0.2236 in.).
