The problem here is that the head bolts were reused. When stock head bolts are used, they stretch when torqued. When they are loosened, they do not return to their original shape. These bolts are called Torque-To-Yield, and should not be reused. I suggest spending the extra $30 on ARP bolts over OEM. ARP bolts can be reused over and over.
A reason you may be consuming more oil than normal could be the valve seals going bad, and letting oil seep by them. You could do those yourself if you change your headgasket. You will need a cylinder head spring compressor to get the springs back on after you pop them off though.
So my suggestion for the current issue with the coolant, is the headgasket/new rod bolts (I recommend the ARP bolts. If you ever have to take the head off again, you dont need to buy new bolts)
And if you are willing to do it, the valve seals. (You can get OEM seals for 3.08 each from the dealer
AcuraOEMParts.com or get some Fel-Pro seals from the local autoparts store.)
