Grey goo is the official stuff for the job... it's a different compound to the black goo used at the top of the engine.

Obviously use what you will, but be mindful of the fact that it will require adhesive properties as much as sealant ones  ;)

....
Also - can you be sure it'll withstand the temperatures inside an engine, and not break up and clog the oil pickup strainer? (for consequences, see above) ::)

I've pictures of the silicon sealant I retrieved from the oil pick up strainer of my Smart Roadster. I'd buy & use the proper stuff, it goes off properly.  :y

I thought that proper liquid gasket goo type stuff like Hylomar dosn't actually set hard, but stays flexible to cope with expansion/contraction, vibration etc  :-\

This sump (08) is not the same as the 04 sump I removed recently. How do I unplug the above lead (blue lever?) to the oil level sensor?

IIRC the blue bit is like a wedge that pulls out then you can squeeze the tab to release

Thanks. Entwood post 19oct18 'Engine Sump', last post TB 7Nov18; GM12388521 $12.50 from USA, or 12.50 free P&P from christopherjohn007 in Manchester; comes in a 5.3 ounce pot. Looks like a life time supply and I was expecting something in a tube like the black cam cover goo, but it sounds good stuff, mends head gaskets, leaky fuel tanks, etc.

The black stuff sets similar to the kind of stuff you'd put round your bath/shower. The grey sets harder but not solid.

Thanks Dave, it did not work. Here are some more pics. From below, you can see the drain plug dripping.

Plug from alongside

Plug from a little above

In the last pic, should the blue wedge go left and down, right and up, or right and down?
I made a similar error on the dead Astra removing a plug below and in fornt of the battery. I managed to pull out a yellow clip, pulled oit too far and broke it. Half way out the plug was free to pull off.

This 08 Astra has not the same sump as the 04 Astra I removed last week, more screws and different oil level plug. I wish they wouldn't change things.

Wrong, same number of screws. Sump is now free, suspended by the oil level cable. New pic follows. How do I disconnect it?

In that last pic ,there is a tab above the blue wedge, it has 4 ridges
push it towards the sump
if enough of the blue wedge is out the way  :-\ the plug will slide off left

if you look at the pic of the new sensor,
you can see the nib (top left on electrical pic) that the plug is retained by
