last nite i got followed around by a few "thugs" who are known for stealing cars around the area, anyway i usually park the car outside but this time i had to park it in my dads garage who unfortunetly has a very steep garage, and because my car is sitting so low, i had to over rev my car to climb it slowly, ridding the clutch, the whole car stunk like clutch and the car still scraped ...

now i dont ive got a problem and i dont know if its a result of doing that to the clutch, I realised that when i turn the car off it:

Firstly, makes a squeeking noise (sound a belt makes when its too tight)
Secondly, will follow that by a bump noise.

This only happens as soon as i turn the car off.

what is that?

 

shiny flywheel syndrome, clutch plate squeals then when it settles it thumps ( due to riding the clutch) over heated flywheel "glazed"
