Oldsmobile 22530557 Cylinder Head Assembly

Check all parts of the valve mechanism for cleanliness and absence of carbon and dirt; that the bare cylinder head or flat is clean and not in contact with/carry abrasive materials used for valve grinding or reaming. There should be an insertion of a valve for the right port and the spring and damper, and shield, and cap of the valve spring of that specific cylinder should be assembled. Place the assembly with the over the valve stem and utilize the valve spring compressor to hold it in place. Make the locks to fit tightly in the upper groove of the valve stem then put the value locks and lastly release the compressor. Ensure the height of the valves springs installed is checked by using a small thin scale from the top of shim if fitted, the spring seat to the top most point of the valve spring or the valve spring shield if fitted. If required, one may place spacer under the valve spring to get the right figure, but to coming in with an installed height less than the stipulated minimum length is prohibited. If the spring is too short, it is mounted for a new one. Last but not the least put a new oil seal with the flat side facing down on the lower groove of valve stem but not twisted.

Check that all parts of the valve mechanism are clean and free from carbon and dirt; the bare cylinder head should be clean with no abrasive particles which were used on valve reconditioning. Install a valve in the right port and fit the valve spring assembly of that cylinder which includes; spring, damper, shield, and cap. Fit the valve spring compressor over the valve stem and tighten to squash the assembly together. Mount a new oil seal in the lower groove of the valve stem, it should lie flat and should not be twisted. After that, tighten the valve locks and then open the compressor where the lock must sit well in the upper catch of the valve stem. Measure the installed height of the valve springs by using a narrow thin scale from the top of the shim if fitted, or from the spring seat to the top of the valve spring or spring shield if used. Should the valve spring installed height be slightly less than the minimum specified length, shims may be inserted under the spring to provide the required installed height but the latter should not be less than the minimum specified length. If the spring is rather short, it is necessary to change it to a new one.

When removing the right cylinder head, additional steps include loosening the alternator belt and disconnecting the wiring to remove the alternator.

Use parts cleaner to remove all sludge and dirt from these components, working on one set at a time and returning each set to its numbered location on your box or rack.

If the engine has been removed from the car, disregard the following steps which do not apply.

Consider rebuilding alternatives, and if choosing to overhaul the cylinder heads, understand the necessary steps, tools, and replacement parts.

Clean all carbon from the combustion chambers and valve ports using GM tool J-8089 or a similar cleaning attachment available at auto parts stores.

Begin by removing the intake manifold and draining coolant from the engine.

Thoroughly clean off the engine block surface, ensuring no foreign matter, dirt, or gasket pieces have fallen into the engine cylinder bores, bolt holes, or valve lifter area. Use an air hose to clean out the bolt holes if possible.

New and rebuilt cylinder heads are commonly available for GM engines at dealerships and auto parts stores, making it practical and economical for home mechanics to purchase replacement heads and install them.

Begin by removing the intake manifold and the exhaust manifolds. Next, remove the lower mounting bolt for the alternator and set the alternator aside while removing the lower bracket.

Install a new oil seal in the lower groove of the valve stem, ensuring it is flat and not twisted.

If warpage exceeds 0.006 inches at any point with a straightedge spanning the entire head, resurfacing is necessary.
