PET CLEARANCE
(1) Check engine oil level, adjust as necessary.
(2) Warm engine to operating temperature
(approx. 80ÉC, 176ÉF).
(3) Remove the cylinder head cover (Refer to 9 -

camshaft, at the tappet to be tested, is at it's base
circle (camshaft nose must point upward) (Fig. 20).
NOTE: Do not use a tool that will mar or damage
the tappet surface. If applied pressure is too strong
the tappet will appear to drop, but what happens is,
the valve opens.
(5) Use a pressing tool and apply pressure to the
tappet by hand (Fig. 20).
(6) If the tappet drops faster in comparison to the
other tappets, remove the camshaft and replace the
tappet.
