I got rid of the clicking sound that was coming from the sandwich plate by replacing it with the Mocal sandwich plate.

About the other sound. it's obvious that other engine oil cooled cars don't have the sound we have. my only novice explanation is the sound mite be normal and the bigger PS cooler just magnified the sound of the normal operation of the power steering, Or there mite be a stress on the Power steering it's self from the added cooler.
