Just checked again and dipstick seems fine (Engine cold) last time I checked it was hot and felt oil looked lighter but thinking I only changed the oil 5 weeks ago.......... water seems normal but there is no puddle of water on the floor only a puddle of oil 

Ok so water in the oil then, that's good news. Water does not have oil in it as you say it looks normal, that's good news too.
As regards to the water leak.. leave the heaters on hi and see if the water leaks. Then try the heaters on lo see if again the water leaks.
When the car is hot can you smell water at all or even oil? Where abouts on the floor are the water leaks and oil leaks when they happen?

Is it possible you could have two separate leaks? I had two leaks recently, similar drive mess, in this case the coolant was leaking from the water pump and the oil from the cam cover seals, all running down the block and ending up in the same puddle! My V6 is within a few months of yours and that is the first time both the water pump and cam cover seals have failed. Both replaced and all is fine now.

Right the leak of a mix of oil and water is coming round the gear box bell housing where it joins the engine and dripping of the bottom. plenum is now off and hbv looks fine no sign of water round it, however when heating is on max the drip turns to a solid stream and no hot air in the cabin, looks like there is oil in the V so suspecting cam cover gaskets not sure where the oil is mixing whith water though it is a good mix though not streaky as if water was being sprayed onto oil,
Anyone fancy doing my camcover gaskets as i done these about 3 years ago and seems they have failed

Description you have given of oil/water mix appearing around gearbox engine joint would indicate leak is from the V of the engine.

Only thing there that would mix oil/water is the oil cooler but the plate seal would have also gone to cause it to drip down the back as it normally stays contained inside the water chambers.If you have no heating it might be the matrix is gunged up with oil/water mix and will need a thorough flush through as well,although this would all be pretty normal if cooler has gone.

Think you need to get the entire top end stripped down to see what is going on with the oil cooler /plate seal.

Would suggest NOT running the engine any further as you will just be pushing more muck around.

Plenum off, inlet manifold off..... Rain stopped play  car going nowhere

If that oil soaked piece of kitchen roll has been dipped in the header tank ?.............your oil cooler has sprung a leak.

[OmegaGav]

The left hand side has been dipped in the header tank the middle of it has had the dipstick wiped on it and the right side end is what i wiped of the floor !

Would be worth pulling both quick fit connections off bulk head heater matrix join to see if they leak just coolant or the same oily mixture.

That would then give you a clearer idea if gunge has blocked up the heater matrix ,hence the NO heat issue.It does look like an oil cooler issue but you may have caught it before its gone too far into the system although will still need flushing through.

[OmegaGav]

Oil cooler was my initial thought but what is confusing is there are areas of clean oil in the V and the floor then the water oil mix running round the bell housing/engine joint Is it possible for the oil cooler to push clean oil up into the V and also leak the oil/water mix out somewhere else ??

[amba]

Oil could leak out of either of the banjo bolts that hold the feed pipes..they are sealed with a ali crush washer on either side and torqued to 30nm.

Suppose they could be leaking oil and if HBV is alos playing up the stream of oil might be taking the same route to earth as the coolant so appearing as a mixture .Would have thought oil leakage from the banjo bolts would be pretty conclusive if you are stripped down to the cooler plate.

Possibly coolant could also be leaking from bridge and mixing the same....needs totally stripping down for a really good look....pictures if possible might aid us further with online diagnosis
