The Mazda manual shows the oil being cooled via the = oil cooler=20 before it is filtered.  One would assume that you would want the = oil=20 filtered before you ran it through anything.  Why did they design = it this=20 way?  What are most doing?  Are you cooling the oil before = filtering=20 or are you filtering the oil before cooling?

The = passages in the oil=20 cooler are huge by comparison to bearings in the engine, so it = makes better=20 sense to filter the oil just before it gets to the oil passages in the=20 engine.    

If one was to stick to the original design and utilize = the=20 original oil pressure outlet as the oil supply feed to the re-drive, it = would=20 appear that this oil supply to the re-drive is un-filtered oil although = the oil=20 is cooled.  I would assume that we would want filtered oil to the=20 re-drive.  I am not sure how to tackle this problem.  Any and = all=20 input into this subject is greatly appreciated.  

Many of = these oil filter=20 adapters that have recently been pictures have threaded outlets for = pressure=20 and/or temp sensors that are after the filter.  These can be used = for the=20 redrive supply.  The 13B has a port on the top, plug side of the = front iron=20 housing, that can be used.  I'm not familiar with the Renesis, but = I'm sure=20 it's got something that can be used.  

I don't = think this will be=20 your biggest problem :-)

Cheers,

Rusty =  =20
