Went for my EU inspection today. After an initial failure 
for lack of brake boost I got some help, fitted an old relief-valve piston (with, crucially, a soft, older seal) and the booster came on again. Then we had a pass, and I can legally drive my Rover again for the first time in eighteen months 8) The rebuilt PAS pump gives me slightly better assist (it's pretty light now!), but I've not got rid of the growl that comes when maneuvering. It sounds like it's coming from either the pressurised hose or somehow from the steering box. I'll try to bleed it next.
Changed the oil yesterday, for 20W 50 "classic" type mineral oil from Biltema (not unlike Halford's), made by Statoil and with more than 1000 ppm of zinc. There is a ticky tappet in the engine's RHS bank that's a little more muffled now. I'm leaving that for a 3.9 camshaft modification. I fitted a good brake pad for the one that was contaminated (thanks mrtask!) and set up the rear calipers again. I've tidied up the wiring to the electric fuel pump using crimp-on bullets with a bit of shrink hose and original Lucar connectors. Found two unused wires, one green/purple by the inner LHS headlamp, which must be the fog pickup, and a green/black of unknown origin. I can so far not spot it in the diagrams.
Oh, I almost forgot - the brakes guy, who knows the P6 well, shakes his head at the rear bleed nipple sitting below the fluid line port. You "never" get the air out of them as long as that's not changed around, he says. And he also shared a tip for bleeding the system, which is probably tandem-circuit specific... The union next to the booster has a pressure failure warning switch in it. This must come out and the moving thingy inside jammed using a pin before bleeding commences. Else one system will bleed but the other block. Which explains why we couldn't bleed the rears at all with either of the fronts having been done first. I'll let him sort my next fluid change. End of story.
