Assuming you have a 4.0 liter 6 cyl in the truck the answer is no, no valve adjustment is required. there should be 2 rockers held down by 1 bridge ans 2 bolts, those bolts need to be tightened to 16-26 foot pounds.
please respond

There was a water contamination on the rocker arm and top of the rocker arm cover. But the oil on the crankcase has no water contamination does this mean i need to chnge my cylinder head. Please advis


Usually if there is water or moisture in the valve cover but not in the crankcase, you have a venting problem (PCV) or the engine is not warming up to operating temp.

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.

P 2647"A" Rocker Arm Actuator


Your going to need a air pressure regulator or better yet if the ECM found fault price it and replace it
  1. Start the engine, and let it run for 5 minutes, then turn the ignition switch to LOCK (0).
  2. Remove the cylinder head cover.
  3. Set the No. 1 piston at top dead center (TDC).
  4. Move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A should move independently of the secondary rocker arm B.
    1. If the intake secondary rocker arm A moves freely, go to step 5.
    2. If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, then check that the pistons in the secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, then retest.
    3. Repeat step 4 on the remaining intake secondary rocker arms with each piston at TDC. When all the secondary rocker arms pass the test, go to step 6.
    4. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4.0 kgf/cm2, 57 psi).
    5. Inspect the valve clearance.
    6. Install a 10 x 1.0 mm adapter to the inspection hole, then connect the air pressure regulator
  5. With the specified air pressure applied, move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A and secondary rocker arm B should move together. If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, and check that the pistons in the secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, then retest.

Mixed up my rocker arms when replacing my head geasket


the arms for INTAKE should all match, and the arms for EXHAUST should all match. I dont think you can put them on wrong, if you are hitting a piston you need to verfiy the cam timing, I think that is where your problem is.

I presume that you are connecting your Intake manifold to the cylinder head after replacing your intake gasket, if so they are 30ft lbs, and 360 in pounds. Hope that helps
