basicly my mini sump plug thred is slighty damaged and will not nip up tight. iim looking to re tape the thred on it and replace with anouther magnetic sump plug i think the size is 5/16 or 24mm what size plug would say is my best bet

helicoil it, its the only proper solution imo

Helicoil is the way forward, there are taped sump plugs but I'm not a fan.

There seem to be a flurry of sump plug problems at the moment.

 

See the thread linked below for additional information.

Over tightening usually due to coarse thread

 

I had one years ago, 1966 998 Cooper and the threads came out with the plug, no money, little engineering skills or facilities being a young teenager at the time.

I cleaned the area with paraffin, washed off and allowed to dry, I then stuck the plug back in and used fibreglass filler all around it and allowed to dry.

I then filled up with oil and it didn't leak. Next oil change I chipped it all off, drained the oil and fibre glassed it up again.

 

Now I am not recommending this as a solution to the problem as it is a bodge but it did for me at the time

A helicoil is the ONLY correct way to repair a damaged sump plug thread. 

 

There are lots of threads regarding helicoils, do a search
