Default timing belt issue

its been a while since i have posted here.... this is the situation.. sold house. building new one.... gf pregnant... car (2002 wrx) with 215k on it.... dont have a garage and dont want to go to a stealership right this second...

looks like the timing belt jumped or something failed... blew out and shattered what looks like a large plastic gear. i am no really sure. i havent spent much time in this engine. is this an interferance engine? why did subaru make part of the timing belt(whether it is a cam gear or some other part of the timing belt) plastic...even if it is a pull.... what the ****....

is my engine done?

yes, its an interference engine that has VERY little tolerance for screwing with the timing system... It would be highly unlikely that you didn't destroy valves/heads/pistons/cylinders.

Obvious question is when was the timing belt changed last? What else was changed?

Yeah, the timing sucks, but think of it this way, she had a good run at 215k miles at least!

In my case my a cam seized, causing the cam gear to assplode. I ended with one shot head and just about every valve bent on both sides. No visible valve to piston contact.

yea biodude.... thats the **** that exploded.. i dont know what happened or why, havent had time to look and i wont until feb or march...

i did the timing belt at around 140k... replaced belt, tensioner, water pump.. thats it.. tensioner was fine, but i replaced it anyways.. everything else looked great. i mean the belt itself was not missing any teeth at all, and wasnt stretched that bad....

here was the source of my problem, the gear exploded because when the cam locked up, the timing belt pulled tight and took out the cam gear.

Sorry to hear about your problems. Chances are that the valves got damaged to some extent. I would take it somewhere and have them checked you may have got lucky but, chances are if it was bad enough to break the pulley then the valves are damaged.
