got a coolant pressure tester? Use that and if it starts loosing pressure right off the bat then look under the car...if you don't see anything leaking then you've most likely have a BHG. I know since it's happened to me. 3 BHG's within 4 years, due to bad head work from the "previous" shop.
I second the coolant pressure tester. The kind you rent at autozone will not fit our radiators.. but you can take a leak down tester or any kind of pump that you can control the pressure and hook up a hose to the rad overflow nipple.
Check out my for sale post where I post a video of the leak test.
Since I have experienced two leaks in a year at the waterpipe behind the exhaust I will suggest you look at that too. It can manifest as a very slow leak which evaporates once it hits the hot exhaust.
2 in a year and I have a case of waterpipe paranoia..lol, kind of like owning a 7m and thinking its always got a bhg.
