EOT meter for OEM oil cooler

Although the boiling temperature of water is 212F, your oil doesn't need to get quite that hot. Moisture in the crankcase will begin to vaporize at around 160F - 170F, and will exit through the crankcase breather.

That said, I strongly agree with all of reasons why oil needs to get hot enough to purge moisture. Starting a cold air cooled engine will send plenty of acidic moisture into the crankcase, due to the cold ring gap common to these engines (the gap closes as the engine warms up). Numerous cold starts without reaching normal operating temps will eventually result in a corrosive, white colored goo in the crankcase. If you ever see that, it's a clue that your oil is not getting hot enough.
