call around to local autoparts stores. here in new england we have autozone which will let you rent a tool for free with a credit card to hold it. just get a leakdown tester and find the bad cylinder. even a compression tester should tell you the bad cylinder.

I've had this happen before and it wasn't a head gasket. I thought it was, until I pulled the head. just to be safe, i pressure tested my block and found an exhaust port on each side of the motor was leaking exhaust pressure into the coolant. block had frozen long ago and actually had about 30" of weld in the pan rail.
