Ford Excursion Valve Stem Seal
The Excursion Valve Stem Seal by Ford is responsible for preventing oil from entering the combustion chambers while allowing each valve to slide smoothly. This allows maximum power output while minimizing consumption. Each seal, which is positioned around the valve stem, forms a tight barrier between the valve stem and the cylinder head to keep the lubrication on the stem and not drip on the piston crown, where it could burn and foul the plugs. When the camshaft, either block mounted in an OHV layout or head mounted in an OHC arrangement applied on different years of the Excursion, lifts the valve via lifters and pushrods or followers, the seal flexes with the stem, maintaining clearance. Thus, compression remains strong on every stroke. Since wear in cam lobes, pushrods, or rocker arms can widen lash and pound components, a good Valve Stem Seal will also help limit heat transfer that could overheat and warp valves. A fresh Valve Stem Seal preserves clearances. Ford specifications for the Excursion are tight on the Valve Stem Seal lip to control consumption across all Excursion engines. The small part highlights Ford detail and attention and uses a proven Valve Stem Seal to support Ford performance.

Ford Excursion Valve Stem Seal Parts Questions & Experts Answers
- Q: How can broken valve springs and defective valve stem seals be replaced without removing the cylinder heads on Ford Excursion?A:Damaged valve springs and worn valve stem seals are, therefore, easily done without stripping the cylinder heads. One method involves using of a tool recommended by the manufacturer to remove valve springs and seals without camshafts removal while the other method involves the use of a readily available tool and involves removal of the camshafts. The two methods give the same outcome but using the manufacturer's approach is less straining if the right resources are in the manufacturer's procedure. For this operation, often a compressed air source is required, so be sure to collect the necessary equipment in advance. First, you have to pull out the valve cover and spark plug from the cylinder that you know is problematic; you have to rotate the crankshaft until the piston gets on the compression stroke. Air hose adapter should be screwed into the spark plug hole, and the compressed air should be used to retain the valves. Cotton should be placed in the cylinder head holes so that no parts fall in the engine. As with the method utilizing special tools, the usage of a valve spring spacer is mandatory, so that the valve seal received damage during compression. When the spring is compressed the rocker arm is taken off and this is followed by the keepers, spring retainer, the spring and the stem seal of the valve. If pressure cannot retain the valve closed any further fixes may be required. In the other procedure the camshaft is withdrawn and a clamp type valve spring compressor used in compressing the spring and the removal of the keepers, spring retainer and stem seal. What's more, to ensure that this valve can be installed successfully, a rubber band or tape should be tightly placed around the valve stem so that it will not fall, after that the air pressure should be applied so that the valve will be ensured to be closed. The top is lubricated, a new seal is put, and the garter spring has to be correctly placed on the valve stem. The valve spring retainer is then placed followed by the keepers placing them in the groove created. After release of pressure on the spring tool, the air hose is disconnected and the spark plug and ignition coil restored. Lastly, the procedures are the reverse of installation steps and starting of the engine and tighten the bolts while observing the car for oil stains and unusual sounds.
