Hi there's this website something like reliable-store and it is very amazing for manual for repairing servicing anything
someone on fixya recommended it to me and I thank him even today
They have full manuals and it's verrrrry che ap and mine
I got free in offers
3rd time I also had an issue with
the file so the girl replaced it in 30 mins
there is one more but i don't remember its name it was 2 years back bitman something link this
Try it out brother

If the Pontiac engine is similar to the small block Chevy, you have, I believe, a hexagonal shaft that runs from the end of the distributor shaft down to the oil pump. This is turned when the distributor shaft is turned by the meshing gears on the camshaft and distributor shaft. I would say that you are probably going to have to re-time the engine. Find TDC, then replace the distributor. It won't matter a whit to the oil pump if the gears are one or two teeth off, but it will matter a great deal if you distributor is not installed so it can be adjusted a few degrees when you get to "fine timing" the engine.

You should be able to download information on how to time the engine (finding TDC, etc.). Failing that, a trip to the library may be in order.

Put the Crankshaft to TDC, then roll it back a quarter turn to allow the Camshaft to be rotated into the proper position. Once the camshaft is correct, roll the crankshaft back to TDC and install belt. Having your crank at TDC will not allow your valves to open and close (interference engine).

see diagrams from autozone.com. Cam sprocket has an "UP" label, but also 2 scribes on the sides to align to upper head surface. The critical part of the job is keeping tension on the side of the belt that is opposite from the tensioner as the tensioner is released onto the belt. The timing marks must be aligned when the job is done.


To install:

1. Install the camshaft timing sprocket so that the UP mark is up and the TDC marks are parallel to the cylinder head gasket surface. Install the key and tighten the bolt to 27 ft. lbs. (37 Nm).
2. Install the crankshaft sprocket so that the TDC mark aligns with the pointer on the oil pump. Install the spacers with their concave surfaces facing in. Install the key. If equipped, install the TDC sensor assembly back into position before installing the timing belt.
3. Install and tension the timing belt. Use a 6 x 1.0 mm x 25 mm bolt threaded through the cam belt tensioner plate to temporarily hold the tensioner.
4. Temporarily install the crankshaft pulley and rotate the crankshaft counterclockwise 5-6 turns to be sure the belt is properly seated.
5. Set the No. 1 piston at TDC for its compression stroke.

WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.

1. Rotate the crankshaft counterclockwise so that the camshaft pulley moves only 3 teeth beyond its TDC mark.
2. Loosen, then retighten the temporary cam belt tensioner bolt.
3. If the rear balance shaft sprocket/gear case assembly was removed, perform the following:
   1. If the rear balance shaft was moved, rotate the balance shaft until the 6 x 1.0mm x 100 mm bolt can be installed into the maintenance hole to the scribed line.
   2. Align the notch of the balance shaft sprocket edge with the pointer on the gear case. Install the rear balance shaft sprocket/gear case assembly using a new O-ring coated with fresh engine oil. The balance shaft sprocket should be installed in the TDC position. The pointer on the gear should align with the pointer on the oil pump housing plate.
   3. Tighten the mounting bolts to 18 ft. lbs. (25 Nm).
   
   
4. If the front balance shaft sprocket was removed, perform the following:
   1. Install a suitable and sturdy screw driver or drift through the maintenance hole in the shaft behind the sprocket to hold the front balance shaft.
   2. Install the front balance shaft sprocket and mounting nut. Torque the nut to 22 ft. lbs. (29 Nm).
   
   
5. Make sure the balance shafts and crankshaft are in the TDC position.
6. Remove the crankshaft pulley, and if removed, install the balance shaft belt drive sprocket.
7. Install the balance shaft belt, making sure the balance shafts and sprockets are still in the TDC position.
8. If removed, install the balance shaft belt tensioner and tension the balance shaft belt.
9. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
10. Remove the 6 x 1.0mm x 100mm rear balance shaft holding bolt.
11. Temporarily install the crankshaft pulley and rotate the crankshaft 2 revolutions counterclockwise, stopping at TDC.

WARNING If any resistance is felt, stop immediately and determine the cause.

1. Recheck that all of the TDC marks align for both the camshaft and balance shafts.
2. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
3. Remove the 6 x 1.0 mm x 25 mm bolt used to secure the camshaft timing belt tensioner.
4. Remove the crankshaft pulley and install the lower cover.
5. Install the crankshaft pulley, lubricate the bolt threads and both sides of the crankshaft pulley bolt with fresh engine oil and tighten the crankshaft pulley bolt to 181 ft. lbs. (245 Nm). Do Not use an impact wrench.

See Figures 19 and 20

1. Install the upper timing cover and the valve cover. Be sure the seals are properly seated.
2. Install the side engine mount. Tighten the through-bolt to 47 ft. lbs. (64 Nm). Tighten the mount nut and bolt to 40 ft. lbs. (55 Nm) each.
3. Remove the floor jack.
4. Install and tension the alternator belt.
5. Install the power steering pump and tension its belt.
6. Install the splash shields.
7. Reconnect the positive and negative battery cables. Enter the radio security code.
8. Check engine operation.

One is on the crank shaft pully (for TDC). It is a line, scribed on the pully, that alligns to a pointer on the plastic timing belt cover. The second is on the cam shaft pully. It can be accessed by removing the rubber inspection plug on the timing belt cover. The third is on the auxillary shaft (oil pump) and is also accessed through an inspection plug on the timing belt cover.

On the cam and oil pump pullies, the diamond aligns to the diamond and the triangle aligns to the triangle (the pullies have both). These should be perfectly aligned when the crankshaft pully line is at 0 deg TDC. If you can't see the marks through the inspection port while the crank is at 0 TDC, you are 180 degrees out - turn the crank one more time. 

the crank has a mark for TDC. (white) and the cam gear should have UP marked on it. You want the UP mark UP at the 12 oclock position.(as you are looking at the top pulley) there will be marks at the 3 and 9 oclock positions and these marks line up the the flat portion of the head that the valve cover sits on. While its apart ......replace the timing belt, and replace the pulley, and replace the cam and crank shaft seals, adjust the valves.

Hi,

If your turbo housing is getting flooded with oil the it can only come from the shaft seal on the inside of the turbo.

You will need to remove it and replace the shaft seal.

If the engine is cranked (disturbed) with the distributor removed, it will now be necessary to retime the engine.

1. Rotate the engine so that No.1 piston is at TDC of the compression stroke.
   
2. Align the timing marks to the correct ignition timing shown on the underhood decal.
   
3. Install the distributor with the rotor in the No.1 firing position and any armature pole aligned with a stator pole.
   

Make sure that the oil pump intermediate shaft properly engages the distributor shaft. It may be necessary to rotate the engine after the distributor gear is partially engaged in order to engage the oil pump intermediate shaft and fully seat the distributor in the block.

1. If it was necessary to rotate the engine to align the oil pump, repeat Steps 1, 2 and 3.
   
2. Install the holddown bolt finger tight.
   
3. Install the distributor cap and wires.
   
4. Connect the distributor wring connector to the wiring harness. Tighten the holddown bolt.
   
5. Install the air cleaner, if removed.
   
6. Check the ignition timing as outlined in Section 2.
   
7. When everything is set, tighten the holddown bolt to 25 ft. lbs.
   

You must find the cam lock bar and crank lock pin to do this job properly, otherwise you can bend some valves and that becomes expensive..the front crank damper has a mark to line up with a mark on the timing cover for #1 TDC, but the cam lock bar is what aligns the cams into position. The crank lock pin is helpful but not 100% necessary...
