They come off with the head. You only need to remove them if you can't get a socket into the head bolts.

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

How do I remove conrod from the crank shaf?


Drop the oil pan. Unbolt the connecting rod bearing cap and remove. That will free the connecting rod from the crankshaft. However, to remove the connecting rod from the engine you must
completely remove the crankshaft to pull it out from the bottom, or remove the cylinder head to remove it from the top.

Tata indica Timing marks


On. An Indica petroll or diesel there aren't aany timing marks as to say, firstly remove cylinder head, then attach a power bar or ratchet with socket to to bolt on crank shaft pulley. Rotate the engine anti-clockwise until piston one is at TDC (highest point it can go). Then at Te front of engine halfway down the block where engine meets bell housing there is a hole to. Insert a 8mm long bolt, this will lock the crankshaft. On the head on the cam shaft end cap is a hole, insert a screwdriver to fit and rotate cam with. A ratchet until the screwdriver slots in place and the cam cannot move. Replace the head, torque the bolts, fit the timing belt and tension it. Once this is done remove the locking bolt and screwdriver, Replace the cam-tappet. Cover and start the engine

Blown head gasket needs to be replaced.... Whats the best way to get the head off? do i need to take the intake and exhaust manifolds off after the head is off?? its dohc on a 2.0L......also do i need to...


The intake and exhaust manifols are both attached to the cylinder head. Sneaking the head off withboth attached, is done, but you really want to know why that gasket went out. I would suggest removing both manifolds after you get the head out, and bringing the head in to a good engine machine shop, for surfacing and pressure testing. You will need to remove the cams. Make very sure that all cam caps go back on in the same position, as these are align bored, and are not interchangeable. Does your engine run hot? Is that why the gasket failed? If so adress that too, or you will be taking this journey again. Good luck, and contact me if you have any more questions. Buy one of those Haynes manuals, unless you have access to a good online repair data base.

I'm in the middle of removing the head cylinder on a 95 toyota previa and I'm having trouble trying to get the chain out from the cam gear!is there a way of getting it off without having to take off the...


Dont remove the cam gear until you remove the crank shaft bolt.If you turn the crank with out the cam gear in place you may bend some valves.And damage the head,or a piston as well.
You can use a bar, and a socket on the crank bolt, if it clears everthing and rests on the frame work,then engauge the starter,this will loosen the crank bolt,but dont start the engine.Just a few hits on the key.Stand clear of the bar,!You may have to heat the bolt head a bit,as well.The bolt may have had locktite installed on the threads.Have the battery fully charged.

How to replace a broken timing belt


Daewoo has interference engines in them, so if the timing belt broke while the engine was running, you will need to replace half of the valves which were bent when the pistons crashed into them when the cams stopped turning and the crank shaft continued to turn. Minimum of $700-1000.00 (usually more). If you do it all yourself and the valve guides are not damaged, still at least $400.00 worth of parts to fix. Pull plastic air dams around bottom of engine on front and right side . Support engine with jack. Drain antifreeze from engine and radiator. remove air filter housing and serpentine belt. remove front engine mount. remove cam belt cover. remove broken cam belt and check cam tensioner bearings and idler bearing as well. They are usually bad. Then remove spark plug cover. Remove valve cover. Remove intake from head. remove coil from head. remove heat shield from exhaust manifold then remove manifold from exhaust and from head. remove water hoses and connecting assemblies from side of head and rear of head. remove Cam shaft bearing caps loosening them all evenly so as not to bend cams. remove cams. remove head bolts. remove head. remove valve hydraulic lifters, compress valve springs and remove valve retainers and dissassemble valves. Clean everything very well. Make sure head is not damaged. Remove valve guide seals. install new valve guide seals, new valves. Seat valves with valve grinding compound. clean well. instal valves in reverse order of dissasembly. Before putting head on, make sure number 1 cylinder is at top dead center position. install head using proper torque of 18 ft # in a spiral application rotation from the center outward in a clockwise direction. Then do spiral rotation again tightening bolts each one-quarter turn. Repeat the tightening process two more times only turning the bolts one-quarter turn each time. Use new head bolts. They are designed to stretch in the process of installation and are not to be re-used. Align cams to proper orientation then bolt into place. do not overtorque cam bearing cap bolts. Less than 5 ft # of torque can stretch these bolts. Snug them then tighten them 90 degrees. Then tighten them another 90 degrees (quarter turn). Snug them all then go back and tighten all of them a quater turn, then go back and tighten all of them another quarter turn. Install the cam idler and tensioner and install the cam belt. then install the intake, exhaust and all other items in reverse order of assembly. Do not turn engine over unless you are sure you have the cam belt on with the crank shaft pulley aligned at top dead center and the intake and exhauste pulley marks aligned to their proper marks with the cam belt properly tensioned. You can't be even one tooth off. This must be right before you turn the engine over! Remove spark plugs and turn engine over by hand two rotation clockwise using a wrench on the center bolt of the crank shaft pulley. Check that the timing of cams is still perfect. If not, correct, retension cam belt, double check timing positions again then rotate engine two revolutions. Check cam timing positions again. The timing should not change! The engine should turn over relatively easily. If it feels like it doesn't want to turn, don't force it. You may have the timing off and be pressing a piston against a valve. If you are at this point, then you need to remove cam belt and unbolt cam shafts to release all tension on any of the valves. return the number one cylinder to top dead center position and then reinstall the cams and cam belt. Once it is assembled and in time, then reattatch the rest of the components that were removed in dissassembly. Do this in reverse order of dissassembly. then connect battery and fill radiator fluid. Start car.
