You had problems in that area before with NRS corner seals... maybe that was the problem.

The rotor can only go one direction... and parts of it may sweep faster or slower, but all portions are always going forward... rethink your position.

In a PERFECT environment, this is true...

You might find it surprising, and most of us live in reality...

Under less than ideal conditions, seals can resonate back and forth.
I.E. under pre-ignition and / or detonation

If you can guarantee that your engine will never see such conditions, then you would be right.
