Valve Cover opens, closes or modulates a passage in the engine or transmission circuit. Spring rate and orifice size are calibrated to the application, not selected by size.
Replace the Valve Cover when the valve does not return freely, when the seat is pitted, or when a solenoid that drives it has already been replaced. Debris in the circuit damages the new one the same way.
The Valve Cover in this listing carries part number 12735921 and sits in the Cylinder Heads & Valvetrain category. The number stamped on the original part is the only reliable cross-reference.
This is genuine GM stock, supplied for the Valve Cover with the manufacturer number intact so the reference on the box matches the catalogue.
