OK, '87 7-pass gl with well over 160kmiles.  Some leaking evident from heads (drips on both sides) since acquisition, expected to need to redo heads at some point in not-distant future.  Vehicle came to me with a complete spare engine that includes newly reman'd heads, so I was not dreading the eventual need.

Tony Wolf (Wolf's Foreign Auto, Merrillville IN 219/942-0576) had the van for other stuff, when I picked it up he said "Your heads were leaking coolant like sieves!  I retorqued them and now they don't leak."  That was about 9 months ago.  Still no leaks!
