Guys really need your help here because I have lost my mind.

So my 2010 RRS 3.0 tdv went in for both turbo replacements.......thankfully I have warranty...indy garage diagnosed that the off side turbo was leaking so claimed and got both turbos done..

Now after the first change they did a road test and the offside was leaking so they got another turbo in and changed that. Again yesterday road test and that turbo is showing signs of leak.

Now they are saying the turbo engineers need to do a report and it could be the engine its only done 70k miles why would it be the engine?

The car has been at the gargae since January and their courtesy car is a nissan micra so I have been hiring off thrifty since then so I am down in £££££££££££ & about to lose my f****** mind today.

Anyone ever seen anything like this before? what can i do now?

It would be unfortunate if it was just a problem with The drain pipe.
On a serious note if the turbo has good clean oil at the correct pressure and the drain is free then it shouldn't blow a turbo. If the car is burning oil it can only be getting in by a couple of locations. Heavy breathing, worn piston rings or valve guides. Turbo . That is pretty much the only way oil can enter the exhaust .
