Can broken Rocker Shaft Spring Kit and Valve Stem Oil Seal be replaced without removing the cylinder head in 3.0L and 3.6L V6 engine on GMC Terrain?

Exhaust and intake valve springs for a doubled valve train can be replaced without having to remove the cylinder head of the car, which will take approximately two special tools and a source of compressed air. First, the spark plugs, the valve covers, the cams and the rockers must be taken out. Insert an adapter into the spark plug hole and attach an air hose to this end and the other end must be connected to a compressed air supply. Use compressed air on the cylinder to fix the valves in position against the effects of the liquid. Lightly strike the top of each valve spring retainer to free the valve keeper from the spring retainer Employing a valve-spring compressor, compress the valve spring and extract the keepers by means of needle-nose pliers or magnet. Take off the valve spring and the retainer with utmost care to avoid the pressure of lifting the valve, while the air pressure is still retaining it in the closed position. Take out the previous valve stem seals; it is possible to tell an intake seal from an exhaust seal by how they are designed, and round the upper part of the valve stem with a rubber band or tape to prevent it from falling into the combustion chamber once again, before relieving the air pressure . It is also advisable to examine the valve stem to see if it is damaged and in the process check if the stem binds in the guide. Vibration pressure is then applied to lock the valve back in place and a new valve stem seal is fitted for the intake as well as the exhaust valves without requiring the valve to be pressed up against the top guide. Place the spring and retainer over the valve pushing the assembly just enough to fit the keepers to it, If needed use a little grease to hold the keepers in place. Take the pressure off the spring tool and make sure that the keepers are in place, then detach the air hose and take of the adapter off the spark plug hole. Perform the same for the rest cylinders, and finally fit the rocker arm assemblies, the cam shafts, the timing chains, and the valve covers. Turn on the engine to look for such signs as oil dripping and strange noises, let the car run for at least five minutes then rev it up.

GMC Terrain Valve Stem Oil Seal

The GMC Terrain Valve Stem Oil Seal works to effectively seal the valve guides to prevent engine oil from entering the combustion chambers. This preserves power and emissions quality. The Valve Stem Oil Seal fits tightly around each valve stem, metering a thin film of lubricant that will stop metal-to-metal wear while preventing excessive oil from burning and soiling plugs. As the camshaft lobe activates the opening of either the intake or exhaust valve in the overhead valve or overhead cam architecture, the Valve Stem Oil Seal provides tight oil control so that compression can remain strong and gases escape freely. Even though there is some wear on the lifters, pushrods, or rocker arms (an increase in lash), the oil seal at the valve stem continues to provide a barrier against oil getting in. This helps to minimize misfire and smokiness. For years now, the very same basic style has served in every GMC Terrain engine. That's because the tiny seal's rubber and metal construction already balances flexibility with grip. So, no major variations exist. But consistent reliability does, and that helps each vehicle maintain smooth performance as the miles pile up. So, it's one more reason GMC drivers trust their Terrain engines to the Valve Stem Oil Seal. It may be small, but it sure delivers big protection. The Valve Stem Oil Seal is essential for optimal engine performance.

Each OEM GMC Terrain Valve Stem Oil Seal 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.
