🔌 Function

⚠️ Common Signs of Failure

• Oil-filter bypass fault
• Component sticking from sludge
• Scoring or wear
• Bearing damage from incorrect oil regulation

🛠️ Service Notes

• Forms the sealing element in the oil-filter housing pressure-control valve, not a valve-train stem collet — a different application from the paired poppet-valve cones described for most parts sharing this item type
• Works with compression spring 20464676 and O-ring 977004; check the valve bore for scoring and confirm the cone seats and moves freely, since a worn or contaminated bore causes erratic oil pressure rather than a simple leak
