Daryl,
How long had the engine ran before the oil leak to showed up? Is this the
first time checking the water after the rebuild? Have you re-torqued the
head since the rebuild? Sometimes after everything gets settled and
stretched small leaks can start showing up. If there is a bad seal between
a water and oil passage, the higher pressure oil may be getting in the
water. Re-torquing can seal these up.
Before taking off the head I might pull the distributor and drive the oil
pump with a drill. That way you can get oil pressure to check your oil
filter bypass. Pull the valve cover and check for oil flow. I found a
clogged passage going to the upper chain tensioned on a U20 that way.
