• Damaged threads, terminals, locking tabs or sealing face
• Corrosion, contamination or heat damage
• Repeated disconnection or inability to retain the mating part

🛠️ Service Notes

• Check which way round the sleeve goes before the old one comes out — sleeves are rarely symmetrical, and one end is usually chamfered or stepped to lead into the bore
• Clean and inspect the bore it seats in; a sleeve takes its final shape and fit from that bore, so corrosion, scoring or an oval bore will spoil a new part
• Draw or press the sleeve in square with the correct tool rather than driving it in — a sleeve started crooked will nip, and the material displaced by a hammer blow never fully recovers
• Renew any O-ring, seal or gasket that seats against the sleeve while it is out, and lubricate on assembly as the manual for your engine specifies
• Confirm the sleeve is fully home to the depth or flush condition the workshop manual gives before reassembling anything on top of it
