Ok, I am normally a 240 person and I was TRYING to do the trick where you run water in through the intake via a vaccum hose and it cleans out carbon from inside the engine.

So I try this on an 850 whiteblock, I use the vaccum port on the right of the intake manifold where there are two ports, I use the top one. I start the engine and it sucks the entire jar of water in in about 2 seconds, klunks, and dies.

The engine will not even turn over now, does anyone have any idea how much damage I have done and what it will take to fix it?

This trick always worked perfect on redblocks, I don't know if it just doesn't work on whiteblocks or I really pickes the wrong vaccum port.
