Hi, there are no water oil exchangers if you find oil in the coolant in that m111 it is the head gasket that does not hold anymore and when the pressure rises the oil passes from the oil flow duct towards the head to the cooling chambers but not vice versa due to the pressure, that is why in fact in the engine itself you do not find other symptoms of water oil contamination. it is a common problem with these engines with age and mileage. Bye!
Generally the oil that passes when you have this problem on these engines is a small amount at a time, so the job does not need to be done immediately, but keep in mind that the oil around the cooling system softens the pipes and limits the dissipation of heat by the radiator, in short it is not the best
no because the gasket is not blown. simply on the m111 the seal in the head gasket of the oil passage gives way and due to the pressure you end up with oil in the liquid but the rest of the gasket is perfectly healthy, so you do not have the classic indicators of blown head gaskets from this problem. the result does not change you have to do the head gasket but the problem is not a "burnt" gasket
in any case, don't worry more than necessary, apart from the oil contamination in the liquid that comes up in the tank, doesn't cause any other problems, of course just think that sooner or later, when you want, you will have to do that job and that's it.

Would a sniffer test on the coolant tank - to look for exhaust gases when running - show if the gasket has gone or failing?
