Technical fiat doblo 1.3 sx multijet problem with white smoke and no power

[handsomebeast]

hi there, bought myself a second hand doblo 1.3 sx multijet a couple weeks ago, the turbo had seized, so i got that replaced with the turbo feed pipe, oil pump, water pump, sump was obviously taken off also, and timing chain kit, after all the work i started the van and all seemed fine, fresh coolant and oil, 3,3 litres of oil checked on dipstic for overfilling and coolant level, needed it for a job i had 210 mile away, so i drove it for the day to see if any problems arose before the long journey and all seemed fine, went to the job and on the way home 45 miles before getting home, the dash warning said insufficient oil pressure pull over, or something to that effect, checked the oil on the hard shoulder and it was dry somehow, so i called my dad to buy and bring me a fresh 5 litre can of oil, and a recovery truck to give me a jump start as the battery wasnt charged enough to start it after having the hazard lights on for an hour and a half, the van started so i paid the recovery guy and got back into the van, as soon as i tried pulling off i couldnt go over 2-3k revs and white smoke was pouring out of the exhaust, so i had to be recovered home, the van is outside now the battery is charging, so my question is what could be the cause of this, the only thing i didnt do was do a component relearn on the turbo but as it was running ok i didnt bother, and after spending a lot of money to get it running i dont know where to start, also i noticed the dpf has had a hole drilled through it and welded up so its more than likely been remapped with a dpf delete map

I suggest a good diagnostic scan to see what is actually on the system and working.
If it hadn't as you suppose been remapped /dpf bypassed etc. I would say it needed a good Regen and a long run with DPF additive in tank to clean the system. As in engine at normal temp 90 degrees in middle of gauge, bottle of DPF additive in the fuel tank full of fuel, then a non stop run of around 30 miles with revs ideally between 2-3000 rpm.
However that would be on an original vehicle with no alterations mechanically.

thanks for the advice, my mechanic has a scanner ill get him to hook it up later on, when the batterys charged and ill post results

also took off the intake pipe to the turbo and it is leaking oil but its a brand new turbo, https://www.ebay.co.uk/itm/316142741711

When you say it is leaking oil from the intake pipe, do you mean the side where the air cleaner is or the side nearest to the inter cooler?
Generally I find that supplier to be good.
Incidentally a faulty/blocked DPF can knacker a good turbo.
Having said that in your previous post you mentioned a running out of oil, just a thought but if the previous owner had gone the route of DPF bypassing and possible Remapping then presumably he "Had the need for Speed" and maybe flogged the t*ts of the Doblo before you bought it and now engine is burning oil etc.
If lots of piston wear then "blowby" can push oil out of breathers etc into intake pipe and on a run burn off enough oil to run out and damage engine even further.
Surely your mechanic will have a view regarding this?

the side where the airbox is, havent got the tools to check the exaust side

That is the breather side.
Get your mechanics view regarding the engine overall, they are not exactly a strong high performance unit in my view for tuning and driving hard.

i noticed theyre not the greatest performing engine ive driven but it was sufficient when it was working okay, i just looked at the turbo out of curiositiy as it was easier than checking the injectors to diagnose where the smoke is coming from and why, as i read injectors can cause white smoke, and my mechanic is my nexdoor neighbour so im just waiting till he gets home to try and see whats happening, its only done 105k now and after replacing all those parts i thought it would be fine, i was going to buy a new dpf and get the vlinker to get the map back to stock or as close as i could but this happened

I agree they are good enough for everyday work and a lot have been made, my concern was if previous owner had been less kind with it shall we say.
I have the Vauxhall Combo 1.3MJ version of that model and also two Fiat Doblo 1.6s and had an earlier Fiat Grande Punto 1.3 MJ so familiar with them. Although my old 1.9JTD Doblo in the past was a far more powerful engine.
