January 25, 201016 yr My 1993 Subaru loyale had a no spark issue , i was able to find that the drivers side timing belt had broke. I replaced both timing belts and went to start it and the new belt broke. Is my engine toast. what would cause this new belt to break, is there something else i can fix?

January 25, 201016 yr The tensionor and oil pump sprocket spin freely.See if the idler spins freely. (A sprocket mounted to the engine body.) That what broke mine. Sam
January 25, 201016 yr Did you check and see if the crank/oil pump/cams are rotating smoothly? My first guess would be something is seized. I would assume you checked all pulleys before installing a new timing belt, so they should all be good right? the belt will slip awhile and the car will be driveable for quite a few miles on a seized pulley as the belt just slides around it, I doubt a pulley is breaking a belt right away. Did you install a belt and rotate the engine over by hand a few times? You installed the belt correctly (just making sure, don't know if you've ever done EA82 stuff before?)
January 25, 201016 yr Author Did you install a belt and rotate the engine over by hand a few times? You installed the belt correctly (just making sure, don't know if you've ever done EA82 stuff before?) What is the accronym EA82? No i did not turn the crank.
January 26, 201016 yr Author I havent checked but if the distributor gears were stripped could it cause the belt to break?
January 26, 201016 yr ouch! you should take off the valve cover and have a look inside. make sure the gear on the cam is intact
January 27, 201016 yr Author Okay, I took both covers back off, the crank turns pretty easily with a breaker bar on it, the oil pump, idler pulley, and tensioner all spin freely, and the distributor gears are fine. No Idea why the new belt broke... But I have put another new belt on and can turn the crank and both belts work great, but the car still will not start. I was looking at the Haynes Repair Manual and it says after you install the driver side belt to rotate the engine one full revolution or 360 degrees then align the valve marks and install the passenger side belt, is this necessary/required, if so what does it do? It is the only thing I hadn’t done previously.
January 27, 201016 yr Did you set the crank to the middle of the three marks on the flywheel/flexplate prior to installing the belts? These marks are nowhere near the ignition timing marks, FYI. Did you install belts with one cam up (passenger's) and one cam down (driver's)? If so, you have other issues. Was the car running fine when the belt broke? If yes, then the belts are not installed properly.
January 27, 201016 yr Author I aligned the crank to the three valve marks, not ignition timing as stated, but the it says to put both cams up matched to the notched mark in the timing cover case, that is why i was asking about turning the motor 360 degrees after installing the first belt The car was running fine when the first belt broke.
January 27, 201016 yr You should check out youtube and search for miles fox. He has a video series for changing the timing belt. It's a short video and shows what needs to be done. I would check those out and see if you have missed anything according to the videos... Just a thought. Oh, and a shameless plug for Miles Fox's videos too. They are fantastic I found the link for the timing belt video http://www.youtube.com/user/MilesFox#p/u/14/ZG1p70E4VXc Good luck!
January 27, 201016 yr the haynes book will throw you off with the pictures of the cams up. Yes it shows both cams up, but the body of text describes rotating the crank 360 after instsalling the first belt line up marks, install first belt up. rotate crank, first cam faces down. now install second belt up, rotate again, then find odeg and install the disty. do a search for " EA82 timing belts" and the link to the timing belt article will be thrown all over the place:grin:
