Looks like a new car.

Very smart.

Being tired of guessing how much fuel I had, I bit thebullet and dropped the fuel tank. Earthing the feed prior to this had shown that the gauge was working, and so it had to be the sender.
I syphoned the tank dry and tipped most of it into the other cars, then undid the four bolts and dropped it down.
The old sender had a detached (snapped) connector between the coil and the outside terminal. It could possibly have been repaired, but I had already got hold of a new one, and so swapped them and put it all back.
Tipping five litres in showed no appreciable movement of the needle, but it did at least show some signs of life when the ignition was switched on.
I drove to ASDA and filled her up. I was pleased to see the needle swing across to full.
Excellent.
I can live without the oil light, I always check the oil on all my classics prior to taking them out and I am not particularly keen to start taking off the front wing and disconnecting electrics, in order to replace the sender, or reconnect the wire. Maybe next summer!!!

Being locked down, I have now started to work through my three cars doing the jobs that I had been ignoring, starting with that 2CV oil light.
Alas the Citroen hasn't had many outings this year. It was stashed away in my daughter's garage over Christmas to get it out of the way, and didn't appear then for quite a few weeks, to be grounded again by the various storms.
Well, anyway, I have dismantled the front of the car to replace the pesky oil pressure sender (front wing removal required).
There is also a fairly prodigious oil leak that only manifested itself when I backed the car out of the garage the other day, and left the engine running for a few minutes.
This appears to be caused by excess crankcase pressure which is caused either by:
a/ A knackered engine.
b/ The failuire of the engine crankcase breather system.
The engine starts and runs well and so I am inclined to replace the breather/filler assembly. This incorporates a dump valve that allows any oil mist that is forced out of the crankcase to drain back into the sump, and ingeniously (it is said) creates a negative pressure within the crank case so that it sucks air in rather than squirts oil out.
The general view amongst those who know is that the assembly can need replacement every five years or so, so now, after some finger crushing acrobatics, I have the new assembly in place.
All I need now is a new fanbelt, the one that Ihave carried around as a spare since last summer which claims to be the real thing, is actually a good 50mm longer than the original, so I am waiting for a smaller item to arrive and the Deux Chevaux therefore sits with its fan and mesh grille removed, awaiting the part.
Not that anything is spoiling, the weather is cracking but we are, as they say, grounded!.
