Hello, welcome and thanks for asking your question. My name is*****'m a Certified Auto Technician with 30+ years experience. I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

At this time, I think you already answered your own question. from what you are describing, in fact it IS more serious than just timing chain noise. You stated that you found sludge under the valve cover. This sludge was caused by coolant mixing with the oil caused by the water pump failure.

At this time, you WILL need to remove the engine for teardown OR just go ahead and replace the engine as most likely you have spun rod and/or main bearings which means that the engine may need to be overhauled or replaced...

Keep me posted and let me know if you have any additional questions...

Thank you,

Robert

Coolant mixing with the oil causes the sludge that you found. This sludge is throughout the engine. Most likely what happened is this sludge has blocked the pickup screen for the oil pump resulting in oil starvation in the engine. This will cause spun rod and main bearings and eventually catastrophic engine failure..

Keep me posted...

Thank you,

Robert
