SOURCE: where is the rotory button

When #1 piston is up the rotor can be pointing to 2 different places. For every 1 turn on the crankshaft the camshaft turns 2 times. To be sure that the rotor is in the right position to fire #1 spark plug you need to remove the valve cover and watch the valves as you turn the engine. To be correctly positioned the intake valves have to be open and stasrting to close as you turn the crank to align the timing marks (TDC). As you pass TDC the intake valves are closed and the exhaust valves start to open. Back up so the timing marks line up and this is where the rotor is going to fire #1. If this is not what you are seeing, then simply rotate the engine 1 complete turn and you should see it happen then.

Unless you have changed the timing chain or removed the distributor this shouldn't be necessary.Perhaps if you suspect the truck has "jumped her time" then this could help to confirm. If you are doing routine maintenance, plugs, wires, cap and rotor then you don't need to be concerned that the timing marks line up but not the rotor button. Hope this helps.

SOURCE: I have a 2001 Isuzu Vehicross 3.5 engine. Which piston do I set the timing on of which must be at TDC? Is it the number one piston or number two piston?

number 1 piston should be at top dead center. remove the number 1 plug and insert a straw, or a soft object in hole on top of piston. this way when it is all the way up and just before it starts to go down you will know. if it has a dist. make sure rotor button is facing number 1 plug wire. good-day !

Pull #1 spark plug and rotate the engine until you hear air rush out of the cylinder, (plug the hole with your finger if you can), then look at the timing mark, it will be close to TDC

SOURCE: daewoo leganza 2000 2.2 liter if all the timing

It should be top dead center on a compression stroke and all the valve are closed. Both cams have a line the lines up with marks on the valve cover. Basicly the marks on the cams both are set to point to twelve o'clock. The mark on the crank shaft pully points to 6 o'clock or strait down

Good Day. How do I set the valves gap for a Isuzu 161Z motor, is it on rocking stage or completely loose??


completely loose -- piston on tdc compression stroke
if you know the firing order of the engine if no 1 piston is on compression stroke , the next piston to fire will be on valve overlap or valve rock
when it is in the valve rocking situation then no 1 piston will be at maximum clearance for adjustment purposes
repeat the process for the next piston to fire
for example "- 6 cylinder
firing order -- 1-5-3-6-2-4
with no 1 on compression , no 5 valves will be rocking, no 5 on compression no 3 valves will be rocking with no 3 on compression no 6 valves will be rocking and so on

Firing order on a 97 Toyota Tacoma 2.7 liter 4 cylinder


The firing order of in-line 4 cylinder engines is the same (for old car models) of Chevy, Olds, Pontiac, Dodge/Plymouth, Datsun/Nissan, Honda, International, Isuzu/LUV, Jeep, Mazda/Courier, Mitsubishi, Opel, Toyota and VW.
"Always check the exact firing order of your engine. It is is generally stamped or cast on the engine's intake manifold, valve cover or cylinder head."

How to adjust valve lash on a 1990 Geo Storm


its an Isuzu engine.
there are 3 engines.
4XE1, SOHC 1.6L (base)12valves
4XE1, DOHC , 1.6L same as above but now with 16valves.
4XE1, DOHC, 1.8L bends valves if belt snaps...
note the bad idea of ISUZU calling all 3 engine same name.
a horrid idea.
which one? the second was in USA and Canada only.
the second one was offered as the GSI. is yours that?

so I will attempt to guess for you, its the base engine.
(odds of coin toss)
toss #2, USA, SOHC
guess 3: did a new belt and want to do lash next. Cam belt>
No job stated so i guess 3 times.
Just lash.
SOHC 1.6L only (FSM book quote)
Check the valve lash between the rocker arm and valve stem on both the intake and exhaust valves on the number 1 cylinder, the intake valve(s) on the number 2 cylinder and the exhaust valve on the number 3 cylinder. If the valve lash on the intake valves is not 0.006 in. (0.15mm), adjust the valve lash. If the valve lash on the exhaust valve is not 0.010 in. (0.25mm), adjust the valve lash.

1.6L twin cam has shims.
1.8L has HLA , no lash to set.

HLA= Hydraulic Lash adjusters.

I posted this before, search for it. Im only doing 1 engine.

Throttle position sensor and or the fuel pump are bad. Throttle position sensor is pretty cheap and easy to replace. Fuel pump is a pain and a little more expensive.
