952.2LX Posted February 27, 2014 Share Posted February 27, 2014 So i did a another nose job on my 95 2.2 lx . 340xxxx.... i forgot to tighten an idler and the belt flew off. Replaced everything and tried to restart and its off timing. Won't fire, even after alighning the marks. Where do i go from here? Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted February 27, 2014 Share Posted February 27, 2014 did a tab break off the crank sprocket or did the crank position sensor get damaged? Link to comment Share on other sites More sharing options...
952.2LX Posted February 27, 2014 Author Share Posted February 27, 2014 No I don't believe so. It all looked good when i put the new belt on. The first time when i forgot to tighten the idler the belt just came off and the engine stopped. Could one of the cams be 180 deg off? Link to comment Share on other sites More sharing options...
idosubaru Posted February 27, 2014 Share Posted February 27, 2014 (edited) more than likely you used the wrong mark on the crank sprocket. any check engine code? and yes check that the same or crank sensor weren't compromised during the flailing belt episode. should show up as a check engine code to if you scan it. if it's not that, the belt is probably just installed incorrectly or off a few teeth. the cam can't be off 180 degrees unless you don't have the mark lined up properly - you'd have to purposefully install the cam 180 degrees off - mark pointing down, but who would do that? 1. line up crank mark 2. line up cam sprocket marks 3. install belt 4. release tension 5. rotate to verify marks are correct it'll start Edited February 27, 2014 by grossgary Link to comment Share on other sites More sharing options...
952.2LX Posted February 27, 2014 Author Share Posted February 27, 2014 Ok, thank you very much i'll try again this evening. The crank sproket has a notch with a mark and should be lined up with notch on engine , correct? thats what i lined up to. Link to comment Share on other sites More sharing options...
952.2LX Posted February 27, 2014 Author Share Posted February 27, 2014 another question. Does it have to stay lined up? For instance if i tighten the crank pulley bolt and it turns the engine a bit. Would that cause an issue? Link to comment Share on other sites More sharing options...
idosubaru Posted February 27, 2014 Share Posted February 27, 2014 Ok, thank you very much i'll try again this evening. The crank sproket has a notch with a mark and should be lined up with notch on engine , correct? thats what i lined up to. there are two marks - use the dash on the very back of the sprocket. seen on the right in this photo: http://i48.photobucket.com/albums/f207/BigBadSubaru/0423091040.jpg people use the wrong mark often, the triangle at 6oclock in that photo i think. how the engine turns over is meaningless. as long as the timing marks are set - they are set, purely mechanical. it's not electrical or anything fancy, secret, or magical - the engine could never "know" that it was turned by: 1. hand 2. transmission (popping the clutch) 3. combustion 4. the starter it's all the same. it's all the same. it's very simple and nothing secretive or magical about it. with those three marks properly lined up - you're done, purely mechnical. nothing else matters. 1 Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted February 27, 2014 Share Posted February 27, 2014 and if any of those little tabs were broken off, you will need a new sprocket. Link to comment Share on other sites More sharing options...
