Has anyone got any idea why a 2.8 TDI 2005 fiat Motorhome with mileage of 22k should have blue smoke coming from the exhaust, and seeming loss of power. Please any suggestions would be appreciated.

On our 2nd MH now a AutoTrail Savannah which we're absolutely delighted with
Hi sorry to hear your problem but in my experience it can be a number of things- diesel somehow thinning the oil,problems with the piston rings,incorrect oil being used-that is too thin if you like oil but I'm sure wiser people will be on here soon with more helpful info. Hope you get it sorted soon at not too much expense

22,000 miles after 10 years? If that is a genuine mileage it could be the bores became rusty from being parked up for months on end. This would play havoc with the rings.

A Woosh bang
best bet is to drive it to your nearest garage for a diagnosis.. commercial vehicle garage rather than a car one.

Poss turbo problem, or injectors need a clean? Injector cleaner, but as said a trip to the garage for an informed view.

blue smoke coming from the exhaust, and seeming loss of power.
Like the others , it is probably the piston rings, the giveaway really is the seeming loss of power, the blue smoke is usual on diesels that haven't been started in a while. Have a look around any marina when the power cruisers are going out. After a few minutes it usually clears, if that is not happening on your motorhome, then there would be a high probability that you have piston rings, that are stuck, worn or broken. hope it helps.

Cold / Hot engine ?
Mine lays down a smoke screen from cold if left for a while in very cold conditions ,once warm and on a run well within limits just an older engine 2.5td needs a service which I will give it when the weather gets better and I have the time .
Give Dave Newell a post , he`ll let you know possibly .
Hope you sort it

Blue smoke will almost certainly be burning engine oil.
As mentioned previously, rings, valve stem seals or the turbo could be the problem.

I am so glad you got it sorted out. It looks as if the piston rings were sticking but it is great news for you to have solved this. Happy motoring!

Thank you all for your help it was for our sons rapido motorhome, adding engine cleaner etc seems to have done the trick, thanks again to you all.
Out of interest, what make of engine cleaner did you use.

He used a combination of two both Wynns clean burn diesel cleaner 325ml & Wynns extreme diesel system cleaner 325ml added to half a tank of fuel and then he ran the tank to vertually empty less than two gallons. It now seems to be running perfectly now.

Thanks, I will do the same for a cleaner burn.
