Title: Oil drain plug
Post by: cbudden on 24 January, 2025, 06:29:57 PM

Good evening, Could anyone advise me of the dimensions of, or better still, a supplier, for the oil drain plug on the underside of the crankcase. I have measured the hole with cheap digital calipers and I don’t arrive at a sensible number in metric or imperial! Any help gratefully received.

I probably have a spare, I will look over the weekend. If no spare I can certainly measure it for you.
Regards
Mike

That would be great, many thanks. I spent a good while on the internet trying to find something but to no avail. I am just about to start rebuilding an engine I bought as several boxes of bits and have just had repairs to the block and head done. It’s all new to me but interesting!

Hello Chris,
The tread is M30 X 1,5.  the Hex for the tool is 22 mm. Instead of a copper gasket, I use an O-ring as seal.

Thanks both, very helpful. In case you are wondering I recently bought a project 1935 factory cabriolet (type 34). So expect to hear more from me!!

We are wondering! It would be much appeciated if you can tell us the story of your Augusta project, perhaps a few pictures. Thanks very much.
