there is no oil in the coolant, its a clay like material, oil in coolant become blobs of gel - which I have none.

I have also seen cracked blocks mix oil in coolant but it always works the other way too because the hot coolant stays pressurized even with engine off - thats when it mixes with oil if the block is cracked.
