hoss1720 Posted August 17, 2011 Share Posted August 17, 2011 Driving home from work tonight when all of sudden,massive amounts of black smoke from the exhaust! Pulled over very quickly and turned engine off - engine wouldnt stop -very high reving for about 5 seconds -until I managed to stall it. I got a tow home off a friend and have begun to start stripping it down. I have managed to get the turbo and manifold off in one. I want to know what my best options are - and is it likely to have damaged anything else engine wise. Sould I get this one repaired or get a new one? I am a little dubious about second hand as I dont want it happening again. lastly - what is likely to have caused it to go? Quote Link to comment Share on other sites More sharing options...
crclifford Posted August 17, 2011 Share Posted August 17, 2011 Hoss, This sounds very much like my old TD when it gave up the ghost!! I had tons of smoke out the exhaust and when i pulled the keys out of the ignition & the engine carried on running! However i did then replace that old engine with a 200tdi so i can't say what damage i had done to the engine! Someone should be along that knows a bit more soon!!

Landy-Novice Posted August 17, 2011 Share Posted August 17, 2011 (edited) by the sounds of it, you've had a runaway diesel!! if it was only 5sec the temp MAY not of hit the 'beyond repair' moment but the turbo WILL need replacing/rebuilt. but i suspect best option is a full rebuild i take it look something like this, just not as bad? after your experience, i would of needed fresh underwear! and the answer to why is. http://en.wikipedia...._engine_runaway gives a detailed description of the fault and how to stop the engine in the process. lets just hope no green right activists seen the incident !! i hope this helps you!

Somethingwitty Posted August 17, 2011 Share Posted August 17, 2011 Is the turbo definately the cause? If the seals went on the turbo and dumped oil into the engine inlet then yes it could cause this but I would have expected blue smoke. Black smoke is partialy burnt fuel and prodigious quantities the result of A LOT of fuel! Failure of the diaphram in the top of the injection pump is rare but has happened and could allow fuel into the inlet (ie over-fueling massivly). Stuck rack on pump possible but sounds like here it ran away up rather than merely got stuck at a high power setting. Unless the cause is very certainly blown turbo seals (or else over-filling oil) then I'd check the diaphram just in case... you'd be threaders to fit a new turbo and have it happen all over again! Stalling it in 5th is quickest method if driving, blocking intake also effective, beware however that a Safari snorkle for example needs the whole snorkle head covered else it continues to draw through the slit in the head by the jubilee clip.
