Yes, there is a specific pattern for tightening the head bolts on a 22RE engine to ensure even pressure across the cylinder head. Typically, you should follow a sequence that starts from the center bolts and moves outward in a crisscross pattern. This helps prevent warping of the head and ensures a proper seal. Additionally, it's important to follow the manufacturer's torque specifications and perform a multi-step tightening process, gradually increasing the torque to the final specification.
Torque the head bolt on a 1993 Toyoto 22RE three times at 58 foot pounds of torque. The 22RE 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. ChaCha!
I am currently changing a head gasket in a 93 Toyota 22re. I'm willing to share info on the process. I had to grind one of the head bolts off to get it out, I'm also replacing the timing chain.
last i heard yes you do so it would be best if you did so.
Torque as follows 53-63 ft/lbs. in 3 steps
Imagine your head, choose the upper farthest left bolt (looking front the side) call that 1. Than the bolt directly will be 4. So your head should have bolts in this sequence:____l1234ll5678lStart with 1, than 6, 3, than 8, 5, than 2, 7, than 4. SNUG THEM ALL DOWN IN THIS ORDER BEFORE YOU TORQUE THEM DOWN!!! THIS ENSURES THE HEAD IS ON STRAIGHT SO IT WILL SEAL PROPERLY.
There are many reasons, loose head bolts- improper torque sequence- improper timing of the camshaft-poor valve seal at the seat.
Torque Value For 1987 R22, Per Haynes Manual - 58 ft lbs.
well if the 1985 did have a 22re ya it wold fit on a 1993 but since they didn't have the 22re in 1985 yet you probably have a 22r or a 20r in the 1985. i would recommend just buying a reconfigured head for the 1993 22re they are cheep like 2-400 bucks then you know its all new and will work

Which bolts are you referring to - the head bolts - or the wheel lugs?
