Oil leak at fuel pump

The oil will not flow to the cooler if it is cold, it will lift the relief valve in the remote valve block and return to sump, via dipstick tube. This might explain why when you drove the carrier, it did not show signs of leaking through the lift pump hole under the diaphragm, as it was hot oil and not flowing back via the tube. If I could find my T16 book I might be more sure but looking at a Windsor book at present.

thanks Richard. It has been very hot since the leak started so I think either the thermostat in the cooler has stuck, and reduced the flow causing the relief valve to operate, or as mentioned in my last post maybe I followed the schematic and hooked up the cooler pipe correct for the TM diagram, but the wrong way for my system which as you can see it exactly the oppostite way around.

Very odd!! On top of the Dingo playing up, I am not having a good few days!
