Question 2.2L (EJ22) 1997 OBS Interference or Not?

Has anyone out there had their timing belt fail on the 2.2L engine? If you have was there any valve/piston damage?

Lots of conflicting claims- from message boards, web sites, and dealers- that the 2.2L is or is-not interference type. SOA says this:

Dear Mr. :
I have consulted with our Technical Services Department who confirmed exactly what I relayed to you. I can offer you no more assurances than the fact that you have written Subaru Headquarters, I looked up the specifics of the engine on record, according to the VIN you supplied. According to our records, you have a 2.2 liter engine, 1997, which is a non-interference engine.

Best wishes,

Please no " I think it's this..." or "I heard that..."

Looking for first hand, factual information regarding the 2.2L engine.

Driving Very Cautious,

According to the 1997 Technical Referance Booklet;

"Compression has been increased to 9.7/1 by reshaping the crown of the piston. This eliminates the clearance that was available between the piston at TDC and a fully open valve "

I have never seen a broken Cam Belt on an EJ motor. I have seen a few that changed timing because of tensionor or idler problems.
