I'm about next weekend, so should be able to do it if you get the bits. Sadly no where out of the rain to work - well, that's not strictly true - I do have a large garage, but it's rather occupied with the Visa and assorted building and baby (-expletive removed-)!!
In fact that happened to me just the other day when I was refitting the heat shield correctly, only my feet sticking out the side got wet. Ok that sounds reassuring. I hate tackling a job of unknown requirements without being well prepared but it sounds like we would be well prepared for most eventualities. As I said I ordered two sets of clamps just in case some experimentation is required and we need to try plan B. My main worry is that the sleeve may not be able to slide fully over the cat tail at all, (only push onto the end) as the picture shows a reduced diameter between the main part of the sleeve and the chalice/cup...so we may not be able to mimmic the original fitting but have to devise something slightly different.If the length is about right you might just be able to slide on the repair piece and clamp it up - which will avoid the need to remove the CAT - it will need to come off for sure to weld it, as we'll need to grind off the old weld bead and then put a ring all the way around. Should be able to weld the other part onto the silencer as well no problems. getting the Cat off can't be worse than an HDi....can it???? I've got a good selection of wobble bars and deep sockets to help. Even if the repair piece is not the right diameter, the angle grinder will make short work of putting a slot in it to shrink or enlarge it as required.
Will do Richard, I was planning to bring it anyway just in case you might have anything that needed a Lexia session.You can bring your Lexia and stick it on the C4 Picasso - I'm interested to know if the evaporator temperature sensor is working....!
Me too... you can read about the tribulations I had with the HDi exahust Here Still holding 2.5 years / 40k later thoughCitroJim wrote:Most engineers hate exhaust work. I do certainly.

Looks like the fittings have arrived, (waiting at the post office) PM sent about Saturday
I await to hear good news Simon! It was great to meet another FCF regular to put a face to the name. 
The "leak" appeared to be from the expansion bottle but with no obvious source of the leak. I later realised the problem - I'd (stupidly) topped the coolant up to the brim the previous night when the temperature was close to zero and the engine was near cold, so on the 20 mile trip to Richards it had obviously heated up and expanded to the point where it was forced to vent excess coolant through the overflow valve. 
The minimum and maximum marks described in the owners manual seem to be missing - we both looked and couldn't find them. Should I top it up to just above the pipe visible in the bottle when cold ? That seems to be where it settled after expelling the excess. I assume the HP20 doesn't have a cover that is removable in place on the car to access the filter like that Porche gearbox ? Shame if it doesn't, I'll have to hope that a change or two of oil will do the trick...
sounds rather like the diff making a bid for freedom, although I'm sure it isn't - and the 'box deffo doesn't appear to be doing what it should at times. Well the only thing we actually used from the kit was one of the conventional u-bolt clamps.CitroJim wrote:Excellent stuff Simon, delighted the kit worked to make a good exhaust repair. That saved a good cat and a fortune at the same time
I'll keep the rest of the kit in case I have any further problems. I did check the flare of the fittings to see if they match the flare of the end of the silencer - which it does seem to, and the inner diameter is a perfect snug fit for the end of the cat tail, however because there is a reduced diameter section between the end and the flare its impossible to slide it over the cat tail completely to reach the original weld line, hence going for a different approach which also saved trying to remove the cat from the car!
Ok, must remember that. I plead temporary insanity, I should know better than to fill up the expansion bottle to the brim when cold!On the coolant level, I always maintain mine so that when cold the coolant is just lapping at the edge of the round tube you can see in the tank. That I'd say was about 2/3rds full...
It certainly gave me a scare when I arrived with coolant leaking all over the ground. 
(I bet Richard wasn't too chuffed either )
I managed to contact Stempy by PM last night to see what his recollections of his gearbox problem cure was, he had this to say: (I hope he doesn't mind me reposting it here)That's an interesting article on the gearbox indeed. It'll be a good idea to swap the oil as soon as you can but sadly, on the HP20 the filter is inaccessible unless you strip the gearbox. There is no other access and I've looked very carefully to see if there is but sadly it's an engine out job and a gearbox strip. If you go that far you'd be well advised to drop the torque converter off at Mackie's for a rebuild as well.
That's both very encouraging and also a bit worrying. Encouraging that when he fixed the problem it went from 56k miles to 120k miles with no further problems. Worrying that he had problems as early as 56k, and that he found a leak that needed fixing since low oil is so deadly to an autobox.Stempy wrote: As I remember the problem I had was caused by low oil level caused by a leak from the oil return banjo union on the side of the gearbox. After I fixed the leak and replaced the oil the problem did not return and the gearbox was fine up to the 120 odd thousand miles it had done when I parted with it.
I hope its not low on oil, I really should have checked it weeks ago but I wasn't sure whether I was chasing an engine problem or gearbox or both at the time...Yep that's how I did my HP14 - front of the car up on ramps, drain the oil, put the plug back in, roll the car back down onto the ground without starting it, then top it up. So you think I should get a minimum of 5-6 litres ?When you drain you'll get about 4.5 litres out if you really try. I find it best to raise the front high on stands and let the rear drop as low as possible and then the drain plug is at the lowest point. I'd be tempted to do two changes in relatively quick succession.
I think I'll do that. A 20 litre drum (which would allow 3-4 changes I guess) is rather pricey when I don't know if it will cure the problem, and could take a bit of time and trouble to source. I have a Citroen dealer a mile down the road that I've got parts from a few times now, so I think I'll just phone them on monday and see if they can get me 5-6 litres ASAP.Best place to get LT71141 easily is from a Citroen dealer. It's available under part no. 9736.22. Else that, if you plan on more than one change then go for 20 litres of the stuff from one of the wholesalers.

Jim you're a starCitroJim wrote:Simon, a source of LT71141: Opie Oils
Do you think I need 6 litres or will 5 be enough for one change with a bit left over ? (I'm watching the ££ until I'm paid )
