Sump plug removal

Picking up on Andrea's point of engine type/engine number, have you ascertained what engine type you have (potentially) by reading the stamping on the flywheel rear housing near to the starter motor?

I haven't looked specifically - will see what I can see when I am home later, I've got the starter motor out at the moment being rebuilt so hopefully can find the stamping easily.

From the replies it seems there is no standard for the sump plug location!!

It looks like a mix of parts - 818 303 on the flywheel housing but the engine itself is 818 302 so older than should be in the car I think as it's a '72 S2 Sport

303 used 302 castings so I would not be worried. Differences are in piston and valves and cams which are hidden in side.

Thanks, I'm not about to take it apart to have a look - at least, not as long as it runs OK when I do get it started!

I've managed to get the sump plug out today, it was very tight and not helped by the wear inside it. Helped by the tip from Tim in the thread about basic service in terms of putting a jack underneath it, don't think it would have worked without that so many thanks. Really pleased I didn't have to drill it out. The plug also came out of the other sump with the help of an impact driver but I think I need a new washer at least. No rush as I'll leave it to drain for a day or two.

My plan is to change the oil again very soon so will use a thinner 10/40 for the moment to ensure it gets through everywhere unless someone recommends differently. I'll add some flushing agent after a couple of hundred miles and drain it all out again before putting some good quality oil in it.
