    Well if it is the rotary-type, it may not be lubicated by the engine.

    But you are still not out of it, the pump is driven by the engine itself. The SHAFT SEAL is your culprit. It is leaking diesel fuel into your engine.

    It is not your nozzles, leaking nozzles cannot fill up the pan that fast because the excess diesel will be moved out of the chamber as very black smoke. Incomplete combustion because the ideal air-fuel ratio will be exceeded.

    I think this is the most plausible explanation. leak from the ip shaft seal seeping through the o-ring going to the timing gear case, where it mixes with the oil used to lubricate the timing gears , down to the crankcase. You're good turbo, real good. Thanks.

    This is possible with gear driven pumps. Is your ride an isuzu (or toyota B), which other diesels are using gear driven pumps.

    Isuzu. I surmise fuel seeps out of the injector shaft, and the o-ring which seals the injection pump from the timing gear case is also shot. I doubt if its the injectors because it would have resulted in an engine-performance problem. Thanks sir Jayo.

    Actually, kapag binubuksan ko yung radiator cap and mainit na makina, wala na yung bumubulwak kahit na ibirit mo pa rpm. Bumubulwak ang sya kapag malamig pa makina.
