617 Injector pump question
Mon, 25/10/2010 - 16:45
Hi Folks,
I have recently bought a OM 617 (non turbo) engine from a 300GD, (the engine is going into a Unimog).
Some parts have been removed from the engine by the previous owner, I have noticed on the injector pump, at the back between the pump and block, there is a small threded hole, looks like somthing was fitted there. I can't work out what should be there, its not the fuel inlet/ outlet so I was thinking maybe a breather pipe? or something? can anyone have a quick look at pump and tell me what I'm missing?
Many thanks
Mike
