OK, fair enough.  Didn't want you thinking I was being intentionally or unintentionally rude or British humour.  I have E5 but lots more experience.  😁

 

Bad news...

 

I suspected from another source of leak and finally found this:

Now please if anyone knows, what is this mysterious recess?

 

This picture above is from my engine. I used a mirror to take the picture so it's inverted. The mysterious recess is well hidden from eyesight. It's just below the bolt I've asked before. I couldn't notice this before because it was covered in oily muck.

 

It's angled downwards. I'm afraid it might be some kind of over pressure relief plug. If that's so, I think it's impossible to fix it without removing the engine?

 

I can't imagine removing the engine because of this.

I've found something about it.

It's number 32.

It's an 8mm plug. Like a freeze plug but installed on an oil channel. N90796301

Now, how would you replace an 8mm plug on an oil channel without removing the engine?

No, it's a metal cap. Like these:

 

But very small diameter. Only 8mm.

Washer Cap Push Nuts or

or a guy with lathe machine to make you one.

Yes it's an oil gallery machining port. 

I would advise to either find a freeze plug or tap it and install a SHORT BOLT

You could always try ebay https://www.ebay.com/itm/333634438489?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=j904vylftb6&sssrc=2349624&ssuid=Wvh0A9psSSW&var=542731153057&widget_ver=artemis&media=COPY

Shouldn't I worry about metal dust inside?

 

Great ideas by the way. I'm glad you are active again. I missed your posts.
