You can't it is nonadjustable, The timing is controled by the computer. And there is no reason to adjust it unless you had the distributor out of the engine and in that case you will need to turn it by hand enough to get it running, and that is called the base timing. Then you will notice that the check engine light is on and you will need an OBD2 engine scanner hooked up to the truck and then go into the timing mode and ajust the timing to factory spec. and the scanner will let you know when you have the timing correct. The check engine light will go off when you have the timing right. Then the computer will do the rest.

∙ 12y agoWhen you line up the 2 marks, The 1 on the timing cover and the 1 on the balancer is just a reference when you bring #1 pistion up on the compression stroke, Then you line those 2 marks up so you know it is at TDC / Top Dead Center.
You can not set the timing with a timing light on a 98. It is not adjustable, It is controled by the computer. If you had the distributor out then the only thing you can do is set the base timing and you do that by ear good enough to get it running. Then you have to get a OBD2 engine scanner and hook it up and go into the timing mode and adjust the timing by moveing the distributor by hand until the scanner shows that it is within specs. Then your done and the computer will take over from there.
If you are just wanting to set the timing, then there is no reason too. If the cam and crank get out of time then the check engine light will come on. And if the timing is out then the scanner will tell you.

How do i set the timing if i didn't mark the distributor on a 1996 350 vortec?
The timing on that engine is controled by the computer. You can not use a timing light. The only thing you can do is move the distributor enough to get the engine to run and have power and that is called the base timing. When it does run and the engine light is not on then you got lucky, but if the check engine light comes on, then you will have to get an engine scanner and hook it up and go into the timing mode and move the distributor until you get the cam and crank in time. The scanner will show you when it is in time and the engine light will go off. Tighten distributor and your done. The computer will do the rest.
Where is the oil pump for the 2003 Chevrolet 2500 hd with a 6.0 vortec motor?
It is on the front of the engine, behind the timing cover where the timing chain and gears are. You will have to remove the front of the engine to get to it.It is not in the oil pan were they use to be. It now slides over the front of the crankshaft.
What is the degree timing mark for 1965 327 small block Chevy?
the timing mark is an engraved line on the flywheel. there should be a metal flap offset of the flywheel with markings for A (advanced), O (ontime), and R (retarded). use a timing light connected to the spark plug wire for #1 cylinder. That is how it is in my 65 impala 327 Minor correction is that the timing mark is on the front damper not the flywheel.
Timing cover replacement on Chevrolet 350 vortec?
The vortec used a plastic timing cover with the crank sensor mounted in it at the lower end. The cover and gasket come as one part and are meant to be replaced when removed. Although I will say that if you clean it properly and dry it well with brake cleaner and use a quality sealer you will be ok reusing it. it is located under the water pump and against the front of the block covering the timing chain, gears and reluctor wheel for the crank sensor.
