Fitting
–  Oil the new guides and, using the valve guide tool -T20035-, from the camshaft side, insert them as far as the collaret into the cold cylinder head.
  Note
Once the collar of the guide is under pressure, the insertion pressure should not be increased above 10 kN (approx. 1.0 t), if so the collar may rupture.
–  Ream the valve guides with the valve guide reamer -T20067-. To do this, taladrina (drilling oil) must be used.
–  Rework valve seats → Chapter.
