[broad]

how would i no if turbo has gone or going?

any ideas? thanks

What type of oil was used?
Where does the level sit once the engine is warm (not hot)?
When the oil was changed, was the oil filter changed as well?

For the turbo, you should hear it when the revs reach 2000rpm
A failed turbo will run the engine when it is switched off
A turbo nearing failure will normally show white smoke on the high revs and on idle can often show blue smoke
Equally, near failure you will hear it on idle (which you should not normally be able to)

actualy an oil change was done but couldnt get the filter off.didnt have the correct tool. would that make it feel slower tho? 3 mechanics said it would be ok....?

Please refer to original three questions from post 2
I can't offer any further advice until all of these are answered

Next set questions after that will be
How long since last service?
What does the Service Indicator show?
How long since the fuel filter was replaced?
