I don't think this is a thread jack since he has the exact same problem. Who knows, he may find the solution, post it here and both he and Rick may benefit.

To pkquest and Rick, I've not heard of timing chain failure on a M60 before, but it certainly is possible. One member here had a M50 that snapped its chain. It was the first time I had heard of it on the robust M50. Are you able to see the rocker arm assembly on one bank if you remove the oil filler cap? If so, have someone crank the engine over and ensure that the valve assembly is turning. My presumption is that it is turning or else the piston would be hitting valves (if the M60 is an interference engine). Plus, I would think that it would be making a horrible noise if the timing chain broke. Hopefully, you can mark this off of your worry list.

pkquest, you indicate that your compression was good after adding oil in the cylinders. How was it prior to that?

Rick, have you checked the compression on your engine? Have either of you determined if you have the Nikasil block? I would not think that this would be the problem because they usually start having problems slowly and manifest with symptoms. It sounds as if both of you had a sudden no-start. It's just another thing to check.

Rick, it may be that you may wind up having to take your car to a BMW mechanic for a diagnosis.
