Perhaps safe to assume those RX7 filters do Not have ADBV ?It's not much more messy draining my RX-7 like this, than putting a hole in the filter. lol Depends on how much time I have to do it really.
If I have the time, then I'll just crack open the oil filler cap (where the oil goes in the motor) and then open the drain plug and let it set for awhile.
Later on, when I finally take the oil filter off, there's not much more oil there than if I use the screwdriver and hammer on it.
