2001 Peugeot 307 Water Leak

Engine Cooling problem
2001 Peugeot 307 4 cyl Two Wheel Drive Manual 90000 miles

We have a Peugeot 307 HDI which has a mystery problem.
9 different mechanics have looked at the car and the water pump has been changed but the warning light to top up water coolant keeps coming on every few miles.
There is pressure in the header tank even when the engine is cool and water is escaping from here when the engine is under pressue.
There is no foam or water in the oil, no white smoke from the exhaust so it can't be the head gasket and has been pressure tested so all seems fine in that area but STILL we have this problem. Do you have any clue as to what this could be please?

Do you
have the same problem?

Hi there,

I would get a head check done, thi sis a quick & simple chemical test fore exhaust gasses on the cooling system, this will prove if the coolant loss is internal, start here.
