what kind of oil coolers are people using for the 0-320 ? Apparently my right oil cooler is larger then the left and the LAME's detected a crack in it...
Are some better then others?

Gerard,

 

Two oil coolers?

 

I have a 7-vane Stewart-Warner on my I/O 320 that requires the oil cooler air intake door be partially/fully closed in -10C or colder conditions.

 

Look at:  http://www.oilcoolers.com/Default.htm

 

for some cooler information, especially SW performance data.
