I believe tightening the cylinder head nuts on a Honda D14A1 engine should be done in two stages. 1. Torque 2ft/lbs 2. 47ft/lbs. Does anyone know the sequence in which they should be tightened? Barry

1. Tighten the cylinder head bolts in the sequence shown. Using the 4 step torque turn method, tighten according to the following values:

• • Step 1: All to 34 Nm (25 ft. lbs.)
  • Step 2: All to 68 Nm (50 ft. lbs.)
  • Step 3: All to 68 Nm (50 ft. lbs.)

CAUTION: Do not use a torque wrench for the following step.
Step 4: Turn an additional 1/4 turn

• Step 5: Install and tighten bolts (1-10) in sequence shown, to 41 Nm (30 ft. lbs.) .

1. Tighten bolts (1-10) again to 41 Nm (30 ft. lbs.) PLUS 1/4 turn in sequence shown.
2. Install main bearing bedplate to engine block bolts (11-20), and torque each bolt to 28 Nm (20 ft. lbs.) in sequence shown.

SPECIFICATION LOOKUPS

Cylinder head bolts are usually tightened to around 65 ft-lbs, depending on what the car is.

There's more than 4 cylinder head bolts... There's usually 10 bolts.
There's also a sequence for tightening the bolts:

cylinder head tightening order Google Search

When tightening cylinder head bolts do it in 'stages' and follow the sequence .. ie.. tighten the bolts finger tight first, then torque them up to about 25 ft-lbs. Wait 2 minutes.

Then tighten them to about 45 ft-lbs in sequence. Wait 2 minutes.

Do it again up to about 55 ft-lbs. Wait 2 minutes.

Tighten them up to 65 ft-lbs or whatever is recommended for your car.

Tightening in order/sequence pulls the cylinder head evenly onto the block. Waiting 2 minutes between stages allows a 'stretched' bolt to 'settle'.

Cylinder head torque is done is steps, if this is not followed you will end up with another leak in a very few 1000 miles. Here is the procedure:

Step 1. Tighten all 10 bolts in sequence to 14 ft/lbs (20 Nm).

Step 2. Tighten all 10 bolts in sequence to 36 ft/lbs (49 Nm).

Step 3. Tighten all 10 bolts in sequence to 49 ft/lbs (67 Nm).

Step 4. Tighten bolts 1 and 2 to 49 ft/lbs (67 Nm) again.

Use only high quality gaskets.

Tighten the cylinder head bolts to their final torque specification in two steps. Use a crisscross sequence starting with the bolts at the middle of the head and working toward the outer bolts.

1. Step 1: Tighten each bolt to 22 ft. lbs. (30 Nm).
   
2. Step 2: Tighten each bolt to 61 ft. lbs. (85 Nm).

Hope helps.

The torque angle tightening method is now valid for all engines of types 924S, 944, 944S and 944 Turbo including all earlier engines from start of 944 production. When making repairs, the following parts must be used:
Cylinder Head Gaskets
Part Number 944 104 374 14 - 924S, 944, 944S Part Number 951 104 374 01 - 944 Turbo only
Cylinder Head Nuts (12 mm high)
Part Number 999 076 028 02 - all types
Washers
Part Number 944 104 229 00 - all types
Tightening Specifications to Torque Angle Method
Tightening is done in 3 steps:
Step 1: 20 N-m (15 ft. lbs.) Step 2: 90 degrees (114 turn) Step 3: 90 degrees(1/4 turn) Important:
Sequencing must be kept for each step. Threads and bearing surfaces of nuts must be lightly lubricated with oil prior to installation. Washers must not turn while tightening. Create a reference mark if necessary.
Note:
The 12 mm high cylinder head nuts might protrude above the studs slightly on engines produced prior to Feb. 1986. In addition, new head nuts must be used at each repair.

Dont forget to apply clean engine oil to the threads of each bolt for proper torquing. Then finger tighten. Then

1. Tighten the cylinder head bolts to their final torque specification in 4 steps. Use a crisscross sequence starting with the bolts at the middle of the head and working toward the outer bolts as follows: Step 1: Tighten each bolt to 14 ft. lbs. (20 Nm).Step 2: Tighten each bolt to 36 ft. lbs. (49 Nm).Step 3: Tighten each bolt to 49 ft. lbs. (67 Nm).Step 4: Retighten only the 2 center bolts to 49 ft. lbs. (67 Nm).

1. Step 1: Tighten each bolt to 14 ft. lbs. (20 Nm).
2. Step 2: Tighten each bolt to 36 ft. lbs. (49 Nm).
3. Step 3: Tighten each bolt to 49 ft. lbs. (67 Nm).
4. Step 4: Retighten only the 2 center bolts to 49 ft. lbs. (67 Nm).

these are done in three stages 1:tighten all bolts to 25ft lbs. 2nd: all bolts to 50 ft lbs 3: retighten all bolts to 50ft lbs. the last stage is to tighten all bolts 1/4 turn more. do not use torque wrench for the last 1/4 turn hope this helps
