Hi and hope you all had a good Easter.just bought a 307 1.6hdi for my sins as my beloved 2.0 hdi the flywheel has disintegrated.however on this 1.6 hdi I have a shaky rough engine on idle and blue smoke and the fumes are really strong they hurt your eyes and smell like a tractor!when it's warm it clears up slightly.whwn driving at low revs in 1st gear the engine seems to hesitate??ive read about these engines and diesel injector seals but they all look clean apart from the one closest to the battery as it has what looks like a slight coating of engine oil and the others look orange from rust.does anyone know what this could be?ive got no eml light on or nothing.car seems to be ok but slightly underpowered.any help would be great guys.thanjs in advance.
