Sump plug drip

[kervinmervin]

Since the last oil change, the sump plug weeps a little (single drip when stopped) - mainly when warm and after being driven it doesn’t seem to have a massive noticeable effect on the overall level. It probably happens now as I’ve taken the guidance and nip it up to 25N rather than just tightening by hand, previously I would of tightened a touch more to stop it. With a fear of stripping the threads i’m inclined to just live with the small amount that leaks or should i nip up more?

Copper washer replaced each change.

I'm not sure - its quite a large thread, I realised this when trying to find standard washers - but not sure, I took a picture last change to try to investigate more, do you think its just tapped to a wider diameter?

Use 10 windings of PTFE tape on the plug thread
