Hello Mike, sorry about the delay, I was waiting for Vauxhall service to phone back.
I purchased the vehicle privately in July 09 with this smoking problem, it still has 68000 mls. I know nothing about the first 3 years service history but the guy I bought it from in Deal, Kent, bought the van himself, the previous year around july 08, off the company he was leaving.
He only had the timing belt changed - although when I checked it, I found the pump timing slightly out of sync to the Crank & Cam therefore I changed the belt again and retimed it using the 8mm & 6mm locking bolts.
Yes, the Vauxhall Agent in Crawley West Sussex has just phoned me back and confirmed that Tech 2 diagnostics equipment was used although nothing was found a miss.
The advice was to remove the manifold and free off the inlet flap and secondly, check the engine timing.
I haven't changed any sensors only disconnected them.
Acting on advice from Auto Marine Diesels, I have also removed the cat, as in their opinion it doesn't do anything drastic to these emissions but it could be blocked or restricting the flow
As for the opacity when tested - the lowest value registered on the machine was 6 and unless I'm mistaken, the pass is much lower at 3.
With all the sensors reconnected, the smoke is horrendous and they refused to test for fear of clogging the machine.
I think that covers everything and hope my problem can be resolved without any more major expense.

Kind Rgds, MIKE
Feedback and any Bonuses are always appreciated too. Thank you.
I have set aside the money which you will definitely get but I'm new to this site. I'd like to go and try things and perhaps ask a few more questions, then of course I'll accept.
Is this agreeable?

Hi, I am a Car/ vehicle mechanic of some 32 years. 25of -running my own repair/diagnostic business.
Oh I see, well in that case I can pay now and you can let me know when my credit runs out! Many thanks so far Mike, I'll be in touch.
Hello again Mike, Changed ECT Sensor - £15 @ Vaux., ---- just the same symptoms though, all sensors reconnected, tons of smoke, disconnected, much much reduced but still too much to pass Mot.
However, I will continue with your other excellent suggestions.
ps. Correct me if I'm wrong - If the high pressure pump is used to fill and obviously pressurise, the common rail, prior to the ECU firing the injectors, why is the timing of the pump deemed so crucial to the operation?
