Push valve out, keeping it in order for
reassembly in the same guide.
Measure free length of the inner and outer
springs with a Vernier caliper, |||.1. Check
spring for squareness as shown in |||.2.
Replace spring if measurements are out
of specification.
Remove valve seals. Note: Replace seals
whenever the cylinder head is disassembled.
Hardened, cracked or worn valve seals will
cause excessive oil consumption and carbon
buildup.
INSPECTION
Remove all carbon from valve with a soft
wire wheel.
Check valve face for runout, pitting, and
burnt spots. To check for bent valve stems,
mount valve in a drill or use “V” blocks and
a dial indicator.
