So yeah about that weird looking hump around the sump plug. Upon loosening/tightening it when changing the oil last I heard a slight crack however thought nothing of it. Did the oil change and took the car for a spin around the block, all seem fined so I parked it up. Working from home this year due to COVID19 I didn't go outside for 3 days, to then find a pool of oil running from the front of car to the back..

So it looks like someone has stripped out the sump plug thread in the past, and inside of fixing correctly they decided to JB weld a nut in front of it.. I really do question ones mindset whom thought this would be fine. I mean it "worked", but still..

Anyways lets get this sorted. The previous owner so happened to have a spare B16A sump (raises some concerns), looks like it had been left outside as it was covered with leaves, fluff & dirt so used a can of degrease trying to clean it out. Also ordered a brand new OE sump gasket. Also went ahead and left the sump bolts/nuts in some degreaser to clean them up a bit.

After:

And here is the final product, much better. With this out the way I think the rest of the car mechanically seems quite good. The bottom of the gearbox looks a little wet, will need to look into that in the future however it's a very slow leak.

Also when dropping the lower part of the exhaust to remove the sump, I noticed 2 of 3 nuts on the flange were well backed off.. Look forward to finding more dodgy stuff on the car.
