Do you mean the coolant expansion tank Scott?

After removing its two mounting nuts it should not be stuck at all... It should then be easy to pull it forward from the bulkhead... The coolant pipes can get well stuck on its spigots but you should not need to disturb them to fix the dosuer return pipes...

It's not fragile from a handling point of view so you are at no risk of breaking it in doing the leaky return lines but they are well known to leak at the central seam under coolant pressure...

One thing to note if re-routing LHM return lines, is that where a component appears to have 2 low pressure return lines, one of them is usually actually a vent line to let the component "breathe" and in some cases (such as the rear strut gaiters, air from the vent line is used to push lhm in the return line uphill to the reservoir.

I agree that the coolant expansion tank is not fragile, but the hose at the bottom can be stubborn to remove.

The degassing tank (mounted on the engine below the expansion tank) is fragile and unless replaced recently will shatter if you look at it. For a few years they were very hard to obtain, but I think that they are being remanufactured now.

Do you mean the coolant expansion tank Scott: yep thats the one, I'm guessing that it must just be because its old and not been worked on in a long time thats causing it to be like that,ill have a another crack at it today, now that i know that its not so delicate that will help a lot, and will be one step closer :-D
thanks Jim

its nice to see that the is a aftermarket market ,so to speak, these are such nice cars so I'm glad its still possible to keep them going, but i bet the prices must be scary, id assume, just because of the smaller scale of production.
Thanks v6

hi everyone, its been a nice day doing some work on the car today and i thought id let you guys know how its getting on. I've found to finally what the culprit was for the leak,and I've almost finished the repair. it turns out this bottom return line was the culprit and had split in many paces on the under side. to create the repair section i learnt the skill of silver soldering and i made this and this is it after a little neatning up as it went from a 0,6 id hose to a 0.5 od hose .and putting it all together it looks like this https://imgur.com/UDGGDz1. now all I've got to do is put it all together with jubilee clips and re connect the hydraulic lines.
i hope your all having a good day in the sun shine and ill speak to you soon :-D .

You might not want to use jubilee clips, as they do not make a round seal. There are more suitable clips available (although I do not know which they are), mentioned on the forum in several threads.

They look fine Scott... Just peel off any bits of loose rubber that have been caught in the threads and reverse them so the 'clean' ends are on the front of the pipe and the ends with the thread indentations are up against the pipe flare ;)

hey Jim I'm just getting annoyed with this car, I've been trying for the last two days to to re attach the hydraulic pipes into the doseur but only one will go in. I've tried placing the seals on the ends on the pipes, putting the seals in the holes where the pipe goes in, and I've got the union literally touching the doseure but it just wont screw in no matter how hard i try, i was wondering if i had to re thread the threads. But i just dont know, and i thought it best to ask you to see if you had any tips
thanks Scott

Tricky one to call without seeing them but if the 2 pipes have the same thread test fit them on the other threads - that will tell you if the threads are good or not :?:

I have had trouble before with a pipe I had made up where the joint wouldn't do up and I resolved by trimming the length of the rubber seals to allow the threads to get that initial bite .....

Where in the 'grim North' are you :?: Maybe someone local would be able to pop around soon ......

Sometimes what can be character building is knowing when to ask for help. A fresh perspective on a problem can sometimes find something that has been missed.
