According to my book, with a warmed up engine, the compression should be between 156 and 164 psi. the cylinder pressures should be within 14 psi of each other, and absolute minimum is 128 psi. If any of the cylinders is below 20 psi of any of the others, you have a serious problem.

Also, you can use a cooling system pressure checker to help identify the leak. Make sure the system is loaded with coolant or water, attach the pressure tester, and pump up to 16 psi. The pressure should hold, but I suspect it will steadily drop. The pressure will also force water out through the leak, and make it's location well known.
