Help me to remove my cylinder head of my mazda 2005 drifter b250


  • Hi Ronald, Get ready for a lot of work! The first thing is to clean the engine of all dirt and contaminants that may cause damage when the head id removed. When the engine is cold disconnect the battery. Remove the air cleaner ducting and housing and then drain the coolant from the radiator and engine block. The coolant drain plug on the engine block sometimes becomes corroded so be careful and if it is too tight leave it. Get yourself some masking tape and mark all the relevant electrical connections before removing them. If your engine is the type with timing gears turn it to Top Dead Center (TDC) and once set leave it. If it has a timing belt remove the front plastic timing cover and look for and identify the match marks for valve timing. If you can't see them make your own marking the TDC positions of the camshaft in relation to the cylinder head, (This may save you a lot of pain and suffering later) If the engine is diesel, identify or match mark the timing gear in relation to Crank Shaft and Cam Shaft. Remember the body of the injector pump when turned is also an adjustment so match mark the pump body to the engine. With a diesel, mark the pipes and make a sketch of where each pipe fits onto the distributor type pump. (Do not bend the pipes) If it's a petrol engine mark the position of each of the HT plug leads, remove the distributor cap and sketch the position of the rotor arm in relation to the cap. (In other words note which way it's facing. Remove the cap and the plug leads. mark all vacuum tubes for later reinstatement before disconnecting. Disconnect all electrical connections (Which you should have marked) Remove the tappet cover and clean the oil, which should be correctly taken care of. If the engine has a timing belt, loosen the tensioner bearing to its maximum adjustment and making sure that the timing marks are still aligned remove the belt. If it has a belt it will usually have overhead cam. If gears it will likely have a rocker shaft assembly and push rod operated valves. Begin to loosen these from the front and back working in to the center of the head. Loosen each bolt evenly, one turn at a time until the whole cam or rocker assembly is loose and can be removed. Keep in mind that up until this point certain valves will be open and under tension Once removed the the valves will then be fully closed. Remove the intake and exhaust manifolds, alternately loosening from each end working towards the center. Remove the radiator cooling hoses and ensure that bypass hoses are removed too. Make sketches of the fitting positions before removal. Closely inspect all areas where bolts and brackets may impede the removal, and if any remain, remove them. Careful inspection and recording will help you greatly during assembly. You are now ready to remove the cylinder head. Begin at the front of the engine by loosening the first bolt of the cylinder head and then go to the rear and loosen the bolt diagonally opposite. Follow the same loosening sequence working towards the center until all bolts are loosened. and then remove them. The cylinder head can now be removed. In the case of the engine being diesel powered, look at the outer edge of the gasket where you should see an indicator of the gasket thickness. This is very important when buying the replacement gasket (never reuse an old gasket) The thickness is in relation to the piston protrusion above the engine block and if the replacement is too thin, the valves will collide with the pistons during operation (which ain't very good for pistons or valves!) If the gasket is too thick the compression will not be achieved for maximum performance. I suggest that when the head is removed, after cleaning it should be taken to an engineering company for checking and if warped it should be lightly skimmed. The tightening sequence is opposite to removal, meaning begin at the center and work outwards. This applies to the cylinder head, manifolds and tappet cover. In fact not a bad idea for everything you apply a spanner or wrench to. Ps. Why do you want to take the head off? Just asking. Regards John

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.

Can u help me with a timing setting on my 97 toyota camary le 2.2ll or some kind of mark to guide me on?


Hi,
Are you looking for ignition timing or valve timing marks?
The ignition timing is set at 10 degrees BTC. the marks are at the front of the engine and the degrees are scaled onto a raised molding on the plastic timing belt cover. There is a line marked on the pulley. Paint with correcting fluid the 10 degree mark and the pulley mark. Correct timing is 10 degrees BTC.
Before setting, open the diagnostic connector in the engine compartment and using a short piece of electrical wire and bridge between "T" and 'E' If this is not done the timing will not be corrected.
If you've replaced the timing belt and you're looking for the timing marks, the mark for the crank shaft is a raised casting forming a small pointer for the crank shaft which aligns with a groove in the crank timing gear....When looking from above at the relevant section of the engine, it will appear on your right hand side just above the crankshaft timing gear.
The marks for the cams are holes drilled through each and these should be aligned with punch marks on the cylinder head. The best way of doing this job is by using a mirror and illuminating between the cam gears and the cylinder head.
Hope this helps

  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.
