New guy here. Been searching the web for info on the 1.9JTD engine and this forum seem to be the knowledge base of choice.
So hopefully i can still get answers/help/advice even if its not for a Alfa!
The 1.9 JTD engine is in a 2005 Fiat Doblo which is a bit of a project van my Dad bought.
He knew it smoked but we hoped the smoking would be Injector/EGR/MAF related, but its blue smoke and does smell like burning oil? I did check the MAF and EGR but the MAF element is shiny clean and the EGR wasn't that dirty and the valve part moves easily when pulled with pliers.
Even in this cold weather it starts pretty much instantly, so we assume
the compression is okay. After it has started smoke starts to come though, but it doesn't start with a belch of smoke. So again we assume
it isn't valve guides/stem seals?
The steady stream of smoke increases dramatically, as in where the hell did the van go, when you rev it with a big boot full of throttle. So we guess
its the turbo at fault?
Is there a way we can run it without the turbo to confirm this? I was told to remove the pipe from the turbo to inlet and if oil was in there that was all the confirmation I'd need. Does that sound right? I'd love to be able to eliminate it completely before lobbing out on another turbo, so if we can bypass it all the better?
Is there anything else that could cause oil to be in the inlet, e.g. blocked breathers forcing oil down a different route pass the Turbo?
Anything else besides the turbo that could cause smoking in this fashion?
