OVERHEAD VALVE TORQUE SPECIFICATIONS

The torque specifications listed in this chart are to be used for replacing components after disassembly, not for

checking an existing engine bolt torque. Checking a torque value on a new or used engine may be lower due

to torque relaxation that occurs on all engines from thermal expansion and contraction. However, sufficient

clamping force exists and a re-torque is not necessary.

Specifications below ten ft. lbs. or ten Nm torque are listed only as in. lb. measurements to encourage the use

of an inch pound torque wrench for greater torque accuracy.
