Not really a performance mod, more of a maintenance mod, but thought I would put it here anyway. Thanks to Bopper and others who have done this mod in the past and mentioned it here on the forum, otherwise I am not sure I would have been aware enough do it, but glad I did. Thanks Guys!!

Fumoto F108 Oil Drain Valve.

Modified the threaded end with slots, 2-3 threads deep, to allow all the oil to drain out of the pan. It worked and I verified by letting the old oil drain for 2 hours, installing the new valve, and 2 minutes later opening the valve. A tiny bit of oil came out, so I know that the slots are going let all the oil out during a drain.

I used a pneumatic cut off grinder and put the valve in a vice, took my time to get them all as even as possible, and carefully cleaned up all the threads with a small file afterwards.

Note: If you do this, open the ball valve before grinding the slots to keep the grindings from getting on the ball part of the valve and possibly compromising the seal when opened. And obviously make sure all metal filing are removed from the piece before turning the valve closed.
