Multiple choice — select the best answer

AStretch the shorter springs to match the others
BReplace all valve springs as a complete set
CReplace only the springs with incorrect height
DInstall thicker valve spring shims under shorter springs

✓ Correct answer: B. Replace all valve springs as a complete set Valve springs with different free heights indicate fatigue, sagging, or improper parts. Uneven spring heights can cause valve timing issues and potential engine damage, so replacing all valve springs as a set ensures consistent valve operation.
