[QUOTE="hc803, post: 452014, member: 10139"] Have you pinpointed the general area of the sound by running it on muffs in the driveway? Could be your timing belt, easy check it to rev it up until you get the sound then shoot the belt with some belt conditioner (or water or whatever) and see if that changes the noise. Might be worth investing in a mechanic's stethoscope to pinpoint the source of the whine. Cheap tool but I've used one for noises in both cars and outboards. Just watch for moving parts when you're probing around! [/QUOTE]
