Saint, yes one of the things my mechanic did say was that you can manually fix the inlet vanes/valves to open all the time. Not the most efficient but does stop wear and leaks. I should have also said that the four little black round bits of plastic on the inlet manifold (that the linkage connects too) are all loose and leaking.
Got it back today, three injectors and a glow plug relay. They only billed me for 2.5 hours rather than the 8 it had taken because they were very disappointed that the car is only slightly better at starting now. They'd also changed a sidelight bulb and changed the notoriously difficult to change air filter for me. Still cost me £729 but could have been a lot worse so big thanks to Alfasport.
Where are wenow? Fuel pressure is low when cranking and drops off after a you give it a big blip on the throttle. This is symptomatic of high pressure fuel pump failing. Somebody did mention that a while ago so well done, top marks. To change the fuel pump which in itself is not too expensive you have to remove the cam belt. That as you know is a £250 job on it's own.
He did say that I could kill a few birds with one stone. Changing the inlet manifold means cam belt off. If the cambelt is off I might as well change the fuel pump. Then he mentioned,,, "but the turbo vanes are definately stuck open". Very little low rev grunt and then a launch at around 2500rpm is evidently indicative of the vanes being stuck open causing slow spool up but then over boost at higher rpms.
In conclusion,,,,,,,,,,,,,, it's f**ked but to the untrained ear it runs fine. It does start a little better now so I will be running the remaining bio' in the tank through it and then trying regular diesel. If it's a starter and a runner on regular diesel I will then be doing the rounds of the dealers.
What the hell, it's only money. Now where is the button on my keyboard for floods of tears??????
