Location of Pushrods - Montana Pontiac Cars & Trucks

The intake valve pushrods measure 144 mm (5.75 in) long.
Exhaust valve pushrods measure 152.5 mm (6.0 in) long

their is no sequence for pushrods only headbolts your pushrod should be placed at the same location that they we're removed

Hi there:

Rocker Arms & Pushrods

Removal & Installation

3.1L & 3.4L Engines
Left Side

1. Before servicing the vehicle, refer to the precautions section.
2. Drain the cooling system to a level below the coolant pipe on the front of the engine.
3. Remove or disconnect the following:
   NOTEKeep the pushrods in order. Intake pushrods are 5 3 / 4 inches long and exhaust pushrods are 6 inches long.
   
   
   Negative battery cableSpark plug wiresHeater bypass pipePositive Crankcase Ventilation (PCV) valve and hoseRocker arm cover
   
   
   Rocker arms and pushrods
   

To install:

1. Lubricate all the valvetrain components with engine oil.
2. Install or connect the following:
   
   Pushrods and the rocker arms. Torque the bolts to 24 ft. lbs. (32 Nm).Rocker arm cover using a new gasket. Torque the rocker cover bolts to 89 inch lbs. (10 Nm).PCV valve and hoseHeater bypass pipe. Torque the screw at the water pump to 106 inch lbs. (12 Nm), the bolt at the cylinder head corner to 18 ft. lbs. (25 Nm) and the nut to 18 ft. lbs. (25 Nm).Spark plug wiresNegative battery cable
   
3. Refill the cooling system.
4. Start the vehicle and verify no leaks.

Hope this helps.

The intake pushrods and exhaust pushrods are different lengths. To distinguish the different pushrods, paint has been used, although this paint may be hard to identify after prolonged use. The intake pushrods are color-coded orange and are 6 in. (152mm) long. The exhaust pushrods are color-coded blue and are 63/8in. (162mm) long.

Here is a picture of the cylinder marking:

The exhaust pushrods are the longer ones. The intake pushrods are the shorter ones.

1. Install the pushrods in their original location, making sure they seat in the lifter sockets.
   
2. Install the rocker arms and ball, then tighten the nuts to 14-20 ft. lbs. (19-27 Nm).

Keeping the pushrods in order on an engine isn't because of certain ones being longer than others. Pushrods develop an unique wear pattern with the lifter, and if you change them around, they won't seal anymore, and won't carry oil to the top of the valve train. This will result in your valve guides wearing out prematurely, and causing excessive wear. If they haven't been kept in order, you should replace the lifters and pushrods.

You may be able to use them,there should be enough adjustment to make them work.FordMotorsports and Crane make a pushrod that is 8.640 which is what I used with those rockers.To check fit install 1 pushrod and 1 rocker on #1 cyl turn the engine over by hand 2 revolutions and then check and make sure the rocker tip is dead center on the valve,if it is you're good to go.

Important: Place the valve train parts in a rack in order to ensure that they are installed in the same location from which they were removed. Intake pushrods measure 144.18 mm (5.68 in) long. Exhaust pushrods measure 152.51 mm (6.0 in) long

No, it's fairly easy, just remove the valve cover, unbolt the rocker arms, remove pushrods. Make sure you have correct parts and compare length of new ones to old ones. Too long of a pushrod and you could have major damage. Slide pushrods into lifters, you can look down through the head and see the lifter. You can also feel when the rod is in the lifter correctly. Install rockers in reverse trying to put back in exact location. I recommend torqing these, you'll have to find the spec. You could spin the engine with coil unhooked so it won't fire before you put the valvecover back on to make sure they're all moving the same. Install valve cover, etc, your done.
