Hi all new here so hello.for starters and thanks in advance for any help ! Ive had a browse but still not sure on my problem (im no mechanic)

So to start i believe my turbo went one day driving home , the revs went wild and smoking like hell but cut out eventualy , after this i managed to get it home the next day smoking but running and wouldnt go past around 2000 rpm ! Ive replaced the turbo and intercooler (second hand ) gave it a full serice but its still running badly , ive had it plugged in while the turbo and so on was done and got the results in the pic below !!! Its idling really rough which im thinking is tge maf but doesnt make loads of difference unplugging that but it does make a slight difference , im thinking injectors as there is still some smoke and although it does rev past 2000 rpm now after turbo and so on its not running right at all ! It feels still bogged down , smoking although nothing like before when turbo went and hunting in neutral maybe a slight knocking although bad injectors can cause all of this cant it ?

Thanks for any help people its much appretiated

I'll just add it starts first time no issue there and i have ordered a coolant sensor and new maf sensor ! I did notice that air box side of the maf sensor was joined but loose no jubilee clip for a nice seal , also i get a high oil warning on dash although that has been drained and replaced , was doing that before turbo went as well ??

Bit more info if it helps , there seems to be a slow leak from somewhere , not dripping on the ground but looks to be coming from above somewhere and running down possibly ! And around one of the injectors there seems to be a small amount of oil has settled in a little rut around the injector , ive done the screwdriver test and all seem to be opening and closing including that one ! Theres a couple of videos if it will let me upload them

You have done damage internally when you allowed it to run away you should always try to control the runaway by using a high gear and braking to slow the engine safely.

It is possible a couple of rockers have jumped off it is also possible an injector has a melted tip or it could have melted a piston causing low compression in 1 cylinder so you now need to decide which it is !
