How can you replace broken Rocker Shaft Spring Kit and Valve Stem Oil Seal without removing the cylinder head on 2.2L four cylinder engine on Chevrolet Blazer?

Special tools and a source of compressed air are necessary to enable you change broken valve springs or faulty Valve Stem Oil Seals without taking off the cylinder head. Start by removing the spark plug from that particular cylinder (or all plugs if changing all seals). One cylinder at a time, start with number one cylinder at TDC, following the firing order. Put an adaptor into the spark plug hole, then link it up with an airline hose for supplying compressed air. Unbolt the rocker arm nut, remove the pivot ball and rocker arm from the leaking valve and take out the push rod. Supply compressed air to the cylinder in order to retain valves. Bring down valve spring compressors so that they can squeeze springs and hence release them from keepers. Get rid of spring retainer and valve spring, then replace guide seal making sure it is pushed downwards onto top of guide tube. Apply engine oil on valve stems and insert spring back followed by retainer forcing springs to their right places using locking tabs. Disconnect air hose, unthread adapter then reassemble rocker arm along with pushrod, spark plug and finally valve cover. Turn on engine and look for oil spills as well as strange noises near that head cover area. Failure of pressure to hold down valve when closed may suggest either damage in valve itself or its seat or both thus meaning extensive repair by removing head.

Chevrolet Blazer Rocker Shaft Spring Kit

The Chevrolet Blazer Rocker Shaft Spring Kit is a small safety and alignment device that holds rocker arms centered on the shaft so valve motion is precise and power stays strong. In the overhead valve layouts, the camshaft drives lifters and pushrods to meet the rocker arm. The Rocker Shaft Spring Kit springs press each rocker against spacers to limit side play that raises clearance and can bend pushrods. The Rocker Shaft Spring Kit keeps the rocker lineup stable. This allows the valve springs to hold their designed seat pressure. As a result, the risk of valve float is greatly reduced, which robs horsepower in Chevrolet trucks at higher revs. There are two styles, the early split-steel type and a lighter tempered wire version that allows oil to pass freely for cooler operation across the Blazer line. Each Rocker Shaft Spring Kit, regardless of style, utilizes simple spring tension rather than complex hydraulics, so installation is relatively simple and long-term durability matches the million-plus cycles that the valvetrain sees. If your Chevrolet Blazer features an OHV engine and its springs are showing wear, the Rocker Shaft Spring Kit will replace those springs to ensure correct rocker positioning, no valve timing inaccuracies, and to prevent excessive clearance damaging your cams, pushrods, and pistons.

Each OEM Chevrolet Blazer Rocker Shaft Spring Kit we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
