Oil draining over the hot exhaust? Sounds good guys, let's sign it off and start production!

Seriously, couldn't they just extend the tube a bit so it overhangs the exhaust pipe???
Plastic would be a bad idea, but there's a company called Fumoto that makes a ball valve replacement for the drain pan plug that has a hose barb on the end.
I can't recommend them enough.
