Grinding noises when the clutch is down
Plus slipping
Plus smell
Could be clutch and release bearing
But then again it's had so many part thrown at it and so many thread opened some appear to stop without any resolution, jumping in without reading the other 400 post plus answers it's hard to know what going on
Burning smell,.plus poor economy,.plus poor acceleration could be binding brakes and clutch release bearing
MAP sensor was covered in oil,.poor economy,.poor acceleration, plus burning smell could equally be cracked breather pipe, fawled MAP and input bearing
And so on
We need to not guess could be this that on other and start testing and eliminating things
Did this ever get fixed by the way

find a safe, quiet, bit of road go about 10 mph press the clutch pedal down and select 5th gear raise the revs to around 3K and hold it there release the clutch pedal, if the engine struggles or stalls, it's likely fine, if the engine keeps running the clutch is slipping
