All Praise The GTI 3 Posted February 14, 2008 this could be the problem: ''also the guy has been running it on bio diesel'' which pump has it got as i think the lucas ones dont like it Share this post Link to post Share on other sites
Anthony 1,002 Posted February 14, 2008 Is it using coolant and/or pressuring the cooling system? Mine was very smokey when the HG went, worse when cold, and there was no oil/coolant mix - and HG's are common faults on those engines. Most TD engines will chug and smoke for a few seconds on startup thanks to a combination of failing glowplugs and injector/cylinder wear, but they should clear pretty quickly and certainly not smoke and chug when hot.

Anthony 1,002 Posted February 14, 2008 this could be the problem:''also the guy has been running it on bio diesel'' which pump has it got as i think the lucas ones dont like it Generally as I understand it, Lucas pumps don't smoke on vegoil, they tend to sieze or snap the input shaft - equally terminal results either way really. My TD did smoke and chug a bit more than normal when running high concentrations of vegoil, but again, only from cold - clean as a whistle when warmed up.

gerry 5 Posted February 14, 2008 system isnt pressurised and it smokes when it feels like then engine starts to chugg but its not missing ie if you hold revs say to 2k it sticks at 2k but still smokes...... its doing our heads in as before we started it up and it was ok for about 5 minutes then all of a sudden decided to chugg and start smokeing!!!

Mikey S 29 1 Cars Posted February 15, 2008 system isnt pressurised and it smokes when it feels like then engine starts to chugg but its not missing ie if you hold revs say to 2k it sticks at 2k but still smokes...... its doing our heads in as before we started it up and it was ok for about 5 minutes then all of a sudden decided to chugg and start smokeing!!! it sounds like injector drip. usually the pintles in the end of the injectors wear and the diesel litterally 'drips' into the pre combustion chamber which causes it too smoke like a bitch. whip the injectors out and get them tested at a local diesel specialist. if there shot, which more than likely they will be, dont buy secondhand, its not worth it in the long run.

welshpug 1,656 Posted February 15, 2008 ROFL! if you really want to... but they are for petrol Electronic injectors diesel injectors are not diy serviceable, you can remove and replace them yourself, but any further work requires very specialised equipment.

McDude 33 Posted February 15, 2008 ... it just constantly puffs cloudy coloured smoke oil and water are not mixing "engine seems to chug" when it gets fully warm smoke isnt as bad as stone cold but it is still bad and deffo not normal What do you mean by 'cloudy coloured'? Do you mean white? White smoke means water in fuel, usual culprit is the head gasket. If the smoke is blue-ish then you've got oil in fuel and if the smoke is black you are over fuelling - if black, check intake air for leaks before going down the tougher route of injectors. You could have a split or loose hose which is very common on turbo diesels. also the guy has been running it on bio diesel...... At the moment engines are rated to 5% bio-diesel, if he's been running this then fine, if not then oh crap! I know the bloke down the pub says he knows someone who knows someone been running veggy oil for years with no problems, but really no one has done proper durability tests to see the long term effects of running even moderate levels of bio-fuels (ie ones mixed with regular diesel). Known problems are increased blow-by meaning that your oil could be diluted. If you suspect this change the oil, though this won't be causing the smoke. There are also known issues with wall wetting from unburnt fuel and resulting stripping of the oil that lubes the piston rings. It could have led to scoring and to oil coming up into the combustion chamber, this is also exacerbated by the oil dilution - hence blue smoke. Share this post Link to post Share on other sites
gerry 5 Posted February 15, 2008 i would say its grey/blue but very very faint blue fired it up today after changeing both filters air and fuel also put some stp injector treatment direct into filter about 2 table spoons full and rest in tank. it smoked when started for say 5 minutes then ran normal no smoke ticking over nicely then all of a sudden say 4 minutes later started running lumpy and chugging again then the clouds of smoke started anyone i kept it running like that for say another 5 minutes or so then it just started to run normal again no smoke or very little left it like this for say 15 minutes (revving it etc) and no smoke at all came back??? waiting for it to cool down fully and gonna see what its like this time?? ie has anything worked that we have done today.... think its really wierd though anyone else any other ideas???
