My 90 GL has had the same problem when the weather
gets cold from about 80,000 miles on - it's now got
140,000 and I still haven't fixed it.  Not
recommending anyone else follows my example, but by
keeping a careful eye on the collant level (and
knowing via compression tests that it's not a head
gasket to cylinder leak but only the water jacket)
I've put off the expense of pulling the heads for
about 5 years or so.  Maybe living in San Francisco
area helps weather-wise.  I've gone through the hassle
of flushing and using the moroso ceramic sealant -
didn't work.

Just my 2cents...
