Land Rover Part Number: ERC6337 - Cup Plug - Rocker Shaft End
ERC6337 is a cup plug fitted to the end of the rocker shaft. This cup plug closes the end of the rocker shaft on 4-cylinder 2.25L and 2.5L petrol and diesel engines, sealing the shaft end to help retain lubricant around the rocker assembly and keep contaminants out. Inspect the plug and the seating bore when servicing the rocker shaft and replace if the plug is damaged or leaking.

Frequently Asked Questions
The ERC6337 cup plug seals the open end of the rocker shaft, preventing oil loss and entry of dirt into the rocker assembly. It is normally removed only when the rocker shaft or valvegear is serviced; ensure the seating bore is clean before refitting for a secure seal.
