I need rocker arm and t post identification and indexing info and intake manifold torque specs/tightening sequence for a 1976 500 cadillac eldorado thanx.

The 2014 Chevy Spark intake manifold torque sequence and torque specs depend on the engine type. Here are the torque specs and sequence for each engine type:
1.0L Engine:

• Step 1: Tighten the bolts to 44 inch-pounds (5 Nm).
• Step 2: Tighten the bolts to 89 inch-pounds (10 Nm).
• Step 3: Tighten the bolts to 18 lb-ft (25 Nm).

Torque sequence: 8 4 1 5 9 7 3 2 6 10
1.2L Engine:

• Step 1: Tighten the bolts to 44 inch-pounds (5 Nm).
• Step 2: Tighten the bolts to 89 inch-pounds (10 Nm).
• Step 3: Tighten the bolts to 18 lb-ft (25 Nm).

Torque sequence: 8 4 1 5 9 7 3 2 6 10
It's important to follow the torque sequence and torque specs carefully to ensure that the intake manifold is properly secured and sealed. Over-tightening or under-tightening the bolts can cause leaks or damage to the engine.

I could not answer this any better than what I have found online. Here is a guy that has posted removal and re-installation in great detail as well as great photos.

I give all the credit for this answer to the poster.

Tightening sequence would be to tighten from the center most bolts to the outer most bolts.
Intake Upper Bolts = 18 lb.ft.
Intake Lower Bolts = 10 lb.ft.
Exhaust Manifold Nut = 12 lb.ft
Exhaust Manifold pipe = 22 lb.ft.
Exhaust Manifold Heat Shield = 18 lb.in.
Rocker Arm Torque Nuts = 18 lb.ft.

Hope this helped you ?? if you need more info, get back to me.....

Install the cylinder head bolts. Starting at top center, tighten all cylinder head bolts in sequence as shown in illustration, using the Cylinder Head Bolt Wrench (09221 - 32001) or equivalent. Repeat the procedure, re-tightening all cylinder head bolt to the specified torque. (torque spec is Cold Engine 105-115 Nm (76-83 ft lb) )
. Install the timing belt tensioner pulley.
. Install the timing belt on the camshaft sprocket, making sure that the tension side is tightened by turning the camshaft sprocket in reverse, all timing marks are in alignment.
. Adjust the timing according to "Timing Belt"
. Install the rocker cover and tighten the bolts to the specified torque. Tightening torque: Rocker cover belt:

2.5-3.5 Nm (25-35 kg.cm, 2-3 ft. lbs.)

. Install the timing belt cover.
Install the new intake manifold gasket and the intake manifold. Tighten the nuts and bolts to the specified torque.
Install the new exhaust manifold gasket and the exhaust manifold. Tighten the exhaust manifold attaching nuts to the specified torque.
. Install the surge tank and tighten the nuts bolts to the specified torque.
. Install the power steering oil pump and bracket.
. Install the ignition coil.
. Install the air intake hose.
Connect the vacuum hose, fuel hose and water hose.
. Install breather hose.

- Position the rocker arms in their original locations and tighten to the proper specifications.
- Install lower the intake manifold attaching bolts. Apply sealant or equivalent thread locking compound to the threads of bolts. Tighten the vertical bolts first, then the diagonal bolts to 115 inch lbs. (13 Nm).
- Install the upper intake manifold and tighten the mounting bolts to 18 ft. lbs. (25 Nm).

Hope helps (remember to rate this).

3.4L Engine To Remove:

1. Remove the lower intake manifold.
2. Remove the exhaust crossover pipe.
3. If removing the right cylinder head, remove the catalytic converter from exhaust manifold.
4. If removing the left cylinder head, remove the engine oil dipstick and tube.
5. Remove the rocker arms and pushrods.
6. Remove and discard the cylinder head bolts.
7. Remove the cylinder head.
8. Clean the mating surfaces on the following items:
   • Cylinder head
   • Cylinder block
   • Intake manifold
9. Clean the cylinder block bolt threads.

NOTE: During disassembly, keep the valve train components together for proper location during assembly.
To Install:
NOTE: Coat the cylinder head bolt threads using thread sealer.

1. If removed, install the following components:
   • Exhaust manifold
   • Accessory studs
   • Spark plugs
2. Place the cylinder head gasket in position over the dowel pins. Ensure that the THIS SIDE UP note is showing.
3. Install the cylinder head. Cylinder head torque sequence ’99-‘00
   
   Cylinder head torque sequence ’01-05
   
   
4. Install the new cylinder head bolts.
   • Tighten the cylinder head bolts a first pass to 44 ft lb (60 Nm).
5. Tighten the cylinder head bolts in sequence an additional 95 degrees.
6. Install the intake gasket.
7. Install the pushrods and rocker arms.
8. Raise and support the vehicle.
9. Install the catalytic converter and dipstick tube and indicator if removed.
10. Lower the vehicle.
11. Install the exhaust crossover pipe.
12. Install the intake manifolds.
13. Connect negative battery cable.
14. Fill the cooling system.

2.2L Engine & 2.4L Engines
These engines are not equipped with rocker arms. The camshafts directly actuate the valves.

3.1L Engine & 3.4L Engines
When install or connect the check the following:
- Pushrods and the rocker arms. Torque the bolts to 24 ft. lbs. (32 Nm). - Rocker arm cover using a new gasket. Torque the rocker cover bolts to 89 inch lbs. (10 Nm).
- Heater bypass pipe. Torque the screw at the water pump to 106 inch lbs. (12 Nm), the bolt at the cylinder head corner to 18 ft. lbs. (25 Nm) and the nut to 18 ft. lbs. (25 Nm).


About the INTAKE MANIFOLD...
- Intake manifold nuts and bolts and tighten to 89 inch lbs. (10 Nm)
- Pushrods and rocker arms. Torque the bolts to 89 inch lbs. (10 Nm) plus an additional 30 degree turn. - Lower intake manifold. Apply sealant to the threads of the bolts and torque the bolts to 115 inch lbs. (13 Nm).
