Valve Guide Servicing

  1. Check valve guides for wear. If replacement is necessary, press out old guide using drift tool (5218). Ream hole in cylinder head to oversize class 1 or 2.
  2. Heat cylinder head to 300° F (150° C) and cool valve guides to -95° F (-70° C). Press valve guides into cylinder heat quickly (3-4 seconds, because of high temperature loss.
  3. Using drift tool (5108) for intake or (5109) for exhaust, press in new guides. Using reamer tool (5224), ream guides to .3150-.3158" (8.00-8.02 mm). Check for burrs and be sure valves move freely in guides. Using drift tool (5218), install valve guide seals
