SOURCE: turns over but won't fire

well the plastic piece are from the timing chain guides are either broken or ripped off,and the metal rattling was probably the timing chain,,i think the timing chain jmped or broke and broke the guides,if thats the car you most likely bent the valves in the head,,,i would remove the cam cover and the timing chain cover and see what you got,you may need a engine

SOURCE: does my 2001 saturn sl 1.9l have a timing belt or chain?

It is a chain and its not the easiest but it could be worse.It is as follows:
1.9L SOHC Engine

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Drain the engine oil.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Right front wheel and splash shield
    NOTE: Place a 1 in. x 1 in. x 2 in. long block of wood between the torque strut and cradle to ease removal and installation of the torque engine mount.
    • 3 right side upper engine torque axis to front cover nuts and the 2 mount to midrail bracket nuts, allowing the powertrain to rest on the block of wood
    • Drive belt, tensioner and pulley
    • Power steering pump attaching bolts and set the pump to the side with the lines still attached
    • A/C compressor from the bracket and set aside with the lines attached
    • Camshaft cover
    • Using a strap wrench or a piece of wood wedged between the damper spoke and the lower side of the engine front cover, hold the damper and remove the bolt. With a suitable 3-jaw puller and the slots cast into the damper, pull the crankshaft damper/pulley assembly from the crankshaft.
    • Install the special oil seal replacement tool SA9104E, to be sure the front crankshaft timing sprocket is held firmly in place and prevent guide damage. Install with the flat side towards the crankshaft sprocket.
    • Remove or disconnect the following:
      • Front 4 oil pan bolts and cut the seal away from the front cover
      • Front cover bolts and carefully pry the cover away from the cylinder block at the pry location tabs, which are provided. Remove the cover from under the hood or through the wheel well
      • Front cover oil seal from the cover
      NOTE: During timing chain and sprocket removal, position the crankshaft 90 degrees past Top Dead Center (TDC), to be sure the pistons will not contact the valves upon assembly.
    • Carefully rotate the crankshaft clockwise so the timing mark on the crankshaft sprocket and keyway align with the main bearing cap split line (90 degrees past TDC).
    • Remove or disconnect the following:
      • Timing guides and tensioner
      • Camshaft sprocket bolt, using a 7⁄8 in. (21mm) wrench to hold the camshaft. Then, remove the timing chain and camshaft sprocket
      • Crankshaft sprocket
      To install:
    • Inspect the chain for wear and damage. Check the inside diameter of the chain, it should be no more than 16.77 in. (426mm). Inspect the chain guides for wear or cracks and the timing sprockets for teeth or key wear. Replace components as necessary.
    • Verify that the crankshaft keyway is positioned 90 degrees clockwise past TDC (keyway at 3 o'clock). The keyway should align with the split between the bearing cap and engine block.
    • Bring the camshaft up to No. 1 TDC by loosely installing the sprocket and rotating the sprocket until the timing pin can be inserted. The camshaft contains wrench flats to assist in turning the shaft. The dowel pin should be at 12 o'clock when the camshaft is at TDC.
    • Install the crankshaft sprocket, then rotate the crankshaft counterclockwise 90 degrees up to No. 1 TDC (keyway at 12 o'clock).
    • Position the chain under the crankshaft sprocket and over the camshaft sprocket. The timing chain should be positioned so that 1 silver link plate aligns with the reference mark on the camshaft sprocket and the other aligns with the downward tooth (at the 6 o'clock position) on the crankshaft sprocket. The letters FRT on the camshaft sprocket must face forward, away from the cylinder head and excess chain slack should be located on the tensioner side of the block.
    • Install or connect the following:
      • Timing pin to verify proper alignment of the camshaft and sprocket. Torque the sprocket bolt to 75 ft. lbs. (102 Nm).
      NOTE: Do not allow the camshaft retaining bolt to torque against the timing pin or cylinder head damage will result.
      • Timing chain guides with the words FRONT facing out. Install the fixed guide first and verify the chain is snug against the guide, then install the pivot guide. Torque the bolts to 19 ft. lbs. (26 Nm) and verify that the pivot guide moves freely
      • Retract the tensioner plunger and pin the ratchet lever using a 1⁄8 in. No. 31 drill bit inserted in the alignment hole at the bottom front of the component
      • Tensioner. Torque the bolts to 14 ft. lbs. (19 Nm), then remove the drill bit
    • Make one final check to verify all components are properly timed, then remove all timing pins.
    • Install or connect the following:
      • Seat a new front cover oil seal using the installation tool with a press
      • If the engine front cover casting or assembly is replaced, the 3 torque axis mount studs should also be replaced. Torque the new studs to 19 ft. lbs. (25 Nm).
1.9L (DOHC) Engine
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. drain the engine oil.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Right front wheel and splash shield
    NOTE: Place a 1 x 1 x 2 in. (25 x 25 x 51mm) block of wood between the torque strut and cradle to ease removal and installation of the torque engine mount.
    • 3 right side upper engine torque axis to front cover nuts and the 2 mount to midrail bracket nuts, allowing the powertrain to rest on the block of wood
    • Drive belt, tensioner and pulley
    • Power steering pump attaching bolts and set the pump to the side with the lines still attached
    • A/C compressor from the bracket and set it to the side with the lines attached
    • Camshaft cover
  4. Using a strap wrench or a piece of wood wedged between the damper spoke and the lower side of the engine front cover, hold the damper and remove the bolt. With a suitable 3-jaw puller and the slots cast into the damper, pull the crankshaft damper/pulley assembly from the crankshaft.
  5. Install the special oil seal replacement tool SA9104E or equivalent, to be sure the front crankshaft timing sprocket is held firmly in place and prevent guide damage. Install with the flat side towards the crankshaft sprocket.
  6. Remove or disconnect the following:
    • Front 4 oil pan bolts and cut the seal away from the front cover
    • Front cover bolts and carefully pry the cover away from the cylinder block at the pry location tabs, which are provided. Remove the cover from under the hood or through the wheel well

SOURCE: heavy ticking from top of motor on 1998 sl2.

Check your oil first. I guarantee your car burns oil and it may be very low on low. The ticking may be a lifter starved for oil or one that has debris in or on it. The timing chain usually makes a "slapping" sound when it gets slack in it from lack of tensioner adjustment.

A sure fire way to check the timing chain if you are concerned is to take off the valve cover (also a good time to replace the valve cover gasket). Then you can see the chain and feel and see if there is any slack in it.

First check the spark plugs. (color, burn pattern) next check for spark. Then check compression on all cylinders to see if they are equal.

A timing belt gives no sign, its a scheduled replacement. See if cam is turning while trying to crank engine. If its not, the belt is broken. The engine will usually crank faster than normal because there isnt any compression.

1998 Saturn SL Overheated, then died. very little steam or smoke. No clunk, or grinding noise, but now wont start. Let it cool and filled coolant resevoir it was low. Oddly had to put in 2 qt of oil...


There's a few possibilities of what might have happened. If the motor got hot enough to warp the cylinder head then the head gasket could have failed between two or more cylinders which would allow the engine to crank over quite freely but not start. The 1.9L engine has a timing chain which rarely fails so I doubt if you have any problems there. A compression test and a cooling system pressure check should be done to see where the problem is and what kind of damage has been done. Engines with aluminum heads don't tolerate much overheating and warp quite easily once they reach a certain temp.

An engine needs 3 things to run: Fuel, compression, ignition.

Maybe the timing belt went out. Take off the dist cap and see if the rotor turns as you crank the engine.

Next run a compression test on all the cylinders.
