intermittent blue smoke

[rec]

hi guys

ok as title really, have just had 3 of 4 injectors refurbed as 2 were totally knackered and one was fudged when they were tested.

3 were refurbed and all were refitted.
car runs so much better, power is restored nice and quiet etc etc.

problem is its intermittently smoking blue, it has no pattern to it, seems to be after around 20 mins of constant driving, it will just start smoking out the exhaust, the strange thing is if i turn the ignition off then back on it stops?!??!?

anyon know what this could be? car was recently serviced, new glow plugs, new filters, oil, and has just had the injectors sorted. only run it on shell diesel.

thanks

Blue:

Blue smoke indicates burning oil (this is the most common). If the car is older, or has high mileage, than most likely the piston rings have worn down and oil is getting by the piston as it moves down the cylinder wall. It then gets burned with the fuel, which produces the blue smoke. The faster you go, the more smoke pours out of the car. If this is what's happening, keep an eye on your oil level. You will definately have to add some between oil changes. This would be very expensive to fix, so I would recommend continue driving the car and adding oil, but start saving up for a new one.

thanks for the reply. Would that still apply to me though? As its only sometimes and turning the engine off and back on stops it?

guys, could this be linked to the DPF?

or could it be linked to the 3rd injector wiring?

or could it be that it has too much oil in?

Have a look at my thread "CDTi 150 Swirl Bar"

Also, give the EGR a clean too. Unburnt diesel cal produce blue smoke too, as diesel is an oily fuel
