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 ΒΌ 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

How to change head gasket


That's a pretty big job, if you're not a mechanic.
in general (I've not done one on an Aveo)
1. detach intake and exhaust manifolds from head
2. remove sparkplugs and move all wiring aside
3. Remove cover from top
4. Guessing overhead cams, remove belt/chain
5. remove head bolts.
6. pull head. I used to have a special tool that threaded into plug holes and pressed down on head studs. Otherwise, we'd end up lifting the whole car by the head and beating on it to get the head off.
7. clean gasket debris off head and block.
8. If needed send head out to be milled to flat.
9. place head gasket, add head, and torque to specs.

and the rest of what you did to get it off, in reverse order.

I am trying to remove and reinstall the cylinder head of my 1994 S 10 pickup truck. I have removed the nuts and bolts holding the intake and exhaust manifolds to the head but I am having some dificulty in...


Leave the exhaust manifold attached and just push it away. Remove the head bolts and make sure all vacuum lines and fuel lines and water lines are disconnected. Make sure you have the head resurfaced before reinstalling and buy new head bolts. Remember to torque the head bolts to spec. But it seems to me like you pretty much got the hang of it.

How to replace head gasket 1998 Lumina


Cylinder Head Removal & Installation 3.1L Engine To Remove:
NOTE: With some minor variations, this procedure can be used on both the left and right cylinder heads.
  1. Raise and safely support the vehicle.
  2. Drain the engine coolant and the engine oil. Lower the vehicle.
  3. Remove the upper and lower intake manifolds.
  4. Remove the rocker arms and pushrods.
  5. Remove the exhaust crossover pipe.
  6. Remove the engine mount strut bracket.
  7. If removing the left side (front) head, remove the dipstick tube.
  8. Tag for identification, then remove the spark plug wires.
  9. Remove the spark plugs.
  10. Remove the exhaust manifold using the procedures found in this section.
  11. Remove the eight cylinder head bolts, then remove the cylinder head. There are locator pins that align the head to the block. Pull upwards on the head to disengage the pins, then remove the cylinder head to a suitable work area.
  12. If the head is be overhauled, remove any remaining components such as the engine lift hook, the fuel line bracket bolts, the engine coolant temperature sensor, etc., as required.
Position a new gasket, install the head, then tighten the bolts in the sequence shown (3.1L engine shown) 93173g43.gif

To Install:
NOTE: If the head gasket failed, determine the cause. Gasket failure is caused by the following conditions: improper installation; overheating due to a failure in the electric cooling fan system or a leak in the cooling system; loose or warped cylinder head; missing, off location or not fully seated locator dowel pins; low torque on the cylinder head bolts; warped block surface; scratched or gouged gasket surfaces; excessive intake manifold torque and even cracked engine block tapped holes.
  1. Clean all parts well. Remove all foreign material to the bare metal. Do not use a motorized wire brush on any gasket sealing surface. It is good practice to use the proper size thread-cutting tap to clean the threaded bolt holes in the block. This helps assure an accurate torque reading.
  2. Place a new head gasket on the clean engine block deck surface. Many gaskets will have some sort of marking denoting TOP or THIS SIDE UP. Make sure the gasket sits flat and is not hung up on the locator dowel pins. Use no sealer on the head gasket.
  3. Carefully set the cylinder head in place, using care not to damage the gasket. Make certain that the head engages the locator dowel pins that properly position the head.
  4. The bolts should be very clean since dirt built-up on the bolt threads makes it difficult to get an accurate torque reading. These are 'torque to yield' bolts which stretch a small amount when tightened; new bolts are always recommended. On a used vehicle, especially a high-mileage vehicle, it may be difficult to determine if the heads have been removed before and how many cycles the bolts have been removed and tightened. New bolts should be part of any cylinder head service. Use GM Sealer #1052080, or equivalent, on the threads of the head bolts and install all eight bolts, finger-tight.
  5. With an accurate torque wrench, tighten the bolts gradually, in sequence, working from the center outwards. Final torque should be 33 ft. lbs. (45 Nm), plus an additional 90 degrees (1/4-turn). A torque angle meter is recommended.
  6. Install the remaining components in the reverse order of the removal process.
