djmark7 Posted August 3, 2007 Share Posted August 3, 2007 i know this has been discussed here b4 but i cant find it 1998 legacy 200k timing belt snapped while i was driving, didnt hear any big noise or chatter i didnt even know it happened till i looked at the tach what are the chances of no motor damage? i was driving easy at around 35-40 mph Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted August 3, 2007 Share Posted August 3, 2007 There is a good chance of bent valves and/or dinged pistons. However there is a chance that no damage was done. A cylinder compression test would help identify if any damage was done (of course a new belt would have to be hung on first). Unless you happen to have a 2,2L and if '98 2,2L was non-interference (can't remember off hand what year if any those became interference).

djmark7 Posted August 3, 2007 Author Share Posted August 3, 2007 oops yup its a 2.2 Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted August 3, 2007 Share Posted August 3, 2007 2,2L ok well that might be free-wheeling/non-interference, and if so, no damage was done. Maybe someone knows what year if any 2,2L's became interference? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted August 3, 2007 Share Posted August 3, 2007 nope, the 1998 2.2's are interference as well, so you're out of luck on that one. in 1997 MY all 2.2's were interference. a friend of mine has repaired a few and other than bent valves he hasn't seen any real damage. which isn't a huge deal, but it is significant labor so the costs escalate quickly. a couple dollars for valves....hundreds in labor.

idosubaru Posted August 3, 2007 Share Posted August 3, 2007 yes there is a chance, i can't give you a risk analysis or exact numbers, but probably a small chance. a mechanic should be able to do a leak down test. mechanics have those tools and they are easy to do, only requires removing the spark plug and moving the cam which is really easy...particularly since your belt is broke! leak downs are easy to do and can be done without a timing belt, unlike a compression test. these are excellent motors, if the vehicle is in good condition it would likely be worth checking.

djmark7 Posted August 7, 2007 Author Share Posted August 7, 2007 yay all is ok mechanic said you dont really have a problem with SOHC, DOHC is where you run into trouble Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted August 7, 2007 Share Posted August 7, 2007 I'd recomend finding a new mechanic because that is untrue. All subie motors since 97/98 are interferance and are equally prone to bending valves if a timing belt breaks. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted August 7, 2007 Share Posted August 7, 2007 The mechanic might be thinking there is no risk of the intake and exhaust valves colliding on the sohc, which is true, but on Subaru 2.5L's and any interference type 2.2L's (97/98+?) there is risk of valve to piston collision.
