Okay, here is the scoop. About a month ago I had the timing belt jump a few teeth when the car was cold. I had started and stopped the engine very quickly. I re-timed the engine and all was well until Saturday while I was putting in a new tranny (manual) While messing with the crank to get the tranny to go in to the clutch, I heard a pop and when the engine started it ran like crap. I pulled the covers off and sure enough the belt had jumped again. It looked like the tensioner wasn't holding enough tension, so I replaced it with subie tensioner. Well, today I was going to my friends shop and I down shifted to pull into the driveway and the engine died. It sounds like the timing jumped again. I will probably look at it again tonight. All of the idlers are new as of a year ago and they all move smoothly. The tensioner I put on Saturday was tight. Do you guys think it could be the belt itself? Any thoughts would be greatly appreciated. Thanks

Mike

Oops. It is a 2.5 DOHC motor and I know that it is an interference motor. I am praying that no valves got bent today.

Could be the belt is stretched. Did you change it after the first occurrence?

 

The first engine in my old '99 OBW (now my son's) died of a seized camshaft. Hopefully that is not what's happening to your engine.
