You guys will not believe it, upon closer inspection, I noticed that the hole in the sump was T I N Y!
I had some Q-Bond, so I used the grey powder (for bonding mental) on the hole and then poured the liquid over it to harden it. It seems to have done the trick
I don't think I would have been able to change the sump anyway. I would have had to remove the driveshaft and the exhaust downpipe. Even then, I would have not been able to access 2 bolts as they were hidden by some other contraption.
I'll try to attach some vids to show what was happening before and how it looks now and what I mean by the sump bolts being hidden.
The car seems a little jumpy when idle, neighbour reckoned it was to do with a lack of compression because of the oil leaking, but now there's no leak so not sure. The engine recently was overfilled with oil by the clumsy garage, so I think that may have caused some other damage (i did clean out breather pipes and the spark plugs and the air filter area which all had oil in them)!
