Hi,
I carried out a leakback test on all four injectors by disconnecting the electrical connections and the return hoses to the injectors, clamping the return hose by No. 1 injector and disconnecting the camshaft sensor. As this was the first time I had done this test I did not have any idea of the quantity of diesel that would be expelled if leakback was occuring. When I spun the engine the wells on top of all the injectors filled up but not under any great pressure. With the electrical connection disconnected would I be right in thinking there should be no leakback at all and the tops of the injectors should be dry? Also what rate of flow of diesel signals mild leakback or bad leakback ?

Regards,
Aghadown
