The rockers should be the same, shouldn't matter, they aren't different sized correct? They do not change variance or timing, shouldn't matter which you use.

I have a 1973 Ford F 100 had an oil leak coming from the intake manifold so what taking the manifold off I notice I had to take the rocker arms off now I've taken the pushrods off and I'm ready to...


You can do it statically or dynamically. For static adjustment, make sure the valve is way off the cam lobe, tighten until there is a drag when twisting the pushrod. Make sure the rod is properly seated at both ends. Then add 1/2 to 3/4 turn.
For dynamic adjustment, put them all on and take out play. Cover the exhaust manifolds and compartment where the oil will squirt. Start the engine and adjust each one until it just stops clicking. Back off to let it click again and then tighten again until it just stops clicking. Do this on each rocker, and then add 1/2 - 3/4 turn to all. This is messy but more accurate. Replace the oil that was lost.

I Need The Pushrod Format For My 98 Chevy Venture.


The shorter pushrods go on the rocker arms that are closer to the intake side of the head, the longer ones go on the rocker arms closer to the exhaust side of the head. The camshaft is dead center in the engine, the further away from the cam the rocker arm is, the longer the pushrod needs to be.

Well we tried adjusting the valves and then it will start and make a werid noise and then will be about to shut off and it doesnt sound right plezz can you help me? its a 1997 gmc 5.7 1500


With the Engine in the number 1 firing position, adjust the exhaust valves for cylinders number 1, 3, 4, and 8 and the intake valves for cylinders number 1, 2, 5, and 7.
Turn the valve rocker arm nut counter clockwise until the valve lash is felt in the valve pushrod.
Turn the rocker arm nut clockwise until all of the valve lash is removed (zero valve lash).
Zero valve lash can be felt by moving the valve pushrod up and down between your thumb and forefinger until there is no more up and down movement of the valve pushrod.
When all the valve lash is removed, then turn the valve rocker arm nut clockwise 1 additional turn (360 degrees).


With the engine in the number 6 firing position, adjust the exhaust valves for cylinders number 2, 5, 6, and 7 and the intake valves for cylinders number 3, 4, 6, and 8.

Follow the same steps as above.

I have a 1999 Buick Century V6 3100 that I had to replace the intake gaskets due to antifreeze leaking into and out of the engine. When I had it all apart I noticed the very first lifter #2 cylinder...


If the engine oil was full of antifreeze when the intake gasket went bad, then there is a good chance that there may be some cam and/or lifter damage. A more likely cause of your problem would be that the push rods got mixed up when you put it back together. The intake and exhaust rods are different lengths. If this is the case, and you have turned the engine over, there is a good chance that you now also have a bent pushrod and intake valve. The exhaust pushrod is the longer one and if you mix them up, the piston will contact the intake valve because it will not be able to close due to the longer pushrod. This will bend or break the pushrod and bend the valve stem.

Rocker arm torque specs on a 97 gmc jimmy 4.3


  1. For the 4.3L engines which are equipped with screw-in type rocker arm studs with positive stop shoulders, tighten the rocker arm adjusting nuts against the stop shoulders to 20 ft. lbs. (27 Nm) on 1994-96 models and 18 ft. lbs. (25 Nm) on 1997-99 models. No further adjustment is necessary, or possible.
  2. For most 4.3L engines which are not equipped with screw-in type rocker arm studs and positive stop shoulders, properly adjust the valve lash. For details on valve lash adjustment, please refer to the procedure in Routine Maintenance . (see below)
4.3L Engine

The 4.3L engines may be equipped with either of 2 rocker arm retaining systems. If your engine utilizes screw-in type rocker arm studs with positive stop shoulders, no valve lash adjustment is necessary or possible. If however, you engine utilizes the pressed-in rocker arm studs, use the following procedure to tighten the rocker arm nuts and properly center the pushrod on the hydraulic lifter:
  1. To prepare the engine for valve adjustment, rotate the crankshaft until the mark on the damper pulley aligns with the 0? mark on the timing plate and the No. 1 cylinder is on the compression stroke. You will know when the No. 1 piston is on it's compression stroke because both the intake and exhaust valves will remain closed as the crankshaft damper mark approaches the timing scale.

Another method to tell when the piston is coming up on the compression stroke is by removing the spark plug and placing your thumb over the hole, you will feel the air being forced out of the spark plug hole. Stop turning the crankshaft when the TDC timing mark on the crankshaft pulley is directly aligned with the timing mark pointer or the zero mark on the scale.
The valve arrangement is as follows:



E-I-I-E-I-E (right bank-front-to-rear) E-I-E-I-I-E (left bank-front-to-rear)

  1. With the engine on the compression stroke, adjust the exhaust valves of cylinders No. 1, 5 & 6 and the intake valves of cylinders No. 1, 2 & 3 by performing the following procedures:
    1. Back out the adjusting nut until lash can be felt at the pushrod.
    2. While rotating the pushrod, turn the adjusting nut inward until all of the lash is removed.
    3. When the play has disappeared, turn the adjusting nut inward 1 3 / 4 additional turns.

  2. Rotate the crankshaft one complete revolution and align the mark on the damper pulley with the 0? mark on the timing plate; the engine is now positioned on the No. 4 firing position. This time the No. 4 cylinder valves remain closed as the timing mark approaches the scale. Adjust the exhaust valves of cylinders No. 2, 3 & 4 and the intake valves of cylinders No. 4, 5 & 6, by performing the following procedures:
    1. Back out the adjusting nut until lash can be felt at the pushrod.
    2. While rotating the pushrod, turn the adjusting nut inward until all of the lash is removed.
    3. When the play has disappeared, turn the adjusting nut inward 1 3 / 4 additional turn.

1992 chevy lumina eurosport- not the same as a plain lumina-are the push rod assembly for the eurosport. on the front why do the lifters stick up higher when you put the push rod in and put the rocker arm...


ok i understand what you are saying now.

the euro sport is the same as the lumina base just with a body kit, stiffer suspension, and dual exhaust.

but on the 3.1 engine the pushrods are all the same length, but depending on the stroke each cylinder is on the pushrod may be in a different position.

you are assuming that every pushrod should be in the rest state. that is not true. if the cylinder you are installing the pushrod for is on the intake stroke when you install the intake valve pushrod and tighten the rocker arm nut the valve will procede to open like it should be open for the intake stroke.

this is normal and its nothing wrong with it.

Valve noise


I am from the old school. Start the engine with the valve covers off, back off the rocker nut until the rocker starts tapping then slowly tighten nut until tapping stops then go an 1/8 of a turn tighter. Repeat the same for the rest.I know it will be very messy and you have to watch the oil on the exhaust manifolds for a fire. There will be a lot of smoke. What I do is cut out sheet metal and use it as a shield so the oil does not flow over the head as much.
