Bitter taste of defeat! So much coolant in the oil pan.

I don't want to add unnecessary worry but I saw a Ford 390 once that someone used an incorrect motor mount bolt (it was too long) and fired it in with an impact--too bad it went in too deep and the bolt broke the cylinder.

I have always looked at the number one cylinder and there is a timing cover bolt hole that if one wasn't careful a too long bolt could break the cylinder. This is a worst case scenario OP, I'm sure it the t-cover. I'm amazed at how infrequent this problem really is-there are many opportunities for the waterpump to t-cover to block interface to cause this to happen. When I dyno a small mopar I am always monitoring the dipstick and it aint' for oil level. Good luck. J.Rob
