Q: How to Address Issues with the Rocker Shaft Spring Kit on Buick Regal?
A: Start work on the oil seal and valve spring replacement only when the engine reaches top dead center of the service cylinder. Start with a valve rocker cover from the right or left side to expose the components underneath. To proceed with the job take out the spark plugs that service the cylinders. Push the Spark Plug port adapter (J 23590) in its designated space on the Spark Plug while the installed air stream stops valve movement. Deepen the valve spring compressor j 38606 onto the valve spring unit to compress it. Remove the valve locks first and push down the spring compressor to unlatch the valve. Replace the valve spring and cap with the Valve Stem Oil Seal after. Check the valve spring for wear and decay. Replace the part if it shows any damage. Set the new oil seal in place on the valve stem until it reaches the valve guide surface. Push the Valve Stem Oil Seal over the valve guide with hand pressure and the valve stem seal installation tool (J 42863). Reinstall the valve spring compressor tool onto the valve spring and repeat compression. Then put in the valve spring and cap as well as the valve locks and ensure each one is fully contained. Unwind the valve spring then take off the Spark Plug port adapter (J 23590) to put back the Spark Plug(s) into the repaired cylinders. Conclusion your work by placing back the push rod and valve Rocker Arm and then fixing the right or left valve rocker cover.
Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on Buick LeSabre?
A: The first step to replacing the Valve Stem Oil Seal and valve spring is to take out the Rocker Arm assemblies and the spark plugs. Turn the engine until the Piston in the servicing cylinder is at the top to keep the valve out of the cylinder. Fit the j 22794 Spark Plug port adapter (J 22794) into the Cylinder Head and supply compressed air into the cylinder so the valves cannot open. With the j 38606 valve spring compressor (J 38606), squeeze the valve spring, and then take out the valve keys, the valve cap, and the valve spring. Lift up the seal from the bottom to take it off the valve stem. To put it in place, place the seal over the valve stem and gently push it onto the guide using only hand pressure and the j 42863. Put the valve stem seal over the valve guide with the j 42863 and then use the j 38606 to put on the valve spring and valve cap, finishing up with the valve keys. Do these procedures for all the valves, then use the j 22794 to release the pressure and take it off the cylinder. The last steps are to put in the Spark Plug and the valve Rocker Arm assemblies.
Q: How to service and repair the Rocker Shaft Spring Kit and Valve Stem Oil Seal on Buick LaCrosse?
A: To service and fix the valve guide seal, begin with the removal of the Starter motor. It is important to install flywheel holding tool according to the en 46106 (EN 46106) standard in order to prevent an attempt to move the Crankshaft because of this movement, it can require disassembly and reassembly of the entire Camshaft timing system. Then, take off the camshafts and rocker arms and the Spark Plug from the corresponding cylinder. Mount the j 39313 (J 39313) Spark Plug port adapter onto the cylinder and attach it to a source of compressed air. Mount the en 46110 (EN 46110) on-vehicle valve spring compressor in upper position on the cylinder and tighten its nut. Remove the valve keepers and loosening the valve spring compressor nut, then you will take out the valve spring retainer and the valve springs. Utilize the en 46116 (EN 46116) valve stem seal remover/installer to remove the valve stem seal. Instead, repair with the en 46116 (EN 46116) again to install the new valve stem seals and the valve spring and retainer. Replace the en 46110 (EN 46110) on top of the valve spring and tighten its nut before replacing the valve spring keepers. Remove the en46110, disconnect the j39313 (J39313) from the air source and take it out. Finally, replace the spark plugs, rocker arms, and camshafts, remove the en46106 (EN 46106), and place the Starter motor.
