Valve and valve seat wear decreases valve clearance, upsetting valve timing.
NOTICE
If valve clearance is left unadjusted, wear will eventually cause the valves to remain partly open; which lowers performance, burns the valves and valve seats, and may cause serious engine damage.
Valve clearance for each valve should be checked and adjusted in accordance with the Periodic Maintenance Chart.
Inspection and adjustment should be carried out only by a competent mechanic following the instructions in the Service Manual.
