Chrissi,
    My own opinion is that after warm up and in = flight the=20 oil temp leaving the engine before the
coolers (air or water  to oil) will almost always be well = above=20 160-180 F..............If it is not this
high then the oil to water cooler will actually help warm it to a = more=20 efficient temp.........IMHO
 
   Somebody correct me if this is a fallacy=20 !!.......................<:)

Subject: Re: Fw: [FlyRotary] Re: = Fw: Water=20 temps

This is where I get confused:
 
said previously,
-ideal water temp =3D 160*~180*F
-ideal oil temp =3D 160*F
 
If we are cooling oil with water that is at best hotter than the = ideal temp=20 of the oil, then are we not adding heat to it rather than removing it? =
 
If we are trying to cool oil, why would we feed the highest temp = water to=20 the oil/water cooler rather than the coolest temp water by tapping into = the pump=20 housing where it enters the block?
 
Based on feedback, the water entering the block may be as low as=20 150*~160*F, would this be cool enough to do an adequate job of cooling = the=20 oil?
 
Also, which model of Mocal is being used?
