Ok, i'll have a look at the crank pully tomorrow and i'll check the mounts when as soon as i have a bit of spare time and can get the car on a level surface to jack it up. As to checking the big end bearings, I might have to get my friend to help me with that one, just quickly looked it up and I think I'd rather someone with a bit more experience remove the sump. If the crank pully is turning out of balance then what should i do?
