Remove front cylinder head cover and all 6 spark plugs.Rotate engine until the #2 piston is at TDC of the compression stroke.Install a degree wheel on the crankshaft pulley.With proper adaptor, install a dial indicator into #2 spark plug hole. Using the indicator find TDC on the compression stroke.Position the degree wheel to zero.Remove dial indicator from spark plug hole.Place a 5.08 mm (0.200 in.) spacer between the valve stem tip of #2 intake valve and rocker arm pad. Allow tappet to bleed down to give a solid tappet effect.Install a dial indicator so plunger contacts the #2 intake valve spring retainer as nearly perpendicular as possible. Zero the indicator. Rotate the engine clockwise until the intake valve has lifted .254 mm (0.010 in.). Do not turn crankshaft any further clockwise as intake valve might bottom and result in serious damage.Degree wheel should read 6 degrees BTDC to 6 degrees ATDC.
