This is the scary gray area. I totally understand that if I install an aftermarket cooler, and it blows an oil line, loses pressure, and destroys the engine before I notice and shut it down, that's not a warranty repair for Nissan. What I'm afraid of is when I install an oil cooler, and something goes wrong with my VVEL 10K miles later due to a factory defect that has nothing to do with oil temps, and they deny the claim because an oil cooler was attached to the engine.
