Undy has a VERY small leak leaving a milky shake like mix of
oil and
antifreeze ONLY in the valve cover. No apparent
oil contamination. Extraordinary steps have been taken to find the leak, no luck, it remains a mystery.
Theory, or question:
With Evans coolant and low or no pressure is it possible there would not be a detectable leak in Undy's cooling system? Something (very small) is pushing water out of somewhere and into the engine area. I theorize that "something" is based on the coolant system working under pressure, 12 to 15 psi would be a normal range, possibly more. NO pressure, no leak, neither of these threads would exist (enter the Twilight Zone....).
