The head bolts are done in 3 stages: first stage is 20 ft.lbs, second stage is 50 ft.lbs and the third stage is an additional 90 degrees or 1/4 turn.This is the sequence.
14 10 6 2 3 7 11 15
17 9 1 8 16
13 5 4 12
The rail above the valve springs must be the rocker arm shaft. The bolts on it are torqued to 40 ft.lbs. The intake is torqued to 31 ft.lbs. Hope this helps.

Toyota 2c. I need cylinder head and flywheel Torque settings

USE NEW BOLTS...
Torque sequence:
You're driving a diesel single cylinder head engine. Engine head torque has to be done in specific order and stages if not can warp head or break bolts. Suggest you get torque sequence and torque specs from your Toyota dealer, they can give you correct answer. Don't trust answers on here, if you choose wrong specs. could end up messing up head.

!st thing is get the revised head gasket (used on 1993 up) for this engine from VW or Felpro, always use new head bolts or a repeat failure will occur.

HOW TO FIX A BLOWN HEAD GASKIT?


Buy a gasket kit for the upper end. Remove the valve cover intake and exhaust manifolds. Remove the head bolts. Remove head and clean up block from old gasket material. Take the head to a machinist and make sure that it is not warped. If it is warped either replace the head with a new one or have it machined true. Install new gasket and get torque specs with new head bolts and follow torque sequence using the correct torque specs. Clean exhaust, intake and valve cover of old gaskets. install new gaskets and torque according to specifications.

Need to find specks on cylingder head for 1996 toyota tercel


The cylinder head bolt torque is a 2 step process.

First: Torque all of the bolts to 45 Nm (450 Kgf-cm or 33 ft lbs.)
Replace any head bolt that will not torque to the above specs.

Second: after all ten bolts are torqued to the above specs, the head bolts are then "Torqued to Distance"...

Starting at the center bolts, retorque all ten bolts an additional 90 degrees.

Hope this helps, the graciousness of a FixYa rating would be greatly appreciated.
