As Ken said, the noise you're describing sounds like bad rod bearings. If you pull the pan now, you might be able to save it with a set of main and rod bearings. Or, you drive it and take out some poor biker when the next batch of oil sneaks out the hole in the block made when the rod makes a break for freedom through the block. Sometimes they just have to see daylight after a long Winter.

Hi, A "friend" of mine ran their 99 mk2 with low oil (read: this could mean none) for some time. It was eventually noticed when the engine started making noises. Oil was added and it still running. I took it for a spin at the weekend, it accelerates + idles fine, no noises, but when lifting off or *just* slightly applying trottle it makes a cyclic deep click noise. Its been suggested that the crank is done for, but it sounds more top end to me.. actually.. the engine feels pretty strong. I suspect its had its engine wrung out on a regular basis too ;-) What should I be looking at first here? What kind of damage? Likely the noise is crank floating back and forth? Cheers, Steve
