Title: Name that smoke
Post by: gords on December 15, 2005, 08:39:29: (mainly) when pulling away, until the revs build up, I get a lot (?) of white-ish /grey-ish exhaust smoke.

Is that normal or does it indicate that something is wrong?

Post by: beast5680 on December 15, 2005, 08:40:41: is it cold when it does it? if so then normal condensation being evaporated from the exhaust is the cause or does it always do it even when hot?

This time of year Gords Its most likely Steam? Or Condensation? But don't take my word for it!

I know it's old and slow, but it's a diesel not a bl**dy steam engine [-X :wink:

I think it does it pretty much all the time!? It's not so much smoke that you can easily see it in daylight, but it really shows up at night time in the following car's headlights!

It seems to stop people driving right up my bumper, actually :lol:

Post by: beast5680 on December 15, 2005, 08:49:00: keep an eye on all the levels and see if they change and when its hot take off the oil filler cap and see if you get alot of chuffing from it as that can be an indicator of pressure build up caused by headgasket gone, my 300tdi smokes a reasonable amount and it always looks worse at night with lights behind you

It is losing coolant/radiator water fairly quickly - over a week or two!? :-k

My cylinder head failed between the water jacket and the exhaust ports - only indication was getting a bit warm on the temp guage and steam out of the exhaust :evil:

Mine also puts out a grey smoke on hard acceleration (foot to the boards) and I mainly only notice it at night. Mine is due to the mods I've made to the injector pump and the larger intercooler.

Yours could be the same so try backing off the injector pump diaphram that we altered in Belgium and see what it's like. If that doesn't make any difference then start looking else where, and get that diaphram back to where you like it! :wink:

Post by: Range Rover Blues on December 15, 2005, 13:12:10: Just bear in mind that burning hydrocarbon fuels produces water as an exhaust product, the cold damp weather we are having will make it very difficult to stay superheated as it leaves the exhaust and saturated steam looks like what you've described (steamtrain).

Keep checking the levels, if it's not bust don't fix it.

Post by: Budgie on December 15, 2005, 16:43:40: The smoke screw wasn't touched Colin, we only did the diaphram and that was only turned through 90 degrees so the smoke screw should be left at the standard setting. :wink:

Post by: petergalileo on December 15, 2005, 19:18:49: Grey and or White smoke - Either water or engine underfuelling (often happens on hard accelleration.

Black smoke - overfuelling, injectors dirty, blocked air cleaner

Blue smoke - burning of oil, too much oil in sump, worn engine.
