OilIT Posted April 11, 2008 Share Posted April 11, 2008 I was in the defender 300tdi today, sat in the drive with it running for about 30 mins whilst I changed a radio - then switched it off for about 5 mins. then started it up to go up the road, as i went up the road, it belched smoke out all the way - white smoke. I then noticed that the indicators, fuel gauge and rear wash wipe wasnt working, so went home changed the fuse, and started it up again and went back up the road and no smoke. Now I am sure the fuse is a red herring, I am thinking that it was due to the 30 mins of running in the drive at idle - but why I am still intrigued about. I know I have a problem with a vaccuum developing in the tank when the fuel tank gets low, as the cap is hard to get off - a job I just haven't got around to fixing - but not sure this is the cause? Any thoughts appreciated... Jerry Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted April 11, 2008 Share Posted April 11, 2008 My tdi used to do that..... if it was on idle for any length of time, the first time i booted it, it would smoke like the Simpsons "springfield tyre fire" for a few seconds. don't know if it means the turbo is past it? (oil leaking into it?) Quote Link to comment Share on other sites More sharing options...
Cat_J Posted April 11, 2008 Share Posted April 11, 2008 My 17 year old TDi will puff out a bit of smoke when the engine is started but after tthat never when driving. I never have it running in the drive so I don't know if it will after that. Quote Link to comment Share on other sites More sharing options...
JST Posted April 11, 2008 Share Posted April 11, 2008 try and FFR on idle for 2hrs every 6hrs for a week or so and see how that smokes! i would attribute it to the idling and not getting warm. Quote Link to comment Share on other sites More sharing options...
GBMUD Posted April 11, 2008 Share Posted April 11, 2008 Yep, long period at idle filling the breathers with gunk which then all gets pulled through when you start to drive it - you will often see the same thing when lorries pull out of their yards in the morning having sat at idle for half hour while the driver makes tea, fills in logs, tacho charts etc... well, mine used to.

OilIT Posted April 11, 2008 Author Share Posted April 11, 2008 Thanks guys, I will test the idle theory tomorrow and let you know - at least I feel a bit better now though ! Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 11, 2008 Share Posted April 11, 2008 We did a load of night work a while back where the guys were sat in the back of a transit with the engine idling for ~8 hours per night, by the end of the week the thing sounded like a piston was going to pop out the side of the engine - a quick and very smoky blast up and down the motorway and it was good as gold. If in doubt, run Redex through it for good measure. Quote Link to comment Share on other sites More sharing options...
Cat_J Posted April 11, 2008 Share Posted April 11, 2008 If you were to how often would be good to use Redex and at what concentration. Is it 50ml per gallon? Quote Link to comment Share on other sites More sharing options...
white90 Posted April 11, 2008 Share Posted April 11, 2008 Turbo oil seals the cause at tickover the seals if worn allow seepage past them same effect as coming down a long hill on overrun happened to us in the Pyrenees sorted when turbo refurb'd Quote Link to comment Share on other sites More sharing options...

It's written on the bottle I believe For a good cleanout I tend to just bung a load in, never seems to do any harm. Quote Link to comment Share on other sites More sharing options...
Cat_J Posted April 11, 2008 Share Posted April 11, 2008 Does it just burn like diesel then? Have you noticed any difference after using it? If so I might have to go and get some tomorrow. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 11, 2008 Share Posted April 11, 2008 Never used the diesel version but we proved the petrol version worked by adding it to half the karts at the indoor track and watching the lap times drop consistently when we did. Heads were cleaner when serviced too. Quote Link to comment Share on other sites More sharing options...
Cat_J Posted April 11, 2008 Share Posted April 11, 2008 Okay, last question, honest. How often were you adding it? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 12, 2008 Share Posted April 12, 2008 Okay, last question, honest. How often were you adding it? No schedule, occasionally we bought a bottle (usually prior to a big servicing binge) and ran it through the fleet and each time we did it showed in the lap times. Personally I'll buy a bottle every so often (if I'm in Halfords for example) and will run a few glugs of it through when I remember at the petrol station.
