2. Using a spring compression gauge (2), compress the
valve spring to 1.17 in. (29.9 mm). Compare the
tension reading to specification and replace as
needed.
Pound Force at 1.17 in. (29.9 mm) Height:
Valve Spring Tension Standard: 22—26 lb-ft
(100—116 N•m)
Valve Spring Tension Limit: 20 lb-ft (88 N•m)
3. Using a square (4), check valve spring right angle.
Use a feeler gauge to measure distance (3).
Compare measurement to specification. Replace as
needed.
Valve Spring Right Angle Range: 0.000—0.059 in.
(0.00—1.5 mm)
Installation Notes
Always use new O-rings, gaskets, and seals.
Apply clean engine oil to tappet and valve stem contact
surfaces.
Install valve assemblies with new valve seals by reversing
the order of removal.
Check valve clearance. (See "Valve Clearance Check
