Dripping tin top sump plug

Just changed the oil in the tin top and noticed that the old washer had a slight weep.
So I fitted a new copper washer and filled with fresh oil.
But can I buggery stop the the drain plug from weeping.

What can I do to stop this. Any techniques.

Brad.

I have thought about that but thought I would end up with bots in oil.
Still worth a try.

You could use a dowty or bonded seal washer which should be better. Sounds like either the sealing face on the sump or the sump plug is pretty poor.

You can get self centering dowty washers which will make the job a bit easier depending on the design of the sump plug.

IIRC you have a pressed steel sump on that vehicle, and the threaded insert in the pan has 4 cutouts where it's attached which when used with a plain copper washer do not seal.

This design requires a deformable copper/fibre washer like a renault or peugeot used to use and change it every time it's removed, a dowty washer does not meet the face of the standard bolt correctly but if you can find a m14x1.5 bolt to match with a wider flange then you can use a dowty washer and reuse multiple times.

Stopped it dripping using the old washer.
Thanks for the help. Will get some proper washers ordered for next time.
