Grey smoke now won't start
Antara 2.2cdti exclusive ss
Monday night I did 200 mile motorway trip without the car missing a beat, Tuesday night I drove 8 miles got a greyish white smoke out of the exhaust and the car juddered to a hault on the roundabout they wouldn't start and developed a horrid knocking noise,
Got it home on a recovery truck, next morning I had a mobile mechanic look at it no fault codes on his computer and he eventually got it started with easy start in the air intake but it was chapping like mad maybe because of the easy start but it was smoking like it was burning oil and just died again, he said I needed a turbo so I went and got one online.
On further research and some input from a marine engineer the turbo is fine and spinning and the shaft has no play at all. I've since had another retired mechanic round to look at it and he had it running for a few minutes he unplugged the egr and it started but still knocking, he recons its the injectors or contaminated fuel or its not getting fuel.
Sounds like timing to me but I'm no mechanic.
I'm lost might have to go into the expensive vauxhall dealers.
Any help much appreciated, Charlie.
