The mechanic found the threads that connect the tensioner bolt was stripped from the prior timing belt change and had quite of bit of thread locker on the bolt. Is the possibility of a semi loose tensioner bolt or a slowly leaking water pump cause the original timing belt slip? Didn't check the compression yet but the car is sounding, and driving well. No codes and now I can finally start to enjoy the car.I didn't notice any damage to the cam gears. I am surprised to find only the leaking water pump/coolant. Maybe I was just lucky to get a little water to mix with the coolant and cause the slip. I will report soon how it runs after it is back together. Going to check the compression after just in case.
