For true. I learned the hard way, use the cap which matches the filter. In sixty-seven years of changing oil, this is the first time I've run across name brand aftermarket oil filters being sufficiently non-compliant to cause major problems. WTF???

Buy yourself a STC fitting kit from a Ford Dealer. If your EGR cooler is still present, you'll need an EGR install kit too to make sure you don't have any leaks.

I had a couple hours to charge up the batteries and get into this again. Attached is a photo of the CTS during cranking, it took 13-17 seconds to show low oil pressure on the dash gauge… Again any input is appreciated
