water leak

No more guessing. How many more times do you want to do stuff that might not accomplish the desired results?
If you find actual liquid water coming out the drainplug,then;
AS already mentioned,You need to perform a cooling system pressure test. There are three parts to this; cold engine/engine off, fully warmed up at 185 or better/engine off , and fully warmed/ engine running.In all three cases I would pressurize to a minimum of 15 psi. In the first two cases I would be looking for a pressure drop, and then figure out where the coolant is going. In the last case I would be looking for a pressure rise, indicating compression entering the system. If that happens, then the next test is a cylinder leakage test.
A compression test/cylinder leakage test might be helpful.But I would wait ;til the cooling system results are in.
And as also queried, is your PCV working?
And finally is your cooling system coming up to temp? and are you running it long enough to vaporize the condensation (that forms in there at this time of year), from the last run-time?
And yes it is possible for coolant to enter the crankcase from between the timing cover and the block. This is a hard thing to diagnose and thankfully,rare event.
But if you want to change the intake gaskets again and again and again......
