Does sound like a manifold u c

Does sound like a manifold u can pull and pressure test it and look for bits of rust and such. Get that engine drained out asap. Motor oil and everything. Water coming it caused hydro lock.

I plan to pull and replace my manifold at the end of this season if it isn't bad yet.

Good luck
 
"The valve timing changes and

"The valve timing changes and your exhaust valves becomes intake!
When exhaust valve is open and piston goes down, water is sucked into the cyls.
Then when intake is open and piston goes up -you get a geysir in the carb(s)!!"
 
"Exhaust!!!
Your description

"Exhaust!!!
Your description and symptoms are next to 'normal'.
Search back in the forum and you will find several with same problem/symptoms -same reason - jumped timing belt!
Get the water out and preserve the engine, but DO NOT try to start with water hooked up until belt has been checked!!!!!"
