After my car was sitting for almost three years I did an extensive head gasket project and some other things including a high performance coil with accompanying spark plug wires, new distributor cap and rotor, new iridium spark plugs, new silicon vacuum lines, fuel filter, and fuel pump cartridge.
It started very well, but after running for about 30 seconds it had only about 1 quart of oil/water on the dipstick and the same mixture of oil and water on the ground. I checked the coolant reservoir and it didn't seem to have gone down much.
I don't think it was coming from the head gasket. It was coming out below the water pump area. This may sound like a stupid question, but can and water and oil mix then leak out quickly at the water pump if that gasket went bad?
