Smoky start

On or around Tue, 1 Feb 2005 19:02:48 -0000, "Demon News" enlightened us thusly:

probably diesel smoke, though, from incomplete combustion with a cold engine. 's common enough on old diesels.

I asked the same question about six months ago with respect to my tdi 300. Consensus seemed to be that it is normal and not to worry. Right enough, it doesn't seem to have got any worse or caused any problems, and the (land rover specialist) garage have serviced it a couple of times since and not commented that it was out of the ordinary.

Relax!

Grand! I will ignore it. It seems to tick along nicely anyhow. Thanks

The puff of black smoke from from 200 and 300 Tdi's is due to a brief patch of low pressure in the induction system leading to incomplete combustion, and indeed is normal. The old 2.5 Diesel's dont have this "feature". However, a couple of seconds of "oily" smoke on start up is not uncommon due to hardened valve guide seals, and as such is nothing to worry about either, just keep an eye on.

My initial reaction was the valve stem seals. I will keep an eye on this.

Thanks, Russ

I rebuilt my 2.5 n/a, and it still has a brief smoke when you start it. When it smokes all the time, and you find yourself leaving a smokescreen behind - then its time to start thinking about doing something!

My 110 TD5 smokes noticeable for about 10 miles, until the thermostat reaches its half-way mark. Then it is ok.
