The intake cam will be at 11 o'clock and the exhaust cam will be at 2:30. There are 12 links between the indicators not counting the indicator links.

I need the timing marks for 2006 Nissan Altima Sl


There should be timing marks on the cam gears which, with a new chain from Nissan, will line up with specially colored links in the timing chain at Top Dead Center. This forum post goes into a bit more detail: Timing marks on the cam chain

How many chain link do I count to set the timing


When you are setting timing you are setting top dead center and bottom dead center. Once established based on the marks on the crank and cam you adjust top dead and BDC by degrees in ADVANCED timing or behind/retarded timing by degrees by counting links. Each link used to be 5 degrees. Check repair manual on link values! they change with each engine and maker.

How do i set timing chain on sprockets ,ie top dead centre.


I don't know what car you have, so here's what was needed on mine:
1. Bring engine to Top Dead Center, ready to fire #1. There should be a mark on the front pulley or on the flywheel. Move cams to the TDC mark, too. My car was twin cam, the front cams needed to face apart, and set the marks....

Yours may be different.

Instruction changing timing belt 1979 Alfa Romeo Spider Veloz?


With Cam Caps loosened, FIRST loosen timing chain tensioner, press it in to loosen tension, Crank using ratchet to TDC (Top Dead Center on crank pully, (to keep from damage to pistons), align Exhaust Cam Timing Mark to mark on #1 Exhaust cam cover, then take up slack between Exhaust & Intake Cams (on top between the cams), Then align the Intake Cam to mark on #1 Cam Cap, "Now" loosen the 17mm bolt to tighten timing chain, rotate engine using rachet two times, reset TDC at the crank, and look at "Cam Timing Marks on both the Exhaust, and Intake Cams. If you did all this correctly the "Timing Marks" should be lined up so TDC,Exhaust, and Intake marks are all the same.

I took old timing chain off my 2001 Mercury Marquis 4.6 and something moved, either one of the cam gears or both. I set the timing on the crank shaft to top dead center, but now I can't get the m


what you have to do is clean the chain very well you are looking for 2 links that are different colors than the rest (bronze colored ) count the links between the two rotate the cam 2 12:00 with the dowel pin up or the dot on the edge of the pulley put the chain on with the links on each mark and set the tensioners in place

    NOTE The timing chain has 2 matching colored links and 1 uniquely colored link.
    Negative battery cable, PCV hose, Fuel line bracket, Ignition coil and module assembly Ground strap from camshaft cover, Camshaft cover, Front fender liner, Accessory drive belt Crankshaft balancer pulley, Accessory drive belt tensioner, Front cover-to-water pump bolt Remaining front cover bolts, Front cover
  5. Rotate the engine until the crankshaft sprocket mark aligns with the matching colored link (2) at the 5 o-clock position.
  6. Confirm that the INT diamond on the intake camshaft sprocket is aligned with the uniquely colored link at (1) the 2 o-clock position.
  7. Confirm that the EXH triangle on the exhaust camshaft sprocket is aligned with the matching colored link (3).
  8. Remove or disconnect the following:
    NOTE Use a 24 mm wrench to hold the camshafts to prevent them from turning.
    Timing chain tensioner, Fixed timing chain guide access plug, Fixed timing chain guide Upper timing chain guide, Exhaust camshaft sprocket, Timing chain tensioner guide Intake camshaft sprocket, Timing chain through the top of the cylinder head Crankshaft sprocket

    Fig. Aligning the exhaust camshaft sprocket (3).

To install:
  1. Install the crankshaft sprocket with the timing mark in the 5 o-clock position.
  2. Assemble the intake camshaft sprocket to the timing chain with the timing mark lined up with the uniquely colored link (1). Hand tighten a new intake camshaft sprocket bolt.
  3. Lower the timing chain through the opening in the cylinder head.
  4. Route the timing chain around the crankshaft sprocket and line up the first marching colored link (2) with the timing mark on the crankshaft sprocket.
  5. Install the exhaust camshaft sprocket with a new bolt loosely onto the exhaust camshaft.
  6. Align the timing mark on the sprocket with the last matching colored (3).
  7. If necessary, align the camshaft as follows:
    1. Using a 24 mm wrench, first turn the intake camshaft until the alignment feature on the back of the camshaft sprocket seats in the notch in the front of the intake camshaft.
    2. Turn the crankshaft 45 degrees in either direction.
    3. Turn the intake camshaft to the appropriate location.
    4. Turn the crankshaft back to top dead center (TDC).
  8. When the sprocket seats in on the camshaft, tighten the sprocket bolt hand tight.
  9. Verify all of the colored links and the appropriate timing marks are still aligned.
  10. Install the fixed timing chain guide. Tighten the bolts to 133 inch lbs. (15 Nm).
  11. Install the upper timing chain guide. Tighten the bolts to 89 inch lbs. (10 Nm).
  12. Using a 24 mm wrench to hold the camshafts, tighten the camshaft sprocket bolts 63 ft. lbs. (85 Nm) plus 30 degrees.
  13. Measure the timing chain tensioner from end to end. A new tensioner should be supplied in the fully compressed non-active state. A tensioner in the compressed state will measure 2.83 inches (72 mm) front end to end. A tensioner in the active state will measure 3.35 inches (85 mm) from end to end.
  14. If the timing chain tensioner is not in the compressed state, perform the following steps:
    1. Remove the piston assembly from the body of the timing chain tensioner by pulling it out.
    2. Install the bottom half of the Tensioner tool J-45027-2 into a vise.
    3. Install the notch end of the piston assembly into the bottom half of the tensioner tool.
    4. Using the top half of the Tensioner tool J-45027-1, turn the ratchet cylinder into the piston.
    5. Install the compressed piston assembly back into the timing chain tensioner body until it stops at the bottom of the bore. Do not compress the piston assembly against the bottom of the bore.

  15. Install the timing chain tensioner assembly. Tighten to 66 ft. lbs. (75 Nm).
  16. Release the timing chain tensioner by compressing it approximately 0.08 inches (2mm). Feed a rubber-tipped tool down through the cam drive chest to reset on the cam chain. Give the tool a sharp jolt diagonally downwards to release the tensioner.
  17. Install the timing chain oiling nozzle.
  18. Install the timing chain guide bolt access hold plug with silicone sealant on the threads. Tighten the plug to 59 ft. lbs. (90 Nm).
  19. Install or connect the following:

    Camshaft cover. Tighten the bolts to 89 inch lbs. (10 Nm). Front cover with new gasket. Tighten the bolts to 18 ft. lbs. (25 Nm). Accessory drive belt tensioner. Tighten the bolts to 33 ft. lbs. (45 Nm). Crankshaft balancer pulley using a new bolt. Tighten the bolt to 74 ft. lbs. (100 Nm) plus 75 degrees. Accessory drive belt, Front fender liner, Ground strap to camshaft cover Ignition coil and module assembly, Fuel line bracket, Air intake assembly, Negative battery cable
  20. Refill the cooling system to the correct level.

I have 2003 chevy impala (V6 3.4 liter) i recently replaced both head gaskets. The car was running fine and now with engine back together engine want turn over sounds like its not firing but the plugs...


Did you get the timing set correctly when you reattached the cam to the timing chain? It sounds like you didn't have the #1 Top dead center or the cams were in the wrong position when you reset the timing chain. The cam shaft and Crank will actually look like they are set correctly two times. Once when it is in time and once when it is out of time 180 degrees. If you are more than 5 degree out of time or more than 5 degrees from the point where it is 180 degrees out of time the engine normally won't fire at all. The easiest way to check and verify this is to do compression checks on the cylinders, you will find you have little or no compression on several cylinders if this is the case. To correct it remove the timing chain and set the crank to #1 Top Dead center. Then go to the head that is on the #1 side, line the cam up so that both valves are closed for the number 1 and line that mark up. You have to find the firing order to make sure the intake is open getting ready to close for the next cylinder that going to fire and the exhaust valve is closed, then make teh final adjustment to line that cams timing mark up then replace the timing chain. This should get everything roughly within 5 degrees of zero and should get the motor so it will start.

Set timing after rebuild


make sure #1 is top dead center(TDC) or all the way up in the bore. Set the lower chain, use the marks dot to dot. then the cams, the intake cam has it's own mark as well as the exaust cam the marks on the cam should be strait up and down to the reflecting cam. put the chains on. Spin the engine over by hand to make sure you are right.
