Driving home tonight and turned the corner and I started hearing like a grinding/rubbing noise from beneth the pedals from the drivers side, coming near the wheel area, so carried on driving and pulled into a bus stop thinking it may be a lose hub cap or something but it wasnt. Funny thing is aswell when I pulled in to stop the car died aswell. Started it up again and continued to drive (slowly) home, the noise was coming and going and the engine seemed very lumpy no very responsive (loud tapping noise coming from the engine block itself), got home and left the car. The car was struggling to get home. I thinkit could be the drive shaft or problems with the headgasket (maybe not all the pistons working but im no mechanic!!) anyone here know what it could be??
