Its a longshot but didn't some mercs have combined coolant radiators and oil coolers? It might have only been some of the fast models, hence the oil cooler.

Well it could be a cracked block but gaskets are more common.

If it's just a bit of yoghurt in the filler cap, it might just be condensation. A long drive and a few burst of high revs should sort that out.

Dont think its a cracked block no oil dripping on the floor

Entirely depends on where the crack is. If the coolant and oil are mixing, it will be internal.

Yes, that sounds familiar to me. I believe it's a cooler for the auto-gearbox oil that is inside the coolant radiator and
is known to leak. We had a 2001 320cdi in with this problem (and a dicky gearbox). When the gearbox was repaired this
oil cooler was relocated so that it didn't happen again.

EDIT: Of course that means if you have oil in your water, you'll also have water in your oil. So you'll need
to remove that from the gearbox as well.
