There should be two lengths. One size for intake and other size for exhaust. Six of each size. Exhaust are longer. Here is picture, exhaust are one and intake are two.

When assembling an engine the parts have to go back to there original place in order from where they came. The valve adjustment has a great deal of lash that is due to the use of hydraulic lifters. This is made up for by using different length push rods.
I have attached the valve adjustment directions from a service manual.
You will have to move the push rods around until you get them to have the same general amount of lash. This has to be within the amount of lash that the adjusters can handle.

Let me know if you have any questions.

Front wheel drive automatic 200,000 miles.

My car makes a ticking noise on top of the engine and never goes away even if drive 100 km. Could be lifters but runs great. How do I solve problem are these lifters adjustable?

Try torquing the rocker arm bolts to specs do not work could be lifters or the camshaft itself.

I replaced head gasket I did not know the push rods were different lengths. I need a lesson how to get push rods in right place.

The intake valves use the short ones and the exhaust valves use the longer ones as they are farther away from the cam/lifters.

They are on the rocker arms. Short ones go on the intake valve.

I have 1997 Chevrolet Malibu 3.1L V6 engine. I did a rebuild on the engine I was informed that the push rods might not be in their correct position. The manual that I have says nothing on the correct positioning of these rods. Is there anyone that can tell me exactly how I go about placing those in the correct position? Please make it girl proof, lol.

Okay, there are two different length push rods. If you look at the cylinder head there are three valves closer to the center of the engine and three closer to the exhaust manifold. Long push rods go to the farthest away from the center of the engine. Short to the closest, almost like a big-block Chevrolet "semi-hemi".

Thank you. I think that we put them in wrong. I think that we put them in a long one and a short one switching off every hole. So a long one then a short one and so on. So by your explanation I believe that we totally put them in wrong. Thanks again and I will let you know what the outcome is.

Okay, so we checked the push rods and that was not the cause of the engine not starting so what is next? I know there is spark. I checked that already and the gas is fine. What next? The computer had a code that sad p1406. I have not been able to find that code anywhere. Does that mean anything?

Be sure everything is plugged into the coil pack. There are I believe three connectors. One of them comes from near the top of the transmission, that might be the one you missed. Hopefully.

You have to take the rocker arms off as well as valve covers.

See if lifter is out, if it is you will need to take intake off. There are also intake experience push rods different lengths.

I did remove rocker arm also, I think what I did wrong, I was going straight down instead of angling to left six or eight degrees. Push rod to short, cannot hold onto it. Sure do not want to remove intake. Thanks for information, any tips will be appreciated.
