Has anyone had or heard of lower intake gasket leaking (gasket between heads and lower intake ) i think i might have had one leaking took head off found small amount of water on one lifter and lower intake looks like it has been leaking there is a water leak mark on bottom of lower intake manifold. There is no water in engine oil. No water fouling on spark plugs. On signs of water on pistons or valves. I am going to check all bearings tomorrow after work
 
It can leak, I've seen a few threads about it. Try searching for it and You'll see a few that might help.

However, check things like around the coolant sensors or the Thermostat inlet housing. That fan can blow leaking coolant anyware. I had a leaky thermostat housing and thought the same thing...Lower intake leak...
