160000 mile 2.5 gen2, failed mot on excess blue smoke, what could I be looking at as a cause? My mechanic said possibly piston rings, and its not worth repairing. Anything else to look for before I scrap it? |

How much will it cost to fix? if you like the van then it's worth fixing. nothing lasts forever and if the body is good then could be worth doing. imagine if you had done the conversion and then the engine failed....you would surely fix it. https://www.perkins.com/en_GB/resources/useful-information/blue-smoke.html yes it may be the rings, it may be many things that's why you need a second opiinion. sorry I did not see this post before I replied to your other one!

Hi, It is possible to be a faulty turbocharger. Disconnect the turbo from inlet manifold, or from intercooler hose and check if there is oil contamination. Edited by Bazil-S, Aug 31 2016, 08:49 PM.

Now that you mention it it only smokes once you start accelerating, at idle there is no smoke at all, am I right in thinking it would be blowing continously if the piston rings had gone? Also, if I do decide to fit a 2.8 does anyone know what engines I can fit as a straight swap? I ve found a 2.8 non turbo lump from a 2001 Iveco Daily thats only covered 81000 miles (pic below) would this be a straight swap?

Hi, You can start the engine with hoses both removed. If on the turbo output will squirting oil it means that turbo is faulty. The engine from that picture is from of the third generation, and less powerful. It may not fit the engine supports. |

Nope, no spraying from turbo, but thanks for your help, think I just need to find out what 2.8 engine is a straight swap for a 8140.27S |

well tried some wynns smoke stop and its not made any difference at, got the engine fairly hot but its still plumes out, it was worth a try! ![]() While I was revving it up my outlet from the turbo to the intercooler popped off (it was loose from me messing about anyway) and oil is spraying out! So the turbo is shagged too! ![]() Pretty sure it should'nt be like that! |

When you say 'the turbo is shagged too' Maybe as basil says it is only the turbo. The problem could be a lot of things hence I said get a second opinion. If the oil has been changed regularly then the engine should be good. It is impossible to diagnose faults accuratley on the forum. I would try to find and old school mechanic/garage and ask them. Maybe have a compression test too. Basil is very good with his info and obviously very experienced with Iveco. If he says it could be the turbo if it is spraying out oil....it probably is. Why not get a second opinion? Turbo is cheaper than an engine. Graeme Edited by graysworld, Sep 5 2016, 05:32 PM.

Yeah the turbo is knackered, but its not the cause of the proble , I ve ran the engine with the turbo completely disconnected and checked for oil in the downpipe, which is clear, so I m just exploring possibilities before I pay out for a mechanic. I ve got some injector cleaner coming to see if that helps at all, after that I ll ask a mechanic to see what they think. |

In my opinion (others are available) injector cleaner is a waste of money. They need to be removed and taken to an injector specialist for proper cleaning and calibrating/setting. Graeme |

I ve added injector cleaner but have'nt had the chance to take it for a proper run yet, its still the same, I ve checked the breather pipe and all seems ok there, no blockages and can feel pressure there at idle, I m starting to think it could be valve seals. |
