Individual Cylinder Valve / Rocker Cover - Cummins B-Series Style (Unverified) - Used

Individual cylinder valve / rocker cover (single center-bolt style) for a diesel engine. Application: unverified — visually consistent with the Cummins B-series (4BT 3.9L / 6BT 5.9L) family of per-cylinder valve covers and their industrial/agricultural equivalents, but no manufacturer name or part number is legible on the piece, so no fitment is claimed. Condition: used, untested take-off. Solid one-piece cover with a continuous gasket flange, single center fastener hole with machined seat, and internal load-spreading ribs; worn exterior finish with light surface pitting and paint loss, no cracks or distortion visible. Gasket and hardware are not included. Sold by photographs, dimensions, and visible features only. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
