Timing belt pully interchange 2.5 to 2.2 / Cam Sensor?

1. first is definitely to simply pull the p/s timing cover and look at the timing mark. is it lined up perfectly when the crank mark is lined up? it's only 3 10mm bolts to remove the timing cover....or none if you leave the covers off like some of us.
2. might be able to pull the plugs (if they're relatively new) and compare sides, if the passengers side is notable different than the drivers side then that may suggest compromised timing due to the sprocket change.
in the end those timing belts are actually not that hard to do - i can do that in about 45 minutes, and they generally come apart easy if they were just done, but i've done a bunch.

Have you tried cleaning the MAF sensor? Checked for vacuum leaks? How old is the gas in the tank?

Hey - Thanks for the input guys... Just to put this topic to bed - it ended up being a burnt valve... compression was 70 lbs lower in no.1 cyl. plus a little oil ... intermittent miss. 30k miles later, still running on the 2.5 timing pully

nice, good follow up!
did you repair the burnt valve?
What ended up happening - did it get worse or...?
i wonder if the wreck slightly bent the valve and "caused" the valve to burn?
if the wreck was hard enough to bend the pulley then maybe the timing was affected.
generally 1996 are non-interference engines, but there have been cases of 1996's seemingly verified to be the original engines - that incurred valve damage. there's one documented well on subaruoutback.org.
