Why Apex Seals Fail

Ok, so I have a few pictures of my own to back up Barry's Theory:

Naturally Aspirated application - 13.2:1 AFR 28 degrees BTDC Timing failed apex seal in front housing at 5400 rpm in 4th gear - after 37 seconds at WOT in road load simulation mode on Mustang dyno.

This happened a while back, but my camera was acting up.

Here are the Apex seals:

The housing in which the seals failed:

Another shot of the housing in which the seals failed:

Here is the other housing:

You can see that the seals failed exactly as Barry predicted.
