Remove the spark plugs and the valve covers, camshafts and rocker arms. Thread an adapter into the spark plug hole and connect an air hose from a compressed air source to it. Most auto parts stores can supply the air hose adapter. Apply compressed air to the cylinder. The valves should be held in place by the air pressure. Using a socket and a hammer, gently tap on the top of each valve spring retainer several times, then use a valve-spring compressor to compress the spring. Remove the keepers with small needle-nose pliers or a magnet. Remove the valve spring and retainer. Remove the old Valve Stem Oil Seals, noting differences between the intake and exhaust seals. Wrap a rubber band or tape around the top of the valve stem so the valve won't fall into the combustion chamber, then release the air pressure. Inspect the valve stem for damage. Rotate the valve in the guide and check the end for eccentric movement. Move the valve up-and-down in the guide and make sure it does not bind. Reapply air pressure to the cylinder to retain the valve in the closed position, then remove the tape or rubber band from the valve stem. If you're working on an exhaust valve, fit the new exhaust Valve Stem Oil Seal on the valve stem and press it down over the valve guide. If you're working on an intake valve, install a new intake Valve Stem Oil Seal over the valve stem and press it down over the valve guide. Install the spring and retainer in position over the valve. Compress the valve spring assembly only enough to install the keepers in the valve stem. Position the keepers in the valve stem groove. Apply a small dab of grease to the inside of each keeper to hold it in place if necessary. Remove the pressure from the spring tool and make sure the keepers are seated. Disconnect the air hose and remove the adapter from the spark plug hole. Repeat the above procedure on the remaining cylinders. Install the rocker arm assemblies, camshafts, timing chains and the valve covers. Start the engine, then check for oil leaks and unusual sounds coming from the valve cover area. Allow the engine to idle for at least five minutes before revving the engine.

Valve springs break and valve stem seals can be changed without removing a cylinder head, generally, two special tools and compressed air. First, the spark plugs and valve covers shall be unplugged and by turning the crankshaft of the vehicle, the piston number one should be on the compression stroke TDC. Take out the rocker arms for the number one cylinder, insert an adapter into the spark plug hole and attach an air line from compressed air. Using compressed air jam the valves on the cylinder and for the cylinder head hole stuff the shop rags so as to avoid oil and other parts or tools to fall on the engine. Lightly hammer on the heads of the valve springs with a soft-faced hammer to free the valve keeper from its seat on the spring retainer with a magnet or with small needle-nose pliers using a valve-spring compressor. Lift off the valve spring and the retainer and if air pressure cannot keep the valve closed the valve face or seat may be bent and will require the cylinder head to be pulled for repairs. Take out the previous valve stem seals with the typical variation between the intake and the exhaust seals and circle the head of the valve stem with a rubber band or some piece of thin tape so as the top of the valve stem won't fall off into the combustion chamber before one can release the air pressure. Check the valve stem for signs of wear particularly the smooth running of the stem in the guide; if this fails the head will have to be unbolted for further repair. Pump in a little air pressure to lock the valve in its closed position; then, place the new valve stem seals over the ends of the intake and exhaust valve guides. Place the keepers alongside the retainer and over the valve, compress the valve spring assembly enough through to seat the keepers and use a drop of grease just to ensure that they are well in place. Retract the keepers and take off the pressure from the spring tool, thereafter, take off the air hose and remove the adapter from the spark plug hole. Perform the same on the other cylinders, with each piston at TDC on the compression stroke when air pressure is applied and the rocker arm assemblies and valve covers fitted back.

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.
