Just getting done changing out the rod bearings (Ford mounts in soon) on my GT and was looking at the oil pickup.
Wonder why the pickup has a cup on the back side that fills with oil and only one drain hole on the side to let it out.

 

The cup shape fits in between the four vertical walls coming up from the floor of the oil pan. It extends up and fits in between those four walls to help prevent oil from sloshing around from one side of the sump to the other during cornering, braking, and acceleration. Just having the one drain hole in the cup isn't a big deal. If the oil can't drain fast enough out of it, any additional oil just overflows and goes directly into the sump that way. Having more or larger drain holes would reduce the effectiveness of preventing the oil from sloshing back and forth. It would just slosh back and forth more through the holes from one side to the other.

 

I understand using the cup as a baffle, buy why open top?
