Now I know this is nothing to worry about, its done it for years but its starting to get on my tits abit.
My engine is occasionally left running for long periods of time, just idling and its incredibly noisy.
It not a clunk or a tappety noise, its just a high pitched screeching noise, possibly a belt?
Any areas I should be looking at?
I seem to recall somone ages ago mentioned rubbing candle wax on the belts, would that help any?
