Re:Drain plug vavle!
 

I have been using one that Aeroquip makes. It has a quik release couple that starts draining when the drain tube is plugged in.

I took it out for two reasons, it reduced the ground clearance a little (I could tell by the marks on the thing), and it takes way longer to drain the damn oil because the hole is smaller.
