"Ignition timing is controlled by the Powertrain Control Module (PCM). No adjustment is possible"
so Cam timing (alldata.com covers this in detail)
why not post the context, Im doing what.?
im doing a 60k belt swap
or it slipped. or think id did.
or just put in a new head or cam? see , context is 100% important.
im here, going to there.....
im on line, and it shows 4 engines, i think that is wrong, but...

you must be asking chain cam sprocket timing.
im at alldata.com (or FSM)
there are 37 install steps, im not sure what step you want me
to pluck out. but here is my guess. step 8 ,9,10

1. Install both secondary chains onto the idler sprocket. Align two plated links on the secondary chains to be visible through the two lower openings on the idler sprocket (4 o'clock and 8 o'clock).

3. Align the primary chain single plated link with the timing mark at 6 o'clock on the crankshaft sprocket.

step 12:
Install all chains, crankshaft sprocket, and idler sprocket as an assembly . After guiding both secondary chains through the block and cylinder head openings, affix chains with a elastic strap or equivalent. This will maintain tension on chains to aid in installation. Align the timing mark on the idler sprocket gear to the timing mark on the counterbalance shaft drive gear, then seat idler sprocket fully . Before installing idler sprocket bolt, lubricate washer with oil, and tighten idler sprocket assembly retaining bolt to 25 ft. lbs. (34 Nm).

step 13:

1. Align left camshaft sprocket "L" dot to plated link on chain.
2. Align right camshaft sprocket "R" dot to plated link on chain.

step 15/16

REMOVAL & INSTALLATION1.8L Engine
See Figures 1, 2 and 3

1. If possible, position the engine so the No. 1 piston is at TDC.
2. Disconnect the negative battery cable.
3. Remove the timing belt covers.
4. Remove the timing (outer) belt tensioner and remove the outer timing belt.
5. Remove the outer crankshaft sprocket and flange.
6. Remove the silent shaft (inner) belt tensioner and remove the belt.

Fig. 1: Silent shaft belt timing marks-1.8L engine



Fig. 2: Checking the silent shafts for proper positioning



Fig. 3: Timing belt timing mark alignment-1.8L engine

To install:

1. Align the timing marks of the silent shaft sprockets and the crankshaft sprocket with the timing marks on the front case. Wrap the timing belt around the sprockets so there is no slack in the upper span of the belt and the timing marks are still aligned.
2. Install the tensioner pulley and move the pulley by hand so the long side of the belt deflects about 1 / 4 in.
3. Hold the pulley tightly so the pulley cannot rotate when the bolt is tigthened. Tighten the bolt to 15 ft. lbs. (20 Nm) and recheck the deflection amount.
4. Install the timing belt tensioner fully toward the water pump and tighten the bolts. Place the upper end of the spring against the water pump body.
5. Align the timing marks of the camshaft, crankshaft and oil pump sprockets with their corresponding marks on the front case or rear cover.

There is a possibility to align all timing marks and have the oil pump sprocket and silent shaft out of time, causing an engine vibration during operation. If the following step is not followed exactly, there is a 50 percent chance that the silent shaft alignment will be 180 degrees off.

1. Before installing the timing belt, ensure that the left side (rear) silent shaft (oil pump sprocket) is in the correct position as follows:
   1. Remove the plug from the rear side of the block and insert a tool with shaft diameter of 0.31 in. (8mm) into the hole.
   2. With the timing marks still aligned, the shaft of the tool must be able to go in at least 2 1/2 in. If the tool can only go in about 1 in., the shaft is not in the correct orientation and will cause a vibration during engine operation. Remove the tool from the hole and turn the oil pump sprocket 1 complete revolution. Realign the timing marks and insert the tool. The shaft of the tool must go in at least 2 1/3 in.
   3. Recheck and realign the timing mark.
   4. Leave the tool in place to hold the silent shaft while continuing.
2. Install the belt to the crankshaft sprocket, oil pump sprocket, then camshaft sprocket, in that order. While doing so, make sure there is no slack between the sprocket except where the tensioner is installed.
3. Recheck the timing marks' alignment. If all are aligned, loosen the tensioner mounting bolt and allow the tensioner to apply tension to the belt.
4. Remove the tool that is holding the silent shaft and rotate the crankshaft a distance equal to 2 teeth on the camshaft sprocket. This will allow the tensioner to automatically apply the proper tension on the belt. Do not manually overtigthen the belt or it will howl.
5. Tigthen the lower mounting bolt first, then the upper spacer bolt.
6. To verify correct belt tension, check that the deflection at the longest span of the belt is about 1 / 2 in.
7. Install the timing belt covers and all related items.
8. Connect the negative battery cable.

2.0L Engine
1990-94 VEHICLES
See Figures 4, 5, 6 and 7

1. Disconnect the negative battery cable.
2. Remove the timing belt upper and lower covers.
3. Rotate the crankshaft clockwise and align the timing marks so No. 1 piston will be at TDC of the compression stroke. At this time the timing marks on the camshaft sprocket and the upper surface of the cylinder head should coincide, and the dowel pin of the camshaft sprocket should be at the upper side.

Always rotate the crankshaft in a clockwise direction. Make a mark on the back of the timing belt indicating the direction of rotation so it may be reassembled in the same direction if it is to be reused.

1. Remove the auto tensioner and remove the outermost timing belt.

Fig. 4: Exploded view of the timing belt and sprockets-1990-94 2.0L engines

1. Remove the timing belt tensioner pulley, tensioner arm, idler pulley, oil pump sprocket, special washer, flange and spacer.
2. Remove the silent shaft (inner) belt tensioner and remove the belt.
3. Remove the crankshaft retaining bolts, then remove the pulley.
4. Remove the crankshaft sprocket retainer bolt and washer from the sprocket, if used, and remove the sprocket. If the sprocket is hard to removed, the proper puller may be used. If no bolts are used on the sprocket. Use the correct puller to remove.
5. Hold the camshaft stationary using the hexagon cast between journals No. 2 and 3 and remove the retainer bolt. Remove the sprocket from the camshaft.

To install:

1. Install the sprockets to their appropriate shafts. Install the retainer bolts and tighten the camshaft sprocket bolt to 65 ft. lbs. (90 Nm).
2. Check both tensioner and idler pulley for bearing wear, and replace if needed.
3. Align the timing marks on the crankshaft sprocket and the silent shaft sprocket. Fit the inner timing belt over the crankshaft and silent shaft sprocket. Ensure that there is no slack in the belt.

Fig. 5: Align the camshaft sprocket so marks face each other and are in alignment with the top surface of the cylinder head-1990-94 2.0L engine



Fig. 6: Align the crankshaft timing mark and the oil pump sprocket timing mark-1990-94 2.0L engine



Fig. 7: Timing marks in alignment-1990-94 2.0L engine

1. While holding the inner timing belt tensioner with your fingers, adjust the timing belt tension by applying a force towards the center of the belt, until the tension side of the belt is taut. Tighten the tensioner bolt.

When tightening the bolt of the tensioner, ensure that the tensioner pulley shaft does not rotate with the bolt. Allowing it to rotate with the bolt can cause excessive tension on the belt.

1. Check belt for proper tension by depressing the belt on its' long side with your finger and noting the belt deflection. The desired reading is 0.20-0.28 in. (5-7mm). If tension is not correct, readjust and check belt deflection.
2. Install the flange, crankshaft and washer to the crankshaft. The flange on the crankshaft sprocket must be installed towards the inner timing belt sprocket. Tighten bolt to 80-94 ft. lbs. (110-130 Nm).
3. To install the oil pump sprocket, insert a Phillips screwdriver with a shaft 0.31 in. (8mm) in diameter into the plug hole in the left side of the cylinder block to hold the left silent shaft. Tighten the nut to 36-43 ft. lbs. (50-60 Nm).
