mercuryrising17 Posted October 20, 2011 Share Posted October 20, 2011 Im a noob and just have one question that I cant find. I have a 2002 legacy gt limited with the 2.5L sohc engine. Is this a non interferance engine or an interferance engine. I would guess that is a non interferance and that I can screw the heads up to bad but though I would check first. Thanks!

johnceggleston Posted October 20, 2011 Share Posted October 20, 2011 ALL 2.5L engines are interference. waht are you trying to do? Quote Link to comment Share on other sites More sharing options...
bhazard Posted October 20, 2011 Share Posted October 20, 2011 Its interference and that means you can bend valves. I think you had it the other way around judging by the last sentence in your post. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 20, 2011 Share Posted October 20, 2011 If you are referring specifically to the intake and exhaust valves, you don't have to worry about those hitting each other in the sohc. They could hit the pistons though potentially. It is possible that the 1996 Subaru 2.5L dohc may have been a non-interference Subaru engine piston to valve.

mercuryrising17 Posted October 21, 2011 Author Share Posted October 21, 2011 I put new head gaskets on and I am to the point of puting the timing belt back on. this is my first time doing something this big and I am just real nervous about messing something up. I have the timing belt on but there is still just a little slack in it, not much but it probably moves up and down about a half inch. I have not pulled the pin on the tensioner yet so i think it will be fine when I do but like I said its just a little nerve racking since I have never done this before. I really apreciate all of your help on this website it has been great for those times when I second guess myself. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted October 21, 2011 Share Posted October 21, 2011 review the pic below and time it correctly. using the wrong timing marks can cause bent valves. DO NOT assume you can identify the correct timing marks just by looking at the cam and crank sprockets. YOU WILL GET IT WRONG unless you know what you are looking for . study the timing ''alignment marks'' before you pull the pin.

mercuryrising17 Posted October 21, 2011 Author Share Posted October 21, 2011 Is it true that you want the left(driver side) cam alignment mark to be slightly to the right before you pull the pin due to it moving slightly backward after pulling the pin?

mercuryrising17 Posted October 21, 2011 Author Share Posted October 21, 2011 Ok thanks. One more question then. Will the white mark on the belt stay lined up with the timing Mark on the sprocket so that the line and the mark are slightly right and then :burnout:will move back. Sorry for all the questions but I appreciate your help Quote Link to comment Share on other sites More sharing options...
987687 Posted October 21, 2011 Share Posted October 21, 2011 Have the line on the belt and the line on the sprocket perfectly lined up. Even if the belt stretches or whatever, the line on the belt and sprocket will stay unless the timing jumps. The sprocket will move a little bit in relation to the timing mark on the belt covers though, so yes, the sprocket will turn a little when the belt takes up tension.
