Coolant Temp?

Further to the info that JFP noted, if the coolent never gets to ~180F, then the oil never gets near 212F and the water tends to stay in the oil.

That is not completely correct. The oil system in the M96/97 normally operates under about five inches of vacuum (to afford better low tension ring sealing), where water boils well below 212F. Add in the fact that normal oil temps are always higher than the coolant temp, and the water is easily removed under normal driving. UoA's before and after going to a 160F stat have confirmed this.

JFP - thank you, I was not aware of this fact. I learn something new everyday around here!
