I. Need. Help. With. Cam bolts. And head bolts


Part 1 of 3: Getting to the head bolts

Materials Needed
  • Eye protection
  • Gloves
  • Oil and coolant drain
  • Parts cleaner or brake cleaner
  • Shop rags
  • Socket set and ratchet1: Drain the oil and coolant. Put on your eye protection and gloves and drain the oilfrom the vehicle.
    Make sure the vehicle can not be started by removing the negative cable from the battery. Next the coolant will need to be drained so it does not leak when the head bolts are loosened.
    Step 2: Clean valve cover. Use some of the parts cleaner or brake cleaner to clean up the valve cover and as much of the cylinder head as is reasonable.Remove valve cover. If necessary, remove other components to make the valve covers accessible, and start removing the bolts from the valve cover.
    Once all bolts are removed carefully removed the valve cover from the cylinder head. If any valve cover gasket material remains, remove it at this time and clean any excess oil from the edges. Set the valve cover aside carefully as it will be reused with a new gasket once repairs are completed.

    Part 2 of 3: Pushrod engine head bolt removal

    Materials Needed
    • Head bolt socket (if needed)
    • Numbered cardboard
    • Rubber hammer
    • Socket set and ratchetStep 1: Rocker arm and rocker removal. A pushrod engine has long pushrods that protrude through the cylinder head and attach to the rocker rail.
      The rocket arm will need to be loosened first. Many manufactures have a specific sequence for removal of the rocker arm bolts. After the rocker arm is removed, the rockers will be unbolted.
      Set all rocker arms aside in the order they were removed as they should go back to the cylinder they were removed from.Step 2: Remove the pushrods. Remove the pushrods one at a time from the cylinder head.
      Put them into a numbered piece of cardboard as the pushrods will go back into the same slot they came from.Step 3: Loosen head bolts. Use the ratchet begin to break the cylinder head bolts loose.
      Each bolt will be loosened but not removed. Loosen all of the bolts before removing any of the the bolts all the way.
      Step 4: Remove the bolts. Place each bolt through a numbered hole in the cardboard in case the head bolts are different lengths so they can be installed back into the proper hole.
      The bolts may require a special socket depending on the manufacture.
      Step 5: Lift off the cylinder head. Once all bolts are removed, lift up on the cylinder headgently; the head should come free easilyIf the cylinder head sticks, lightly use a dead blow or rubber mallet to tap the cylinder head to be able to remove it. Set to the side in a safe area.
      • Warning: Cylinder head bolts have a specific sequence that is used when removing them. Consult the manufacturer's specifications for the proper removal sequence for the engine being worked on.

      Part 3 of 3: Overhead cam head bolt removal

      Material Needed
      • Socket set and ratchetStep 1: Remove the timing cover. The timing cover will need to be removed to gain access to the timing belt or chain.
        This is necessary because the cam shaft sits in the cylinder head and is attached to the crankshaft with either a timing belt or timing chain.
        Step 2: Time the engine to remove the belt. The engine will need to be timed to avoid damage when the timing belt is removed.
        Each engine is different and will have its own procedures to time. There should be marks on the camshaft and crankshaft that will be aligned to set the timing at top dead center (TDC)Step 3: Remove the timing belt. The timing belt tensioner will be removed or released to take the tension off the belt.
        Once the belt is loosened, it should be able to be slipped of the camshaft in the cylinder head.Step 4: Remove the head bolts. Every engine will have its own procedures for the order that the head bolts are removed or tightened.
        Loosen head bolts ¼ turn each in the order specified, which may require a special socket. Once all the bolts have been loosened they may be removed one at a time. The bolts must be organized or marked in case they are different lengths.
        Step 5: Remove the cylinder head. Once all the bolts are removed, the cylinder head may be removed from the engine. If it is stuck, tap lightly on the side of the head with a rubber hammer to loosen the cylinder head.
        • Warning: Most head bolts are torque-to-yield. These head bolts are single use only and once removed must be replaced. Torque-to-yield head bolts stretch when they are torqued to allow them to tighten properly and repeated application can cause the head bolt to break.
        Removing the head bolts can seem like a daunting process

Need to remove cilinderhead from a chevrolet trailblazer 2003


below are the instruction you well need to remove head .....good luck Removal Procedure
  1. Remove the air cleaner element.
  2. Remove the air cleaner outlet resonator. .
  3. Remove the powertrain control module (PCM) and engine wire harness bracket and related hoses and connections.
  4. Remove the generator.
  5. Remove the intake manifold.
  6. Remove the exhaust manifold. Do not remove the exhaust pipe from the manifold. Only have the manifold pushed off to the side of the engine.
  7. Position the A/C line out of the way towards the front of the vehicle.
  8. Disconnect the following cross-vehicle engine wiring harness connectors:
  9. • Engine coolant temperature sensor • Manifold absolute pressure (MAP) sensor • Ignition coils • Harness clamps at power steering pump • Wiring harness fastener at the right front inner fender • Throttle body • Camshaft sensors • Camshaft actuators • Fuel rail • Heated oxygen sensor (HO2S)
  10. Set aside the cross-vehicle engine wiring harness on the left side of the vehicle.
  11. Remove the camshaft cover.
  12. Partially drain the cooling system.

  13. Before performing one of the top dead center (TDC) procedures, break loose both the exhaust and intake camshaft sprocket bolts. Use a 25 mm (1 in) open end wrench on the camshaft hexes to hold the camshaft from turning. DO NOT remove the bolts.
  14. Perform one of the following methods for the service timing procedure.
  15. First Method--Rotate the engine clockwise by hand to TDC on the compression stroke by using a piston TDC indicator tool and/or dial indicator in the number 1 cylinder.
  16. First Method (continued)--The TDC indicator tool graduation marks on the shaft should note top of the piston stroke.
  17. First Method (continued)--When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats.
  18. Second Method--Rotate the crankshaft in the engine rotational direction clockwise until the number 1 piston is at TDC on the compression stroke. The word Delphi on the exhaust camshaft position actuator will be parallel with the cylinder head to cam cover mating surface. When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats. A 0.005 inch feeler gauge should not slide under the straight edge (1).
  19. Use a white paint pen or equivalent to place a reference mark on the harmonic balancer to the front cover for alignment purposes.
  20. Lower the vehicle.
  21. Important: If the timing is correct (TDC compression stroke number 1 cylinder), the camshaft flats will be in the up position.
    Install J 44221 to the back of the camshafts.
  22. Remove the upper timing chain guide to the cylinder head.
  23. Clean the timing chain and gears with brake cleaner or suitable solvent. Use a white paint pen or equivalent to place a reference mark on both timing gear sprockets and the timing chain to mark location prior to disassembly. It is recommended that the paint marks be in the 12 o'clock position.

  24. Install EN-48464 . It is important to install the tool with the proper orientation and to ensure that it is seated square against the timing chain and against the timing cover center bolt.


  25. The narrow ramp of the wedge tool needs to be placed so that it faces the timing chain.
  26. The wedge tool should be lightly seated using a couple of very light taps with a small plastic or brass hammer. The wedge tool will be fully seated against the tensioner after it moves about 25 mm (1 in).
  27. Once the tool is correctly installed, unscrew the handle and remove the handle

  28. Remove both upper cylinder head access hole plugs from the front of the cylinder head.
  29. Remove the 1 long and 2 short cylinder head bolts next to the exhaust and intake timing chain tensioner shoes and discard the bolts.
  30. Remove both upper timing chain tensioner shoe bolts.
  31. Remove the exhaust and the intake camshaft sprocket bolts. Discard the bolts.


  32. Carefully remove the exhaust and intake camshaft sprockets with the timing chain from the exhaust and intake camshafts. The illustration shows the exhaust camshaft sprocket already removed.


  33. Remove the sprockets from the chain, tie a piece of mechanic's wire on the timing chain and let it drop.


  34. Before removing the cylinder head bolts, use a drift punch and hammer to shock the bolts. This will ensure that the cylinder head bolts will not strip out the threads in the engine block or break. If a bolt breaks during engine disassembly, EN-47702 is available to assist in the removal of the remaining bolt segment.
  35. Remove the cylinder head bolts. Discard the bolts.
  36. Remove the cylinder head.
  37. Place the cylinder head on a flat, clean surface with the combustion chambers face up, in order to prevent damage to the deck face.
  38. Remove the cylinder head gasket.
  39. Discard the gasket.
  40. Remove all remaining gasket material from the engine block.
  41. Inspect the cylinder head gasket mating surface on the engine block.
  42. Clean and inspect the cylinder head.
  43. Disassemble the cylinder head if necessary.

Fig. Cylinder head bolt tightening sequence-2.7L engine
  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
