Valve: Service and Repair
REMOVAL
1. With cylinder head removed, compress valve springs using a universal valve spring compressor.
2. Remove valve retaining locks, valve spring retainers, valve stem seals and valve springs.
3. Before removing valves, remove any burrs from valve stem lock grooves to prevent damage to the valve guides. Identify valves to insure
installation in original location.
4. Inspect and clean the valves.
INSTALLATION
1. Coat valve stems with clean engine oil and insert in cylinder head.
Valve Stem Oil Seal Tool
2. Install new valve stem seals on all valves using a valve stem seal tool. The valve stem seals should be pushed firmly and squarely over valve guide.
CAUTION: When oversize valves are used, the corresponding oversize valve seal must also be used. Excessive guide wear may result if oversize
seals are not used with oversize valves.
3. Install valve springs and retainers. Compress valve springs only enough to install locks, taking care not to miss-align the direction of compression.
Nicked valve stems may result from misalignment of the valve spring compressor.
CAUTION: When depressing the valve spring retainers with valve spring compressor the locks can become dislocated. Ensure both locks are in
the correct location after removing tool.
Checking Spring Installed Height And Valve Tip Height Dimensions
4. Check the valve spring installed height B after refacing the valve and seat. Make sure measurements are taken from top of spring seat to the
bottom surface of spring retainer. If height is greater than 38.75 mm (1.525 inch), install a 0.762 mm (0.030 inch) spacer under the valve spring
seat to bring spring height back within specification.
