Yes, thanks for correcting my spelling as well as the suggestion. I see your from Cincinnati, Hope your not still sore about that wild card game. LOL. I agree with the silicone anti drain back valve. That's one of the reasons I chose the fram ultra. I will try another mobil 1 filter though to rule out that the filter is causing the noise.
