Engine Failure? Need your advices

[myrtille2004]

More news. I first checked my intake manifold bolts as recommended, and surprise, I found 2 of them loose (one opposite of each other, driver side). I then removed all spark plugs (see pictures) and found a couple of them wet... This explain probably that the manifold intake gasket failed first, then the head gaskets after. Why? I checked compression of my 8 cylinders: #1-4-7-8 are between 130-150psi and #2-3-5-6 are at 0psi. That's why I think my head gaskets, both sides, are broken. What do you think? Another surprise, the plug #7 tip was fully bended (see picture), I cannot explain it since when I installed all of my plugs they were in specifications. Is it possible it overheated? What can cause such a bend?

This is probably what happened for the coolant leakage:
1- Manifold intake gasket broke and a couple of cylinders fill-up after I shut down my engine this weekend
2- I tried to start the engine a couple of time Monday, like the engine was lock
3- The engine finally started and a cloud of smoke with coolant came out of the exhaust
4- Because of the cylinder locks, it probably broke head gaskets also
.... any other suggestions? Or my block is crack?

Thanks for your appreciated support!
