Re: PF970C AC Delco Oil filter
The filter thing is a big running debate for these cars. It seems like it changes which is the best as far as the anti drain valve from year to year. As I recall, Mr. Haibeck said the current one to go with is the current blue PF970C.
I got a handful from a guy on ebay fairly inexpensive a few months ago. I think I ordered 3 figuring that'd last a while, but now it looks like I'll have a second Z to maintain.
