🔌 Function

The sleeve forms the working bore in which the oil-control plunger moves. It keeps the plunger aligned, meters leakage around the moving element and positions the plunger relative to the oil galleries so the filter/cooler bypass circuit operates at the intended pressure.

⚠️ Common Signs of Failure

• Plunger sticks or moves sluggishly
• Scored bore or metal transfer on the sleeve surface
• Unstable oil pressure as the valve hunts or leaks internally
• Wear creates excessive clearance and uncontrolled bypass flow
• Contamination prevents the sleeve seating fully in the housing

🛠️ 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
