I have just has a strange talk with my local Pug garage who have said that a problem I have with my car looks like it needs a new injector seal which will cost £450 "if it goes well" of a new cylinder head if it doesnt. What do they mean by if it goes well?

What do they mean by if it goes well? I don`t know how the seals are fitted but it sounds as though they think its possible the threads in the head may be damaged.

They havent seen it yet, and it isnt making much noise except for thetss tss of the injector (or the air escaping). It still runs fine (all though we havent used it much) but it has cut out once. The pug dealers havent seen it or even heard it yet. Would we not notice any deteriation in performance or sound if something as important as the cylinder head was ruined?

What model do you have? Do you know which engine it has? How old is it and how many miles has it done?
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

I am puzzled,how can an injectors thread get damaged if no ones ever taken them out!
Has your car ever had any new injectors? if the answer is yes then they could well have been overtightened leading to a damaged thread.

Its a 51 plate 806 hdi (110bhp) and it has done 150kplus miles. It has never had the injectors replaced, I am unaware of any enginge work in the past apart from us getting the cam belt etc changed and it serviced. We have had a new gear box and flywheel / clouutch put on it in the last few weeks.

The 8 valve 2l HDi doesn't have a particularly bad reputation for stuck injectors (that's apparently reserved for the 2.2l version) so they might just be playing safe due to its age. The only threads I can think of would be the ones for the clamping bolts. I've not taken mine out (yet!) but I fairly sure the injector itself isn't threaded.
There have been reports of people unsiezing their injectors on 2.2l engines by using Coca Cola. Presumably it's the mild acid, and possibly thermal shock if the engine's hot, that does the trick. I think that this for the actual injector though, not any clamping bolt.
Moving on, if the injector has been leaking for a while (the chuffing or tss-tss noise) then the cylinder head might need maching for the replacement seal if it's been damaged. Perhaps they mean that?

Maybe they mean that but he definately said the threads. The same garage told me the back suspension / axle was dangerous 2 weeks BEFORE it passed its MOT!! They also tried to charge me £480 to fit a new alternator (inc the alt).
The injector isnt blocked or anything by the looks or sound of it, I believe it to be just the seal is broken. It has been popped into a local garage to see what is the matter today.

As suspected it was a perished / broken seal. It cost me £90 to have replaced as peugeot refused to sell one copper seal and would only sell a new injector rack at £140+VAT. We got a ford one and filed it to size.

It's a bit late for you now but copper seals can be easily reused if they're not grooved or broken in half.
They simply need heating up until colours start running over the surface of the copper. If you then let it cool slowly this will leave the copper soft so that it can deform slightly to make a seal. I just use the gas ring in the kitchen while the wife isn't looking...
Incidentally AFAIK there's nothing special about the copper washers and they should be available from an engine reconditioners or motor factors.
