Is water getting in the oil, or oil getting in the water? Done a compression test? V6 Head gasket failure is very rare, I've only seen it on one Omega ever.
What year, and engine size?
If you do need replacement heads, I have some of a prefacelift 2.5 going cheap... but hopefully (for you) you won't need them...

Anyway,as prev said unless you have water getting into the oil i think it is the oil cooler. regards Gary. :y

On 4-cylinder engines, i.e. 2.0 8V, 2.0 16V, and 2.2 16V it is not a huge job. A memeber here had his done for around £350 by a mechanic after being quoted around £500 from an independent. Vauxhall would probably charge £1000+.
On V6 this is a big job, access to remove the heads is not good so very work intensive. In my opinion on a V6 this paying garage money would be uneconomical, so only makes sense really as DIY.
Having said that, as mentioned above head gasket failure is rare on the 4-cylinder engine and even rarer on the V6.
The V6 has an oil cooler which often fails giving symptoms similar to head gasket failure. As a rule, oil in water is oil cooler, water in oil is head gasket.
Check for exhaust gasses in the header tank (at a garage or MOT station), and also carry-out a compression test.
