Hi this is my first post so here goes.
I have a vectra c sri 150 estate on a 55 plate. Recently my car started chucking out smoke when the engine was warm. But as soon as id turn the engine off and on again it would be fine for another 5 mins or so and then start doing it again. The fuel consumption would drop to 10 miles per galon which was costing me a fortune as it is a taxi. I went down to a dealer and they advised me the problem was my inlet manifold. So i got a new inlet manifold and actuator switch. But the problem was still there. Cleaned out the egr valve but still smoking. So i ended up buying a new turbo from the dealers but still smoking. So a friend that used to work for vauxhall advised me that it may be an injector thats spraying too much fuel which is causing it to smoke. So he tried taking out the injectors but they were seized. He had to use a slide hammer to get them out. Eventually out they came. I took them to a diesel injection company for them all to be reconditioned. Now ive got them back and thought my problem would be solved the injectors are not sitting correctly. They are leaking diesel. He bought some thicker copper washers to go at the bottom to see if this would rectify the problem but it hasnt. Please can anyone help me with some information or if someone has been through the same problem with some advise. I've spent a total of £2000+ on it so far and the car is still off road. (Bad news for me as im self employed and havn't worked for like a month).
Thankyou in advance guys!
