Does it sound like a metal knock under one of the valve covers? When my engine went thats what it sounded like. It ended up being one of the main bearings. I had to replace the engine. Not saying thats your problem but mine sounded just like that. It started knocking and there was a loss of power. I remember seeing something on here about long turns and oil cavitation. I think thats what killed my motor. The roads I drove on everyday were full of them.
