I with Roland, as the slippers are ripped off the pistons.
But only one could of let go, or a different malfunction occurred and it self destructed.
Many times it is difficult to really know which came first, the chicken or the egg,
so to speak.
Sometimes we just have to understand some things we will never know the underlying cause.
We could guess till hell freezes over and might not guess or be able to prove the straw that broke the camel's back.
Just too many variables is my opinion

One thing is certain, it "done blowed up" as they say in NASCAR.
