Technical Notes: Valve train
Valves, guides, seats, springs, and rocker components control gas exchange in the cylinder head. Wear in the valve train shows up as compression loss, rising exhaust temperatures, or changes in valve clearance between service intervals.
When This Type of Part Is Usually Replaced
- valve clearance changes quickly between adjustments
- compression is low on one or more cylinders
- valves or seats show burning, pitting, or recession during head overhaul
Checks Before Ordering
- Valve guides and seats are matched to the valve stem and head; order them per cylinder head
- Replace valve stem seals whenever valves are removed
- Inner and outer valve springs are usually separate part numbers
