Jon W Posted December 19, 2007 Share Posted December 19, 2007 This has been occuring for a while but thought it was blocked injectors due to dodgy fuel/SVO in winter temperatures and the fuel filter needed changing a few times. However problems have persisted whilst on pure diesel. After draining the tank etc and injector cleaner being used. Symptoms: Starting on 2 or 3 cylinders and will on run on 4 and turbo spools up once 200yards up the road. This gives whitey blue smoke. When it is warmed up it runs fine but when on light throttle or lifting off with a very slight bit of throttle it puffs out the same whitey blue smoke for a little bit and feels like it is a cylinder down. It is not using engine oil. Isn't doing very good mpg at the moment. But having spoken to someone recently they think that it probably isn't injectors as these would drop fuel in with a bad spray pattern and it would be black smoke if it wasn't burning properly. So they think it is due to an air leak in the inlet system or the vacum system. Where about would one start searching for an air leak and is this the right diagnosis?? It could be the vacum as the brake pedal doesn't really drop when you start the engine when hot or cold, sugguesting the vacum on the brakes is suspect. Any help on anything to check is much appreciated. Thanks Jon Quote Link to comment Share on other sites More sharing options...
