I'm currently using an AC PF 24 but would like to use one with anti drain back valve. Any suggestions? 66 GS 401
Hi-I 've heard this kind of request before, but not too sure I understand it. I had an RX-7 that the filter was mounted upside down and a number of cars that the filter was horizontal-I'd want the anti-drain valve on those applications, but with the way the nailhead filter mounts, how could the oil drain anywhere?
