1H762     15.A.10   Adapter for oil pipe -Fin.(E)GB11297 -(Changed to 1H922 at (E)GB11298)

This adapter is used at the right rear corner of engine block where the rear cross drilling brings out pressurized oil from the oil pump (after the pressure relief valve). Purpose of the long narrow tube extension is to block oil passage from the rear drilling into the main oil galley, so oil must come out into the external oil pipe routing to the oil filter. With installation of an oil cooler, this fitting connects to a flex hose running to the oil cooler, and after the cooler another flex hose going to the oil filter.

The fine thread on the outboard end is for the AN hose connector. The thread on the engine side (with the seal washer) is a BSP standard thread.

Later production cars used adapter 1H922 which has an extended neck between bottom mounting thread and the wrench hex. The later fitting makes it easier to use two wrenches when attaching (or detaching) the connectiong pipe or hose.
