a leak down test consists of compresing the cylinder and listening to the exhaust and intake valves.if you can hear air comming out of either you have a failure.i would get a compresion tester,pull all plug wires remove one spark plug at a time install compression tester(screw in kind)and crank engine until preasure is at max then simply listen to the exhaust valves for air leaks,then listen to intake vaves for air leaks.

You'd be wasting your time, as that will not work. You must have a pressurized air source and an adaptor to do a 'cylinder leakdown test'.
Perhaps 87supraturbo was refering to a cooling system pressure test. If so, it would be cheaper to have a shop do it, as cost of the tester is not low. Plus a shop can test for a BHG at the same time.
