💡 What steps do shops take when rebuilding worn spark plug seats on vintage engines?
Shop techs tackle those damaged ports with a handy tap chaser and fresh sleeves.
- Chase the ruined zone thoroughly to remove rust flakes and preserve casting shape
- Hammer the tapered metal guide deep inside the bore until it snaps flush tight
- Thread the new ignition component down to exact torque specs for even heat transfer
- Verify valve cover clearance early to dodge wiring bundles once you seat the plug
