[QUOTE="sannabay, post: 599042, member: 14786"] Hopefully its not your main bearings. There Must be end play, it needs some slack. I'd start there, check the big nut that holds the flywheel on, the four cylindrical pegs, the running face of the flywheel, shims, seal etc. Any wear, balling of metal on the surfaces might indicate the source of the noise. Also check the crank pulley, inner face about 3mm away from where the centre is welded to the sheet metal for a radial crack. I wouldn't worry about a tiny crack, but you'll know if its bad. I've been through all this. Threw money at the engine shop for an exchange and the noise went away! it was the main bearing. [/QUOTE]
