All cylinders filling with water
The situation is not funny at all but it IS funny to think about all these gearheads mulling this over like dogs with a bone.
I guess I'm one of the dogs cause my brain keeps chewing on it even though in comparison to most of the guys here I know next to nothing.
Judging by the description of events, the leakage is no small little seep. He shut it down, not sure how much time went by, but not more than an hour I'm guessing and he's got full cylinders!
Like I said I know nothing. I just have a hard time imagining how improper clamping can allow that much flow unless the heads are flopping around loose. But a crack that opens up with heat or unsealed passage somewhere that leads to all cylinders, combined with a pressured up cooling system...
I guess I'll vote for water through the intake.
