Can broken Rocker Shaft Spring Kit and Valve Stem Oil Seal be replaced without removing the cylinder head in 2.5L four cylinder engine on Pontiac Grand Prix?

Valve springs and valve stem seals that are broken or defective do not have to be replaced with the cylinder head removed, and the job requires generally two special tools and a compressed air line. In the absence of compressed air, a piece of nylon rope can be utilised in order to prevent the valves from falling into the cylinder. Start with unscrewing the valve cover along with the spark plug from the cylinder concerned, if it is an individual cylinder valve stem seal replacement, or all spark plugs if you're replacing all the valve stem seals. Rotate the crankshaft until the piston is at TDC on the compression stroke, although the operation is done cylinder by cylinder in the firing sequence. Insert a threaded adaptor into the spark plug hole while connecting an air compressor to the other terminal of the air hose. The bolt holding the defective valve, pivot ball, and rocker arm should be unscrewed, and the pushrod ought to be withdrawn. Use compressed air on the cylinder, thereby restraining the valves with the barrel pressure. Should air pressure not deliver, a valve job might be in order. Otherwise, place the piston slightly before the top dead centre, push a nylon rope into the combustion chamber and turn the crankshaft until it meets some opposition. Employ shop rags so that the parts do not drop into the engine then compress the valve spring using a valve spring compressor and pull the keepers. First you should take off the spring retainer and the valve spring afterward the valve guide seal. If the pressure keeps the valve closed, the valve face or seat may get ruined, and thereby one has to remove the cylinder head. Loosen a rubber band or some tape around the valve stem so that it does not fall off then deflate the tire. Visually check for some degree of wear on the valve stem and then check that it rotates with ease in the guide. Admit air pressure in order to reseat the valve, coat the valve stem with engine oil and put on a new valve guide slug. Place the spring over the valve, put the spring retainer in place, push the spring down and put the keepers in place and grease them if required. Pull the air hose off, take the adapter out and replace the rocker arms and the push rods, spark plugs and the wires. Last of all, fit back the valve cover, if required tighten the bolts, start the engine and do look out for any dripping of oil or any strange noise.
