Valve Stem-To-Guide Clearance Measurement

WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
  1. Measure and record internal diameter of valve guides. Valve guide internal diameter is 6.0 to 6.012 mm (0.2362 to 0.2366 in.).
  2. Measure valve stems and record diameters. Intake valve stem diameter 5 mm (0.1968 in.). Exhaust valve stem diameter 5 mm (0.1968in.).
  3. Subtract diameter of valve stem from internal diameter of its respective valve guide to obtain valve stem clearance in valve guide. Clearance of inlet valve stem in valve guide is 0.03 to 0.06 mm (.0011 to.0023 in). Clearance of exhaust valve stem in valve guide is 0.04 to 0.07 mm (.0015 to.0027 in).
  4. If valve stem clearance in valve guide exceeds tolerances, new valve guides must be installed.
