I'm losing power and showing low oil pressure. If I stomp on her she runs ok until I come out of third gear. Takes a long time to get from 50 to 70 and it feels like the truck is giving me everything she...


Check compression in each cylinder., sounds as if it might be piston rings.oil thins as it warms so the drop in pressure seems to point to loss of compression .i take it it doesn't blow smoke out of exhaust?

Fig. 13: Head bolt torquing sequence-1970-83 models

After repair job, temporarily install and tighten the two center (right and left) cylinder head bolts to 14 ft. lbs. (18 Nm).

Install the camshaft sprocket together with the timing chain onto the camshaft. Make sure that the marks made earlier, line up. If the chain will not stretch over the sprocket, the problem lies in the tensioner. Refer to the Timing Chain removal and installation procedure for the timing procedure, if necessary.

Install the cylinder head bolts. Note that two lengths are used. Tighten the bolts in sequence.
1970-71 models:
Tighten the bolts to 33 ft. lbs. (43 Nm)
Tighten the bolts to 47 ft. lbs. (61 Nm)

1972 models:
Tighten the bolts to 47 ft. lbs. (61 Nm)
Tighten the bolts to 55 ft. lbs. (71 Nm)

1973-83 models:
Tighten the bolts to 30 ft. lbs. (39 Nm)
Tighten the bolts to 44 ft. lbs. (57 Nm)
Tighten the bolts to 54-61 ft. lbs. (70-79 Nm)

To complete the installation, reverse the removal procedures. Adjust the valves to a preliminary COLD clearance of 0.2mm for the intake and 0.25mm for the exhaust. Operate the engine until it is at normal operating temperature, retighten the head bolts (loosen them slightly and retighten to the final torque figure) and adjust the valves to the HOT clearance specifications.

Hope this helps; remember to rating this answer and leave some testimonial comment about this.

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Drain the cooling system.
  3. Properly relieve the fuel system pressure.
  4. Remove or disconnect the following:
    • Negative battery cable
    • Powertrain assembly
    • Intake manifold
    • Cam covers
    • Harmonic balancer
    • Timing chain front cover
    • Oil pump
    WARNING
    Align all timing marks before performing the next step.
    • Chain tensioner from the timing chain
    • Cam sprockets
    NOTE: The timing chain remains in the chain case.
    • Timing chain guides, access for the retaining screws is through the plugs at the front of the cylinder head
    • Water crossover
    • Exhaust manifold
    • Cylinder head bolts by reversing the torque sequence
    • Cylinder head and discard the gasket
    WARNING
    With the camshafts remaining in the cylinder head some valves will be open at all times. Do not rest the cylinder head on a flat service with the cylinder face down, or valve damage will result. NOTE: Clean all gasket mating surfaces. Clean the head bolt holes in the crankcase. WARNING
    Be careful when cleaning aluminum gasket surfaces to prevent damage to the sealing surfaces.
  5. Check the cylinder head for warpage; it must be less than 0.002 in. (0.05mm). If the cylinder head was resurfaced, the dimension between the combustion chamber gauge pad and the deck surface must be at least 10.5mm. To install: NOTE: Refer to Section 1 of this manual for the cylinder head torque sequence illustration. The illustration is located after the Torque Specification Chart.
  6. Install or connect the following:
    • New cylinder head gasket
    • Cylinder head, lubricate the bolts with engine oil
  7. Torque the M11 bolts, in sequence, as follows:
    1. Step 1: 22 ft. lbs. (30 Nm).
    2. Step 2: Turn an additional 60 degrees.
    3. Step 3: Turn an additional 60 degrees (total 180 degrees).
  8. Torque the M6 bolts to 106 inch lbs. (12 Nm).
  9. Set the camshaft timing
  10. Camshaft guide bolt access hole plugs in the cylinder heads. The plugs should be seated and snug
  11. Install or connect the following:
    • Intake cam covers
    • Oil pump
    • Timing chain front cover
    • Harmonic balancer
    • Cam sprockets
    • Chain tensioner to the timing chain
    • Timing chain guides
    • Intake manifold
    • Water crossover
    • Exhaust manifold. Torque the nuts to 22 ft. lbs. (30 Nm) or the bolts to 18 ft. lbs. (25 Nm).
    • Powertrain assembly
    • Negative battery cable Fig. 1: Minimum head resurface dimension 7922vg04.gif

  12. Fill the cooling system.
  13. Evacuate and charge the air conditioning system.
  14. Run the engine and check for leaks.

  1. Thoroughly clean and dry the mating surfaces of the head and block. Check the cylinder head for cracks, damage or engine coolant leakage. Remove scale, sealing compound and carbon. Clean the oil passages thoroughly.
  2. Place a new head gasket on the cylinder block over the locating dowels.
  3. Inspect the cylinder head bolts for necking (stretching) by holding a straightedge against the threads of each bolt. If all of the threads are not contacting the straightedge, the bolt should be replaced. New head bolts are recommended.
    WARNING Due to the cylinder head bolt torque method used, it is imperative that the bolt threads be inspected for necking (stretching) prior to installation. If the threads are necked down, the bolt should be replaced. Failure to do so may result in parts failure or damage.
  4. Lubricate the bolt threads with clean engine oil, then install them.
  5. Torque the head bolts in the sequence shown in the illustration, utilizing the following steps and tightening values:
    1. Step 1: bolts 1 through 8: 35 ft. lbs. (48 Nm).
    2. Step 2: bolts 1 through 8: 55 ft. lbs. (75 Nm).
    3. Step 3: bolts 1 through 8: 55 ft. lbs. (75 Nm).
    4. Step 4: bolts 1 through 8: plus 90 degree turn using a torque angle meter.
    5. Step 5: bolts 9 through 11: 21 ft. lbs. (28 Nm).

  6. Install or connect the following:
    Camshafts, timing chain and sprockets Water connections to the cylinder head Valve and timing chain covers Crankshaft damper and torque the center bolt to 125 ft. lbs. (170 Nm) Lower intake manifold and intake plenum Exhaust manifolds Accessory drive belts Negative battery cable
  7. Fill the cooling system to the proper level.
  8. Start the vehicle, check for leaks and repair if necessary.

HI. IT DOSN'T MATTER YOU HAVE TO START STRIPPING IT DOWN BECAUSE WHEN YOU HAVE 2 CYLINDERS THAT ARE AT 70 lbs THEY CAN'T FIRE RIGHT. SO WHEN YOU ARE AT A IDLE THOSE 2 ARE DEAD CYLINDERS UNTIL YOU BRING THE RPM's UP AND THEN THEY WILL FIRE. SO START AT THE TOP OF THE MOTOR AND WORK YOUR WAY DOWN. IF IT WAS ME WITH 220,000 ON IT I WOULD TAKE IT OUT ARE DO A MOTOR JOB ON IT. THANKS JIMBO I HOPE THIS HELPS YOU.
