Also Next time you take off the manifolds, you'll see rust in the exhaust ports in the cyl head if the water from either a leak or...

Not necessarily. Is there any water in the motor oil? Another test is to run the motor for about a half hr and then pull the plugs...

The pic of the 3 plugs the one on the left and the middle def look rusty. BTW use Delco Marine plugs instead, they are more rust...

Is the exhaust manifold on the closed cooling circuit? If not then it has to be drained, and even if it is, the elbow should be drained...

If you start it that way, they won't get cooling as they should, that can overheat the exhaust rubber hoses and flappers. I don't think...

If it were a leaky intake manifold, that would put water right in the oil since it would leak into the cam valley, I doubt that it would...
