Good To Know

Q: Can I replace just one valve guide? A: Yes, a single worn guide can be replaced on its own, though many rebuilds replace the full set. Verify stem-to-guide clearance after installation.

Q: What symptoms point to a worn valve guide? A: Blue smoke at startup, valve noise, and dropping compression are common signs. Replacing the guide restores correct stem alignment and sealing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
