The next stage in my TD4 saga (manual, 118k, 2003 52 plate) !
After eventually getting it started after a clutch change, I've been keeping myself amused fixing the window regulators. Now they are all sorted, I started it up again and noticed it smokes. There's a bit of bluey/grey smoke on startup which I kind of expected at 118k miles. But what I wasn't expecting was clouds of grey smoke when revving it. It seems worse if I hold it at a constant throttle for a while - clouds of grey smoke. But if I let it idle for a few minutes the smoke dies down and then stops, but it comes back again if I rev it.
It does not smell like oily smoke like from a knackered petrol engine, which makes me think its probably fuel related ? But its not clouds of black smoke like an over fueling diesel. When revved its mid/dark grey.
When I replaced the clutch I also replaced the crank case breather with the vortex type, I also painstaking cleaned the inside of the inlet manifold and fitted an EGR delete kit. It also had an oil change and a new airfilter. When it was apart I checked all the hoses and have replaced the two intercooler hoses at the front of the engine.
I've run the live data on my diagnostic tool and the only "strange" reading I'm getting is the fuel compensation number for cylinder 2 - at idle, the others are around 6 to 8. but cyl 2 is at 18 to 19. I've previously done a leak back test and it indicated no leaks.
Prior to me buying the car it had been laid up for about 6 - 8 months because of the clutch. I would not have thought the diesel would have gone off in that time ?
The only other thing I've read that got me thinking was a thread about unburnt diesel in the exhaust ? I messed around for ages trying to get it to start after the clutch change (it was a cam sensor) so would it have chucked fuel into the exhaust ?
I took it for a short drive this afternoon and it seems to go fairly well (short private road, so couldn't do much with it) - definitely not gutless or lagging.
Any advice on how to diagnose this would be most appreciated - I can't see it passing its MOT like this !
