Roger, looking around, I found this on a Jalopy Journal post. This came from post #27.

The oil pump pickup screen has a strap across the middle. Sometime when you find an old screen laying around, take snips and cut the strap on one side and pry up the strap. Under the strap you'll see a hole in the screen, usually finished with a stamped ring around the hole that is meant to seal against the backside of the strap. The intent is that if the screen gets clogged with sludge suction will pull the screen up and allow oil to get to the pump thru the hole.
Get that engine in a high rpm situation (maybe a kickdown to a lower gear in a passing mode, etc.)with a partially blocked screen and it will pull the screen up and any debris present (chunks of valve stem seals) will get sucked into the pump. Then what we see here happens, although I've never seen one twist so symetrically. Learned long ago when touring salvage yards in search of a rebuildable SBF core that the next thing to check after visible damage or missing parts was to pull the distributor and check the oil pump drive shaft.

BTW, was that a high-volume oil pump?
