My Subaru died today, 1st time it wasn't my fault

[Alaska Style]

So I was puttin through town yesterday, not fast, just commin home. I was holdin steady 35ish, it jerked back, popped real hard out the tail pipe and the engine died. Dammit!!!! cranks over fine, just crankin dead. So I assume the driver side timing belt let go or slipped a copuple teeth which would throw the Distributer way off or not even turn it. The guy behind me herd the backfire and pulled over with me and helped push it to the back of a carwash parkin lot. I removed the timing belt covers to find out that the belts are tight, in perfect time, and look suprisingly new and fresh. I crank it a bunch and nothing happens. The distributer's tight and didn't spin. I'm thinkin WTF?. It pulses evenly and like it should by the starter so a rockers didn't fall off. "The exhaust rocker on my last Sub fell off". But it did run, so that wasn't it. I pulled the Cap and put my finger on the rotor and it easily spun around and I pulled it right off the shaft, YES!! FREE FIX!!!!! The weird thing is, There was no screw or anything under the cap that held the rotor to the shaft. I had a center consol full of options so I wasn't worried, I found an allen head that fit the shaft's threads so I enlarged the hole in the rotor with my pocket knife to make room for the fat allen's head. Put it on and it runs like a Subaru. I also found that one of my covers is cracked and who ever put the center cover on last rolled the rubber gasket around. I cleaned'm up real nice and put everything I didn't need to pull back on and learned another Subaru fix 1st hand

wow, lucky break on it just being the rotor, now the real question would be, what happend to the screw thats meant to hold it in place?
