I have my oil filter before the oil goes into the cooler and has worked fine for 400 hours.

Subject: [FlyRotary] What comes first; the chicken or the egg?


The Mazda manual shows the oil being cooled via the oil cooler before it is filtered.  One would assume that you would want the oil filtered before you ran it through anything.  Why did they design it this way?  What are most doing?  Are you cooling the oil before filtering or are you filtering the oil before cooling?  If one was to stick to the original design and utilize the original oil pressure outlet as the oil supply feed to the re-drive, it would appear that this oil supply to the re-drive is un-filtered oil although the oil is cooled.  I would assume that we would want filtered oil to the re-drive.  I am not sure how to tackle this problem.  Any and all input into this subject is greatly appreciated.
