Well this was a dramatic saturday.
Sat waiting for a friend with the engine on idle, and all of a sudden a rough running noise and plumes of white smoke.
Get my dad to come and tow me home, try to show him the smoke, and it won't do it. Leave it running for a while and it reproduces the fault. It runs as normal as ever when not smoking.
There was a suggestion that I had misfuelled the car, although this has been eliminated.
The AA man came out to check while we thought it was a misfuel and fairly immediately diagnosed it as injector seals.
Last night I pulled all the covers off, and it's definitely fuel damp around injector number 2.
I'm not entirely convinced that just the seals would give this volume (plumes) of thick white smoke, although it definitely smells like burning diesel. The smoke eminates from around the exhaust manifold/turbo below the airbox, but it's a real pig to see down there where it is coming from.
I have a couple of questions, assuming the AA man is right and it is just injector seals, would the guide for the M57 be pretty close? It certainly looks very similar to the top of my engine. I do most work on my car myself, although I was worried about the high pressure fuel line holding pressure when the engine is off.
Does anyone have any suggestions about the actual cause of the fault, or replacing the injector seals? A quick look on realOEM shows a copper washer seal and a rubber O ring. I guess do both with the effort I am going to. Only £10 for a full set of both seals, despite most garages wanting best part of £200 to replace them.
Hope you and your cars are all well
