Probably not, no damage other than cracked rings. Mechanic thinks that could have occurred with a small amount of water present. I am well aware of the prohibition about cranking too long. This start was a slow and rough start, very much unlike the past history of the engine. Subsequent starts, even days later, were just fine. This engine has always fired right up, except when it was time for injector service and the weather was cold. New injectors solved that problem. But, on the trip home after this rough start I had the first oil leak ever, which led me to high crankcase pressure, which led to the engine being removed. I was smart to get to it quickly. I probably only had 3 hours of run time on it with the oil leak.
