Here is what the `Citroen manual shows and says. Parts 3 are the seven rubber O rings i mentioned. Regardless of what the Brooklands/ Haynes type manual shows, note that there is no ‘o’ ring under the smaller front leg to the left in the photo. And, also note that the instructions below are to NOT fit an ‘O’ ring on the ‘front screw’ (i.e. the bolt for that front leg).
So no – any metal washer you found isn’t the part shown in some diagrams.
‘Turing over’: you mean you are moving the head around on a bench so that you can see top side and then underside and some bits have dropped out from somewhere?
The cylinder head has channels for oil, coolant and fuel/ air. Easiest ways for a foreign body to get into / onto the head are through the oil filler funnel or dropped down the carb into the intake manifold.
Looking on some parts diagram, I noted that there is a “washer” under the block that supports the front oil supply end of the rocker shaft
Do you mean diagrams like this one that show a single ‘part 28’?
If so, the English translation in the parts catalogues is ‘ring seal’ (‘O’ ring) and it’s not a single part. There are seven of them under the legs that support the rocker shaft. They seal the oil channels up through the legs and into the rocker shaft. They are made of rubber but get compressed and harden over time making them difficult to spot and also sometimes remove.
EDIT: I think I’ve found the diagram you mean in a ‘Brooklands’ type Haynes manual thing, where it’s labelled as a part 17 and is under the part labelled as ’20’ in the image i’m posting here – though a ‘washer’ or ‘ring seal’ is not shown. I’d need to look at some rocker parts to see if that end leg is recessed for an ‘o’ ring.
What size is your washer/ is it for an M7 bolt? Larger? Smaller? Is it thick? thin? Not an M10 washer from an exhaust side cylinder head bolt is it?
Check valve and spring. You’d need attach photos if you’d like help identifying them.
Hi. That damaged pipe is the feed of high pressure fluid from the pump to the accumulator – which it why it’s a fatter pipe. Cupronickel pipe is fine for use as 4.5mm pipe but not really strong enough for 6.35mm applications. And the pipe really needs to have Citroen flares.
Regulator position. EFI cars had them down the front of the gearbox – though not in the same position as yours – and lots of people move the accumulator/ regulator to on of the chassis legs. It’s probably been moved to give easier access for changing the sphere, but how often does one need to do that? Having said that…..if you’re uncertain of the age of your accumulator sphere and are feeling flush, then now seems like as good a time to change it as any. And yours will be a damn sight easier to get at than mine is.
Depending on the cost, you might consider getting two pipes from Darrin. Firstly just in case your bending goes wrong but if all goes well (and I really hope it does), at the very least you’ll have a spare to carry. How will you measure the length of the old pipe? Might be better to have any new one a little longer rather than find it’s too short – but you can see it’s routing so know whether that is a risk or not.
Now would also be an ideal time to re-route that pipe – something with coils to reduce stress and vibration. here’s an idea.
But if you need to rely on Darrin to make the pipe for you, you don’t have the luxury of being able to experiment and choose a different route. Maybe you could experiment with your dead pipe and then get something made up??
When you remove your dead pipe, make sure you look carefully in the threaded holes on the accumulator and pump as you will almost inevitably need to pick out bits of shredded rubber that would otherwise block your system.
Hi
I know the pipe you mean. On a RHD ID car, there is a 6.35mm return pipe/ hose coming from the brake valve. That is certainly true of the aluminium brake valves, and so it’s tempting to suggest that the pipe you are referring to is a continuation of that return pipe. BUT i think later valves were made of steel and a different design – so may not necessarily have a 6.35mm pipe.Also, because of the reduced room in the RH footwell, there are some odd combinations of ID and DS brake system components. After 1970, RHD ID cars had the ID braking system but a brake mushroom. So I’m guessing a RHD Ds would have a mushroom, but the DS brake system? i suppose i’m only repeating what you are already concluding.
What’s behind your question? uncertain as to what part to buy/ source? Mismatched halves? Can you trace the relevant pipe from right to left and see where it ends up – to determine its function? In addition to the one here,’ve got a few more photos that might help??
