Any guesses why it left me stranded?

Update from the shop - he pulled the oil pan and did some looking around and he's quite convinced it dropped a valve and then the engine grenaded from that. He said not due to oil starvation. He's not sure (nor am I) as to what would have caused a valve to drop. In 7+ years, that engine was only redlined once and that was for a nano-second and was probably 4 years ago. The morning this happened, i was passing a car on the highway, but was definitely not exceeding 5k rpm's during the couple seconds it took to pass the car. As i said earlier, it's always been babied ... maybe too much.

Also, the flex plate it toast, but other than that, the shop says my Z should be ready possibly be end of day tomorrow.

Any guesses why valves decide to drop themselves into a cylinder?

We'll update when i get my Z back.
