Please no not a head gasket again

79 Spider 2000

Just replaced the radiator, water pump, timing belt, thermostat and heater pipe behind the water pump. It had been loosing around 10 ounces of water every 100 miles or so. The radiator was very old and I saw a very slow leak around the top seam on the passanger side so I did all the mentioned replacements.

Well it still leaks about 10 ounces of water every 100 miles or so. There are no visible leaks anywhere inside the engine compartment or around the heater core. The ground is dry under the car all the time. I don't have any milky oil under the oil cap. I don't have any oil in the water. When I start the car cold in the morning it fires right up and runs on all cylinders right off the bat.

Any ideas where this water may be going?

John,

Advance Auto Parts, O'Reilly and so forth loan tools.

You need their pressure tester. It works great to locate minor coolant leaks, although if it is a head gasket it probably doesn't work for that.

Anyway, a tiny coolant leak when under pressure may never make it too the garage floor. It often is evaporated by the heat of the engine.

The tester is good to use since the engine doesn't have to be running or even hot. Just attach the cap to the radiator opening, pump it up to 15 psi or so and listen for a hiss or drips. If its a minor leak you'll find it. Mine was a pinhole in the line running along the back of the engine to the water choke. Never would have found it without the tool.

Good luck and let us know.

Thanks I'll give the preassure tester a try this weekend,
