If there is lots of water when you pull the valve cover, there is likely to
be lots in the sump, too. But before you pull the head, check the aluminum
plug in the head: I once had a similar problem after an engine rebuild and
it turned out the plug had disintegrated and was leaking (and I hadn't
replaced it). It's a much quicker and cheaper fix than just about all of
the others causes.

Subject: [TR] Overheating Question
Investigating my overheating in the TR3A, I found loss of coolant in the
radiator. I checked the oil in the sump, but no white curdling suggesting
water in the oil. Pulling the valve cover, though, shows lots of water.
Sounds like a head gasket, but wouldn't the water be in the sump too?
