Is there anysigns of leaking, sounds more like HBV if it happens when driving, especially if you have aircon/heat on.  may be worth having a feel round the back of plenum where HBV is situated

Still think there should be an HBV for the water to circulate around the heater matrix.  May be wrong though.  Can you update your profile with car etc.  Stops everyone from asking the same question about what you drive.  Thanks

Had a similiar prob with my V6's both had same fault. the water pipe at the rear of the off-side head had holed but only seemed to leak when revving the engine if let to warm up at tickover it didn't seem to leak.

hbv got to be first place to look, my car on at least its second in 70k, see guide for location and next time it leaks, see if the bottom of it is wet...

Update your profile mate then people can see which omega you have, 2.0, 2.2, 2.5 etc

No aircon = no HBV, I do believe.  Ours doesn't have one.  I know 'cos it's never leaked.

Could be a small hole in the radiator somewhere.  My old volvo used to keep its water until you stopped the car.  The hole would then expand and drop the lot in a one-er!  First thing you need to do is get your head under the car and find out what area it's spilling out from.
