smoking and missing

Hi I have a 200 tdi defender 90. when I start it from cold it misses and smokes like mad, it lasts for about 5 minutes and then runs like a dream with no smoke and doesn't appear to be missing - any ideas??? Cheers

might be a simple thing like a heatplugs gone down

Thanks but already tried that, put new set in this weekend but no joy.

my 150,00mile 1989 90 with a 2.5td (not tdi) does the same thing. fills the street with blue smoke, which dies away after about 5 minutes, so I too would like to know!!!
a neighbour reckoned it might be the valve stem oil seals that are duff, so they let oil into the cylinders the engine is stopped, and the oil burns off when it is started.

Not sure if it is though as he is a legendary bullsh***er

I had assumed it was just a standard feature of a 17 yr old landrover.

l had an old series 11a that did the same and was told it was the valve stem oil seals.

Would valve stem oil seals make it miss as well as smoke????????

Thanks but already tried that, put new set in this weekend but no joy.

Try checking the glowplugs, even though there new doesn't mean they work.

Out of four new ones I got last year three didn't work properly!!!!

Not meaning to sound thick (but I am)- but how would I check them dont really do mechanics.

then do some electrics. you need an accurate multimeter.

Wot with a name like Sparky, you don't do electrics. You could get done under the trade descriptions act you could.

Two ways of checking them :-

1. Using a multimeter check for continuity through the plug no continuity = plug nackered.

2. Even if you get continuity the plug may not be up to scratch. Hold the plug in a vice on the hexagon bit, connect the vice to the negative terminal of a 12V battery and connect the positive terminal to the top of the plug. within a few seconds the plug should glow red hot from the tip downwards.

That was the trouble with the plugs I bought they were OK for continuity but didn't glow red hot.

Thanks for that - they call me sparky cos my names Mark - lol.

pretty sure they are not polarity sensitive?
(heating elements)

Ooops I hope not.

The way l've always checked em is, disconnect the bus bar/wire that joins them all together, then run a live wire from the battery and flash it on the top of the plug, if it sparks it works if not its knackerd.

checked voltage & it was a bit low - fitted new wires and connections all seems ok now - Thanks to all!!!
