Dr_evil Posted April 22, 2012 Report Share Posted April 22, 2012 Can't really tell, the only way to check if its timing would be to take off the cover and check the marks but for pump can always tune it using the screw and diaphragm Quote Link to comment Share on other sites More sharing options...
WelshLamb Posted April 22, 2012 Report Share Posted April 22, 2012 I think grey/white smoke is over fuelling/unburnt fuel If its only when it starts it might be down on a glowplug or two? Quote Link to comment Share on other sites More sharing options...
bedwards1966 Posted April 22, 2012 Report Share Posted April 22, 2012 (edited) Does the smoke go when when it's warmed up? If so, don't worry about it, these old indirect injection engines are happy to gas you out on startup. If it's still smoking like that when fully warmed up I'd be adjusting the injector pump timing, it's easy to do. All you have to do it slacken off the 3 bolts holding the injector pump on and twist it (make a note of where it was before you touch it so you can be sure to put it as it was if you have problems). I can't remember which way does what, you'll have to experiment. It can be done with the engine running, personally I prefer to stop the engine first. Taking off the injector pipes at the injectors can make it easier, as when you turn the pump they have to bend slightly and it can be hard, then just put them on again. Then run it and see what difference it makes, and adjust it some more until you find the point where it starts best and runs best.

fox hunter Posted April 23, 2012 Author Report Share Posted April 23, 2012 (edited) When it has run about 22 mile to the farm I switch it off switch on then it smokes when I go through the gears then overdrive doing about 60mph it seems to stop or hardley any smoke thanks for the helpthe smoke is doing my head in Edited April 23, 2012 by fox hunter Quote Link to comment Share on other sites More sharing options...
gixer1 Posted April 23, 2012 Report Share Posted April 23, 2012 I think grey/white smoke is over fuelling/unburnt fuel If its only when it starts it might be down on a glowplug or two? Grey/white is water, black is fuel, blue is usually oil....yellow is some tw*t put a banana up yet zorst.... Quote Link to comment Share on other sites More sharing options...

I have done that turning pump to it back to where it runs best, next thing try to get another timing pump change it and see what happens dont know what else to do apart from getting all the farm deisel out trying garage deisel Quote Link to comment Share on other sites More sharing options...
Dr_evil Posted April 24, 2012 Report Share Posted April 24, 2012 well it might just be bad fuel, mine smokes a lot when I run it on veg oil or bad stuff from morrisons but on shell it burns perfectly might just be the fuel Quote Link to comment Share on other sites More sharing options...

You could just connect up another tank or can with 5 or 10 litres and see how it runs. you have drained or changed the filter ? Quote Link to comment Share on other sites More sharing options...
lister1 Posted April 24, 2012 Report Share Posted April 24, 2012 Try changing ya filters. Quote Link to comment Share on other sites More sharing options...
Dr_evil Posted April 24, 2012 Report Share Posted April 24, 2012 Filter shouldn't make much difference, the inline filters are only picking out the crud from the tank not the water. Water is filtered out in the sedimentor at the back Quote Link to comment Share on other sites More sharing options...

Hi what I have done today is changed deisel filter new one, drained all fuel from tank bought some fresh put in and run still smokes but not so bad probably needs a good run or a match Quote Link to comment Share on other sites More sharing options...
Dr_evil Posted April 24, 2012 Report Share Posted April 24, 2012 dirty injectors spring to mind, throw in a 3L petrol with the derv mix or some Redex Quote Link to comment Share on other sites More sharing options...
fox hunter Posted April 24, 2012 Author Report Share Posted April 24, 2012 dirty injectors spring to mind, throw in a 3L petrol with the derv mix or some Redex hi had injectors serviced only last week but i will try the redex, if i put petrol in a match might follow thanks for the idea Quote Link to comment Share on other sites More sharing options...
Dr_evil Posted April 24, 2012 Report Share Posted April 24, 2012 I dont use redex I use something else but I can't remember the name haha, also ignore their instructions. I just dump the lot in when I do it, smokes a bit more but cleans the system properly, bit of 2 stroke in each tankful also helps as it lubes the injector pump so you get a bit less noise Quote Link to comment Share on other sites More sharing options...

Dr_evil Posted April 24, 2012 Report Share Posted April 24, 2012 would a faulty lift pump have anything to do with it lift pump only pulls the fuel to the injection pump, shouldn't effect the smoke colour. If it was over active then it would be black but grey as said suggests bad fuel Quote Link to comment Share on other sites More sharing options...
fox hunter Posted April 25, 2012 Author Report Share Posted April 25, 2012 (edited) Hi guys Thank you for all the advice on the topic much appriciated dont know what else to do other than check timing on fly wheel and timing chain but have been told that if it needs new timing chain with all other parts that would be needed for a mechanic from a landy garage would cost about £500-00 thanks Regards Roger Edited April 25, 2012 by fox hunter Quote Link to comment Share on other sites More sharing options...
Dr_evil Posted April 25, 2012 Report Share Posted April 25, 2012 A timing chain will very rarely need changing, the V8 I rebuilt had done something like 150k and the chain was fine so I wouldn't worry about that Quote Link to comment Share on other sites More sharing options...

Dr_evil Posted April 25, 2012 Report Share Posted April 25, 2012 Just don't let the garage bend you over thats about the best advice I can give you, most jobs on a 90 are simple and can be done by the average person and a bag of spanners Quote Link to comment Share on other sites More sharing options...
fox hunter Posted April 28, 2012 Author Report Share Posted April 28, 2012 OK GUYS we altered timing pump no different so put it back then drained all old fuel, then replaced with £10 worth of new as thought only to find it was unleaded petrol drained that, put new deisel in took for a run doing 70mph only ever done 62mph tick over still smokes abit, question......should the deisel filter when pipe taken of preasurerise my mate seems to think that there is a blocked pipe somewhere due to the gunk of the farm,, Quote Link to comment Share on other sites More sharing options...
