Assuming the oil was a synthetic, the residue would have provided a limited amount of protection. Remember that the dipstick may appear dry while there is still 2 or 2 1/2 quarts of oil in there. (Although a serious leak may indeed have allowed the oil to drop SERIOUSLY low if the engine was run long enough.) I'd drain and replace the oil, run the vehicle to see how long it takes for the engine to lose a quart, then see if it can be determined when the oil was last topped up. It may be the oil went below dipstick level but was still sufficient to avoid major damage. Also consider ANY OTHER possibilities for that noise you're hearing. If the car will soon need a new clutch, it wouldn't be too much more work to pull the engine with the trans and replace bearings (if that is the problem). In a message dated 3/29/2010 7:55:36 A.M.

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
