Have you tried another radiator cap? If its not holding sufficient pressure,
you could be losing coolant through steam loss. You didn't say how much
coolant you were losing either. I was having a problem with coolant loss on my
67BGT and I could see it was going out the overflow pipe. I tried another
radiator cap. But what happened, as near as I can tell, is that my BGT likes
to run a fairly low coolant level and so every time I topped it up, it just
ended up spitting it out. I think it likes to run with a coolant level maybe
1" or so below the fill neck and since I have ignored it, it hasn't shown any
need for coolant. Granted its a BGT with a nice oven inducing black interior
so I don't drive it when it gets really hot outside. Thats when the B comes

I have a problem with coolant loss in my MGA.  It's not losing a lot of
coolant, but it is enough that I have to watch it.  I know my car pretty
well (I do all the work on it, and have owned it 7 years)  - and I'm at
a loss myself at trying to find where the coolant is going.  My latest
suspicion is a crack in my head.  I've  watched my exhaust and had
people watch it, and no white smoke - so I don't suspect that I have a
bad head gasket.  My oil isn't frothy either - so I really don't suspect
a blown head gasket.  I've looked for leaks all over, and can't find
any.  I have a coolant recovery bottle for expansion, so I shouldn't be
leaving it on the ground like most MGA's either.  None of that makes
sense though, because I know that it is going somewhere - and that it is
either be burning or leaking.  Anyone know how much coolant one loses
with a small crack in the head??
