Can someone save me the research, please?  It would be very helpful to know when (200x) this changed from the a-few-flags to the many-teeth version.

Reason I ask is that I'm helping out a pal with an '07 GT that's really busting his chops, we just discovered a missing tooth (don't bother asking why - it's complicated) and knowing which years to scout the junkyard for would save us time+hassle.

 

AFAIK it varies depending on model and emissions equipment (California cars got it first).

It was about 2002, or so. Looks like some models switched over as early as 1999, but I know my 01 Forester has the older 6-tooth sprocket.

vs the 6 tooth:

FYI, EJ25D was '96-'99 and all had the 6 tooth. That LGT has an EJ255, SOHC 2.5s were EJ251s and 253s (and, occasionally, 259s).

Thanks.  Looking at the fit table on that first one, it appears that anything with a 2.5 that's '02 or later is a good bet.  The earlier ones are mostly 2.2 .

 

Why scour the junk yard? They are like $35 from Subaru. Just buy a new one.

1. Time.  As in, we'd like to solve this problem today.

2. The price you see in USD does not necessarily approximate what we wind up paying, all in, when it's headed for Greater Soviet Canuckistan.  The amazon link you provided doesn't even display a price.

(In case my link won't show you the price, it's almost $100 for a Chinese knockoff.)
