What is the cylinder head bolt torque settings fir a 4g69 mitsubishi engine ?


BOLT INSTALLATION


Apply engine oil to the thread of the bolts and to the washers.
Tighten the bolts to the specified torque, using the tightening sequence shown.
Tightening torque: 54 ft-lb +/- 2 ft-lb
Loosen all bolts fully in the reverse order of tightening.
Re-tighten the loosened bolts to the specified torque in the tightening sequence shown.
Tightening torque: 15 ft-lb +/- 1 ft-lb
This step is to make it easier to ensure you are making 90 degree turns. Make a paint mark across each bolt head and cylinder head.
Tighten the cylinder head bolts 90 degrees in the specified order.
Tighten the bolts another 90 degrees in the specified order and check that the paint marks on the cylinder head bolts are aligned with the paint marks on the cylinder head.

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.

How to change head gasket


Unplug all wires and hoses connected to the cylinder head and remove the head cover. You may need to remove the A/C fan to be able to clear it of the studs on the engine block.2 Set the motor to "top dead center," or TDC. Remove the #1 cylinder's spark plug as well as the valve cover so you can observe the springs. Insert a screwdriver into the open spark plug hole, and rotate the motor by hand, counter-clockwise. When the #1 cylinder is on its intake stroke, watch the screwdriver. Turn the motor very slowly until the screwdriver reaches its highest point. Remove the screwdriver. Slide off the timing belt, and be sure you do not rotate the motor any further.3 Remove the head bolts in order, and double check that no coolant lines are still connected. Lift the cylinder head out. It will be very heavy--this is where you'll likely need the help of another person. Remove the old head gasket. 4 Drain the oil from the cylinder head. Clean the pistons, valves, headbolt holes and all other parts with degreaser and a toothbrush. Wipe down with a paper towel when finished.5 Set the new head gasket into the engine block, lining it up correctly. Carefully place the cylinder head back in, on top of the head gasket. Soak the headbolts in oil to lubricate them, then replace them. Tighten each bolt until it is snug--no further.6 Start the torquing sequence, following the directions in your Honda's manual. In most D-series cars, you need to torque each bolt to 22 foot-pounds, then all to 53 foot-pounds. Be certain to follow the correct torquing sequence as indicated in the manual, or you could warp the head.7 Reinstall the timing belt and reconnect all wires and coolant lines.

      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

    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

    1995 Plymouth Acclaim Cylinder Head Removal


    Honestly... If you are really not that good at mechanical issues you probably should take it in... Not to be mean but the head needs to come off in a bolt sequence and reinstalled in a bolt sequence with the correct torque... The passenger motor mount,exaust,wire harness,valve cover,head boltscoolant hoses,throttle cable and many more items need to be removed......Also NOTE:... slip and tuck head gasket jobs are NOT advisable and ussually result in doing the job twice over..... The heads have a tendency to warp and also crush in the gaskets over time....The head should be checked for warpage. Also a good time to do the valves and replace seals.......in the end if you are not experienced and do not have someone around that knows aboput the job at hand you may want to have the job done by a tech... For fun grab yourself a Chiltons manual and read through........

    Good luck
