I recently installed an Amsoil bi-pass filter system on my '03 H. O. Six speed and am experiencing an RPM-related "growl". Both oil lines are routed cleanly and are not in contact with engine parts.
Amsoil suggested checking to make sure the inlet and outlet lines were connected correctly, which they are. Could the bi-pass valve be defective? Any Ideas?
