haber rj,

Yes I remember the thing about the filters and the drain back valves! I made a mental note to use either GM stuff or Mobil1 M-207 filters. Mostly I use the Mobil1 M-207 filter and I can say that if I use the car enough I don't even get chain rattle on start up. Therefore I think that the mobil1 filter must have a good drain back valve. If the car sits for a week without use then I get the rattle on start up with either GM or mobil1 filters. I haven't tried any others because I can get the GM or mobil1 filters easily.
