can any one help ? myomega v6 3.0 keep emptying its expanshon tank of water have to fill it every day iv put cardbourd onder the engine bay to see for leeks their are non ?

What, does the water come out of the expansion tank ro you're topping it up? I think a few common areas for leaks on the v6 is the heater bypass valve, under the scuttle on drivers side. Quite cheap and easy to do, just a little fiddly.

The oil cooler in the centre of the V under the plenum, or right now mine is losing it from the water pump after only 5500 miles (albeit a small leak).

If there is no sign of water it could be the oil cooler area as it could evaporate before hitting floor.

Other members on here have suggested that the head gaskets very rarely fail so unlikely to be that, although I have no personal experience of that.

How quickly are you losing water?

Have you had any work done recently? Are all the hoses/pipes etc secure?

Yes there is you just have to find it. Over and above what Geoffr70 suggests check that the expansion tank itself, been known to crack, also check you carpets in the front for damp.
