Super Major thread in engine block

I have a threaded hole behind the injector pump which throws a bit of oil out, therefore I presume it must go through into the crank case, for now I have it bunged up with a rubber bung, and fortunately there is not too much crank case pressure so it hasn't blown out yet....however it would be nice to source the correct bung. The tractor has a minimec pump, and the hole is directly behind it, anyone know what blocks it off? I guess it would be a machine screw, UNC thread? Any help appreciated, if anyone has got one even better! Thanks, Ed

That is a standard machine screw with a little fibre washer. It is the oil feed for the brake exhauster when the engine is fitted to a lorry. It is not shown as a seperate part and used to come in a little bag strapped to the blocks.

was it also used to lubricate the compressor(run off the fuel pump) fitted to industrial engines?

Doesn't seem to throw much oil out for a feed, unless I've got very poor oil pressure! I'll try to get a picture this weekend to make sure its the same place.
Cheers, Ed

They are in the curved cast mountings on the engine block, set back in a hole if its the ones we are talking about.
