Thread: Blue/Grey smoke from 200tdi defender

If the timing had progressed, we'd have tested the Big Bang theory by now... I was hinting that it could have been fitted 1 tooth out on the cam or pump. Just an option. The older Turbo D 2.5 will run happily with the pump one tooth out but are pigs to start and smoke exactly as yours does but worse until warm. (Good clear vid by the way). If its not using any oil, I'd still be sticking by my injector suggestion. Glow plug failure usually make it smoke white on initial start up with misfire (white smoke=un burnt fuel), but being direct injection the Tdi usually clears instantly. Yours still sounds crisp on start up tho which is good. Nomad9 mentioned replacing injectors.. If the spray pattern is not 100%, or if the internal injector springs become weak, the injector will drip. This means that during combustion, each cylinder will still burn all the correctly atomised diesel, but the 'drip' of fuel will only be partially burnt giving white/light blue smoke. Oil being burnt is usually a thicker white smoke with a different smell. It'll also hang in the air longer. If you go on a decent journey and get the engine to working temp, then return to the vehicle 10 min or so later and restart it does it do the same or is it just one black puff then clear? Cheers!

Sitec, The last time I drove her (Friday) the smoke was as you saw, then not long into the drive, the smoke cleared and I only saw the usual black when under load climbing a hill or leaving an intersection with a bit more power on. After driving for a good while, I parked at shop, did what needed to be done and about fifteen minutes later, came out and looking around to make sure no one was around, started her up only to see the usual black puff and nothing else......

She's up on stands now to figure out what's going on at the left rear brake caliper. 'Surprisingly' a leak has developed so I'd best figure out what's what....

Cheers

So one issue is being rectified (left rear hub seal) and the Tuesday after Easter, Nigel is going in to United to have her injectors and injector pump tested and checked out.
My engine was rebuilt in 2009 and in talking with Steve in Morley, he's confident that the valve stems should be okay.

So, there won't be an update from me until early April - I'll post the outcomes of the test when I get them.

Regards
