yet again
no car body stated, an ISUZU WHAT?> is this too much to ask?
no country,
no year stated,
and the poster dont know all books are indexed by...
drum roll, country model, then year., (all 3 missing, is this fun?)
and this engine, is twin cam.. the correct name is
6ve1 99 to 2004? is 3.5L
the early 2 cam is called 6VD1W (w= 4 cams total)
1998 to 2002 on usa spec troopers (guess #2)
the 2 cams in one head are gear driving side by side,
we have posted this answer on this forum over 5 times
search much>?

did i guess right? so now ill post again this data. using online official sources, not rag books.
photos posted yet again, here we go, the hard way, guessing the freakn car,.. wow.
called the VIN V engine. here.USA>







and the words

1. Verify that the sprocket timing marks are still aligned and that the groove and the keyway on the crankshaft timing sprocket align with the mark on the oil pump. The white pointers on the camshaft timing sprockets should align with the dots on the front plate.
2. Install the timing belt. Use clips to secure the belt onto each sprocket until the installation is complete. Align the dotted marks on the timing belt with the timing mark opposite the groove on the crankshaft sprocket. NOTE The arrows on the timing belt must follow the belt's direction of rotation. The manufacturer's trademark on the belt's spine should be readable left-to-right when the belt is installed.
3. Align the white line on the timing belt with the alignment mark on the right bank camshaft timing pulley. Secure the belt with a clip. 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.
4. Rotate the crankshaft counterclockwise to remove the slack between the crankshaft sprocket and the right camshaft timing belt sprocket.
5. Install the belt around the water pump pulley.
6. Install the belt on the idler pulley.
7. Align the white alignment mark on the timing belt with the alignment mark on the left bank camshaft timing belt sprocket.
8. Install the crankshaft pulley and tighten the center bolt by hand. Rotate the crankshaft pulley clockwise to give slack between the crankshaft timing belt pulley and the right bank camshaft timing belt pulley.
9. Insert a 1.4mm piece of wire through the hole in the pusher to hold the rod in. Install the pusher assembly while pushing the tension pulley toward the belt.
10. Pull the pin out from the pusher to release the rod.
11. Remove the clamps from the sprockets. Rotate the crankshaft pulley clockwise 2 turns. Measure the rod protrusion to ensure it is between 0.16-0.24 in. (4-6mm).
12. If the tensioner pulley bracket pivot bolt was removed, tighten it to 31 ft. lbs. (42 Nm).
13. Tighten the pusher bolts to 14 ft. lbs. (19 Nm).
14. Remove the crankshaft pulley. Install the lower and upper timing belt covers and tighten their bolts to 12 ft. lbs. (17 Nm).
15. Fit the oil cooler hose onto the timing cover and tighten its mounting bracket bolts to 16 ft. lbs. (22 Nm).
16. Install the crankshaft pulley and tighten the pulley bolt to 123 ft. lbs. (167 Nm).
17. Install fan pulley assembly and tighten the bolts to 16 ft. lbs. (22 Nm).
18. Install and adjust the accessory drive belts.
19. Install the cooling fan assembly and tighten the bolts to 72 inch lbs. (8 Nm).
20. Install the upper fan shroud.
21. Install the air cleaner assembly and intake air duct.
22. Connect the negative battery cable

and wants head torque too, need egg in your beer?

90 Storm, must be in Canada, 1,6 (the comma tells me this)
the storm is a:
The car is really an Isuzu Impulse minus some of that car's more expensive features.
my guess is you drove the this 4EX1 engine until the cam belt slipped. yes> if yes you bent valves.????????????
so does compression exceed 150psi on all 4 cylinders now?
we use the cylinder leak down test in all DOHC .
if not , back to the drawing board.
if yes, the we check spark next, then try test fuel.
when did the engine last run , last week,month , year,?
who did your valves, a real machine shop or kid down the street.
a read shop pressure tests the head ,and warp checks it and
then makes sure the valves are ready for long service.
are the head bolts at 58 ft/lbs
did you use sealant on the 3 cap caps, per the FSM book.
if not , top end oiling will fail. and cams wrecked.

the 1.6l DOHC has no HLA's
the lash on valves must be checked, and this is corrected with SHIMS.

a pro machine shop does the for you,did they:?
when rebuilding engines, its best to read the factory service manual first. FSM so you know the special steps just for this engine.
ISUZU engine it is.

1.6L Twin Camshaft Engine

1. Disconnect the negative battery cable.
2. Remove the cylinder head or valve cover.
3. Position the No. 1 cylinder at TDC on its compression stroke.

The notch on the crankshaft pulley should align with the 0 degrees mark on the timing gear case. Make sure the rocker arms on the No. 1 cylinder are loose and the rockers on the No. 4 cylinder are tight. If not, turn the crankshaft one complete revolution and align the marks again.

1. Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 1 cylinder, then the intake valves on the No. 2 cylinder and the exhaust valves on the No. 3 cylinder. Note readings.
2. Rotate the crankshaft 360 degrees. Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 4 cylinder, then the intake valves on the No. 3 cylinder and the exhaust valves on the No. 2 cylinder. Note readings.
3. The valve clearance obtained on the exhaust valves should be between 0.008-0.012 in. (0.20-0.30mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 (valve lash spring spacer) between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.

The rear camshaft bearing caps must be removed to remove the selective shim.

1. The valve clearance obtained on the intake valves should be between 0.004-0.008 in. (0.10-0.20mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.
2. When the adjustment is completed, install the cylinder head covers and connect the battery negative cable. Start the engine and check for leaks.

see those 2 marks, and crank must be at TDC. mark first.

the timming gear that the belt runs on has a mark (V cut in gear) to rear cover at about 12 o clock and crank pulley has timming mark for top dead centre, both cams have cut outs in rear that a special tool (camshaft stopper 5-8840-2592-0) locks into to hold cams in correct position, but can do without this, if the cam belt gear is off, the keyway should be at 12 o clock. the marks in the camshaft gears (dots) is for assembly of sissor gears to solid gears on camshafts that run together and they should match up only if you had this appart.

no.1 is timming mark

this is the locking plate tool

4 Cylinder diesel(4JX1) :
1 - Timing mark
2 - Cam pulley
3 - HP Oil pump pulley
4 - Tensioner pulley




6 Cylinder petrol:
Align crank(C) timing notch mark (1) to oil pump mark.
Align cam pulley(L+R) marks(3) to cylinder head marks
The cam belt has 3 marks, 2 lines and one mark that is actually a row of dots. Align the dots to the crank pulley groove mark(2) and align the other 2 lines to the cam pulley marks. Using a clothes peg to hold the belt to the cam pulleys works wonders to keep it in place while fitting. Please note the arrows on the belt and have them point in the direction of rotation - right to left side of engine
W - water pump pulley
I - Idler pulley
T - Tensioner pulley.

If for some reason you need to realign the cams on each bank :
Standing in front of the car and starting from YOUR left , looking at the cams you should see RE, RI, LI, LE on each of the camshafts.(R for right bank, L for left bank, I for intake and E for exhaust) Right bank camshafts are marked with one dot, left bank with 2 dots on the shaft itself. To align the camshafts to each other each cam shaft gear has a mark on it. Draw an imaginary line between the centre of the camshaft and the centre of the pulley. The alignment mark should be between the two along this imaginary line. The result will be that RI an RE will be at the top of each gear. The same with the left bank.

8. Align the single timing mark on the right exhaust camshaft sprocket with the notch on the timing belt cover.
9. When the single timing mark on the right exhaust camshaft sprocket is aligned with the notch on the timing belt cover, ensure that the double lines on the intake camshaft and exhaust camshaft sprockets are aligned.
10. Align the single timing mark on the left exhaust camshaft sprocket with the notch on the timing belt cover by turning the sprocket counter clockwise (viewed from front of engine).
11. Ensure that the double lines on the intake camshaft and exhaust camshaft sprockets are aligned when the single timing mark on the left exhaust camshaft sprocket is aligned with the notch on the timing belt cover. CAUTION
    • The camshafts can be rotated independently causing the valves heads to contact each other resulting in bent valve stems.
    • When the timing belt is removed the camshafts will turn to the lowest cam lobe position by the force of the valve springs. Before installing the timing belt the 4 camshafts are in the lowest lift position (valves closed).
    • When the camshafts are rotated to install the timing belts, # 2 intake and # 4 exhaust cam lobes of the left camshafts are held to push their corresponding valves down. In this position, these valves are held in the open position. Right camshafts are held so their cam lobes do not push the valves down.
    • The left camshafts must be rotated from the lowest lobe position to the position where the timing belt can be installed at the smallest possible angle in order to prevent intake and exhaust valve contact. Camshaft sprockets rotation
      
      
    • Do not turn the camshafts in the direction shown in the illustration because the valves will open at the same time and contact each other.
    CAUTION
    If the timing belt alignment is off the mark buy more than 3 teeth, the valves and pistons may have contact.
    Timing belt alignment marks DOHC
    
    
12. Align the timing marks on the belt with the marks on the sprockets in the numerical order shown in the illustration.

Aah I see. Let's start from the beginning then. Standing in front of the car and starting from YOUR left , looking at the cams you should see RE, RI, LI, LE on each of the camshafts.(R for right bank, L for left bank, I for intake and E for exhaust) Right bank camshafts are marked with one dot, left bank with 2 dots on the shaft itself. To align the camshafts to each other each cam shaft gear has a mark on it. Draw an imaginary line between the centre of the camshaft and the centre of the pulley. The alignment mark should be between the two along this imaginary line. The result will be that RI an RE will be at the top of each gear. The same with the left bank. Also read this: http://www.fixya.com/cars/t3609098-nned_know_set_cam_engine_timing
It explains setting the timing further. Get these set up correctly and then we can dig further. I can post a diagram but haven't figured out how on Fixya yet.

if this is 6VD1 engine it has single cam gear each head, but is still a 2 cams per head, engine
if belt has broke or you have turned any gear you must remove rocker covers to check positions of camshafts front lobes are in certain spot as well as timming mark on belt driven cam gear to cover
this cam gear is a 3:1 ratio (3 turns of cam gear = 1 turn of cams)
