Question about 2006 Fiat 124
Water is lost two ways.. leaks in the nomal routing of the cooling system.. and leaks into the piston or intake.. where it then goes out the tail pipe.. sometimes in the form of vapor... even small drips.
It probably leaks more at a certain operating temp then others.. drive time etc can affect the rate of loss.. but like any water leak.. it never gets better... only worse.
The garage should have done two things.. check the cooling system for leaks.. and check engine compression. Sounds like they did both.. if the head gasket has a small leak again it will only get worse over time.
If you are not finding water under the car.. or inside the car (heater core leak).. and you don't smell anti freeze.. chances are it's the head gasket.
The trick in finding a leak you can't see is taking it someplace that has the proper equipment.
A "block tester" should be used as well as a standard pressure tester.. there are many places coolant can leak.. hose connections, water pump, heater core, intake manifold gasket, head gasket and even a cracked block.
If they are detecting water in the oil.. or when you remove the oil fill cap and see a yellowish foam or the oil looks odd on your dipstick.. you probably have water in the oil.. confirming a head gaset leak or worse.
Have it retested (pressure and block tester) at a reliable shop.. or ask the fellows who made the first diagnosis how they arrived at it.. in other words.. what test(s) did they do.. inpsect the oil.. pressure test.. block tester etc etc.
Best of luck
