What are the torque specifications for Toyota 22R cylinder head bolts?
Answer:
You will need a NEW set of 10 new head bolts ($40-45). They are supposed to be STRETCH bolts, and are therefore NOT to be reused. There is a bolt pattern. Torque three times at 58 foot pounds of torque.
20/22R/RE head bolts are not torque-to-yield (stretch), and are re-usable! Torque is 55-63 foot pounds. Thoroughly clean the bolts on a wire wheel and inspect for pitting, especially in the threads and replace as necessary. It is also recommended to re-torque them after about 1,000 miles. following the torque pattern, one at a time, loosen the bolt the least amount possible, and then turn to torque spec - 55-63, although many of us who do this regularly go to 70. Oh - and don't forget the "11th head bolt" buried in the pool of oil below the distributor gear, but it should only be torqued to about 14 foot pounds.
