I have a boss 302 “oil cooler” on my engine block and it requires the FL820 Ford Racing oil filters. Have done a half dozen oil changes the last year between track days and never noticed this gap until today. It has me worried but I think I’ve just never seen it at this angle. The threads are perfect, goes right on like normal, and as soon as the rubber gasket makes contact it becomes harder to tighten which is completely normal. However, the lip of the oil filter does not touch. There is a gap between the edge of the filter and the cooler/housing.
I tried two new filters to be sure, and the old one, and they all have this gap. Did I just not notice it before? Started the car and revved it and no drips. Just concerning.
I am 100% certain the old gasket came off with the older filter, and that it’s not a double gasket issue on the filter or housing.
