I would print of this thread,take it to the mechanic,demand return of car (if he still has it) and all money paid thus far.If he wont agree - trading standards,small claims court etc.
This type of thing makes me rather angry.

Thats a very bad mechanic and a very bad diag!

So far hes spent a big wedge of cash based on poor information.

As a pointer, lets consider a cylinder head face:



The above is a V6 head although most cylidner heads on modern vehicles are similar.

The blue areas are coolant passages, under normal running, these are pressurised but drop to approx atmosperic as the engine cools down.

The brown areas are oil retrun passages where the oil drops back to the sump. Thanks to teh breather system, these are under a slight vaccum (assuming breathers are not blocked!).

The small red area is THE only place where pressurised oil passes and is nicely away from anything other than the head edge. This is proteced by a copper insert in the gasket.

So to get oil in the coolant via a failed headgasket we need the strongest bit going (basicaly a copper O ring) to fail and the oil to travel a reasonable distance to the water.

Now if the heads were to crack it would most likely occur around the valves, this would potentialy allow the coolant into the combustion chamber but certainly not the oil.

Clearly the person doing the work thus far is lacking a grasp of the basics!

For this scenario, the actual answer is a failed oil cooler which is around three hours work and around 150-200 in bits.

NICELY WRITTEN AND EXPLAINED POST!!

I must agree with Omegatoy. 

Somewhat off-topic: it's quite surprising (to me anyway) that the high-pressure oil feed to the cams and lifters goes up into the head round the outside of one of the headbolts. My Golf is much the same.  Hardly anybody would believe me when I noticed this.

Very common, one less hole to drill!

Even my old 1959 Dexta diesel engine has the same!

Hehe, thanks for clearing that up, I assumed a simple explanation like that would apply.  Assumptions though...
