This is because the idiot doing the service for reasons utterly unknown decided to refit the rather dog eared copper washer rather than replacing it. Which would have required him to walk all of four feet to pull one out the box.
This has now been rectified.

On the plus side, the sump only holds 1.75 litres of oil so I haven't wasted much by changing it twice in 200 miles.
On the downside, the sump only holds 1.75 litres of oil, so you *really* want it to stay inside the engine.
While I'd got the sump empty (again) I figured it wouldn't hurt to take a look at the sump strainer. I had been checking it religiously for the first few oil changes as quite a bit of sludge was initially washed out - but subsequent checks revealed nothing so I'd left it be for a while. Reckon it's probably been untouched for 650 miles or so now. Any slime present today?

Nope. Clean as a whistle (well, a very oily whistle...but you get the idea). The grainy looking bits at the far edge are attached to the gasket. No deposits in the basket at all.
I think with regular oil changes and the sort of driving I do I can probably drop pulling this out down the service interval list a bit. It's worth keeping an eye on, but definitely doesn't need to be pulled out with every oil change or anything like that from the looks of things.
Later in the afternoon I found five minutes to fit the new horn properly.

Aside from needing to fit the proper foam pads in the fuel tank frame (which I do now have in stock at long last) it's *almost* looking vaguely orderly under here now...

The spare belt got in the way of the catch for the hatch so has been relocated to in a bag under the seat for now. I'm probably going to attach a couple of the down points for said bag on the fuel tank supports when I have them out to fit the anti vibration pads so it can stay up front, but somewhere actually out of the way.
I took the Jag out for a quick run to the post office in the afternoon and it rewarded me in a typically Jaguar way by having random components decide to fall off for no readily explicable reason.

Situation normal then!
