I'm replacing the timing belt on 05 WRX and following instructions I printed off FSM as well as a couple of other replacement directions. Prior to taking the old belt off I lined up all the timing marks on the crank as well as cam sprockets. After getting every thing in place with the new belt on I didn't think the crankshaft mark was lined up as good as it should be. I removed the old belt and moved the crank to try and line the marks again. I felt some resistance and stopped. I turned the crank clockwise. I'm now thinking this wasn't a good idea to change the crank position. In any case I need to find out if anyone out their can help me to get the crank mark back to where it should be. I'm not sure if I need to turn the driver side cam sprockets back to where the marks line up and then turn the crank or what. Also it is my understanding the cam sprockets on the left did not have tension on them, but what about any movement for them in trying to get the crank marks lined up again.
From what I've heard about the left side (passanger) when changing the Tbelts, it will appear that it will be half a tooth off... When in fact is in possible cause your either dead on or a tooth off, so if it doesn't look dead on on that side your actually are...

Yes... you need engine management for engine modifications
Thank you for the replies to this. I went through the change steps and had the new belt on and then felt the crank mark on the engine and the others on the crank were not lined up good. I removed the new belt and without a belt on the engine I turned the crank in an attempt to line the marks up better on the crank and block. After rotatin clockwise possibly half around I felt resistance and stoped rotating. I need to find out how I can get the crank back to the correct position again and what I need to do to do this , like do I need to line up the driver side camshaft pulley marks and turn the crank or what do I do.
