I've replaced the head gaskets, no cracks in the heads and no obvious external water leaks, so there must be some sort of an internal problem in the crankcases. The decreasing level of water in the radiator is matched by an ever increasing level of emulsified oil on the dipstick.

Has anybody ever experienced this problem before please or does anybody know a possible cause for the (internal) water leakage? Could it be internally corroded crankcases or is there possibly a simpler solution? Whats the best way to ensure sealing of the crankcase?

does your car have an oil cooler? i had a problem with an oil cooler mixing oil into my coolant.

I'll second that question. That's a very unusual problem in these cars.

no oil cooler... i think its leaking from inside the block somewhere.. making wrist pin pullers tmr at work, any suggestions on block sealant, for the two halves? - i used clear silicone last time and i think thats why its leaking... what do you guys use?

I use Permatex Ultra Grey with no issues. The sealant is not what keeps your oil and coolant separated though, the o-rings do. Also, if you did not install the little bolt for the lower coolant crossover, you may leak there.
