Iam getting a minor oil leak from my sump pan which is coming from this hole just in front of the filter cover,it appears like there should be an m6 allen screw fitted in the hole just like the ones on either side of it but the hole seems to be unthreaded and an m6 screw will not tighten into it.
I have come across this on bikes before (where a engine casing or crankcase has a hole which appears that it should have a screw/bolt in it but is actually just a blank hole) so should there be a screw in this hole which has sometime in the past had the threads completely stripped or is it really just originally a blank hole?

That is a weep hole, which tells you if your oil seal (or coolant seal)) in the pump is leaking.

Thanks - I had no idea that it was a weep hole and had never even heard of a weep hole.
Ive done a bit of research on this and other forums and have come up with 3 options
1. fork out for a new or reconditioned pump (by far the most costly option)
2. risk buying secondhand pump of unknown mileage and internal condition
3. providing my impellor shaft is not pitted fit a replacement seal/o ring kit in existing pump
I will probably go for option 3 first.
