Pull the riser off the manifold and see if there's water in the ports, usually in the two center ports. Next, take the manifolds off and pressure check them.

If you don't see any water in the manifold it's either a head gasket leaking into the engine, cracked head/block, oil cooler, intake manifold and a few other things I'm probably forgetting.

As far as the oil, I've had good luck pumping the old oil out and replacing it with a light weight 10W/30 and run it on the hose for 15 minutes, then do another oil change and let it run on the hose for 30 minutes at 1500 rpms. Once that's done change the oil again but this time use regular oil, not the thin stuff...and take it for a 1 hr. cruise and the rest of the moisture should be evaporated......that is if you figured out where the water leak was coming from... ;)

That is only 1 way water can leak out of a head gasket into the motor. If you leak down or check compression and the numbers come out OK it does not mean the head gasket is OK.

what if you pressure the block and heads,holds 15#s for thirty minutes but still had water in the #6 hole, im lost maybe reversion

Start with the risers and manifolds, but then move to the intake manifold. Odds are much better there than a cracked block ets unless you didn't winterize properly etc.
