HELP!!! crank wont line up to TDC!!!
if you are asking these kinds of questions and having this much problems, you should not have attempted this kind of job. timing belts are tricky and one mistake can cost you hundreds or thoousands of dollars. if i were you i would try to find someone with the knowledge to do this kind of job to help you with your car before you destroy your engine.
Honestly best bet at this point is just pull out the cams, line the everything up on the bottom end, put the cams back in, put the belt on, and do a compression test and leakdown when done. Hopefully if you didn't try forcing the crank around you're valves might still be ok, after that the tricky part is making sure your oil pump and balance shaft are correctly lined up.
You guys are getting closer...lol..
Here is what you do. Its pretty hard to bend valves by turning the engine over by hand. If that was possible could you imagine what just one small explosion would do to them?
Anyway stick a long screw driver down cylinder 1and cylinder 2. Turn the engine either clockwise or counterclockwise whichever way you are able to until the screw drivers are about the same height. What you are doing is trying to get the pistons half way in its stroke. When you do this all four cylinders will be in the middle of there stroke.
From there turn the camshafts one at a time until the dowel pin is at the 12 o clock position. Do the same for the other camshaft. Now turn the crankshaft until you reach TDC. At that point do the normal timing belt installation.
Good Luck!

EDIT: Guys there is a reason why im telling him to do it this way. Whether he listens to me or not is his option.

Ok at this point what if both your cam dowels, crank dowel, and pulley to the right of crank(oil sproc ?) are all at their respected marks and all 4 cylinders are even across the board mid stroke. Which cylinder needs to come up to TDC. 1 and 4? Yes i am a noob...
i got my gsc s1's installed and mine was just a little bit off from lining up perfectly with the hash marks.. is it suppose to be a true tdc or is it all right if it's just less than a tooth off? that still bothers me from time to time and was jus wondering about it.. wat kinda bad things can happen anyways if them hash marks don't line up?? lmk guys, thanks.
This is no help to you now but for the rest of you readers .... start off with everything lined up with its respective timing mark. Once the belts are off the cams will move and when working on the engine it is easy to move the other sprockets too. So, before you pull the belts, paint marks on the edges of the belts and extend them onto the sprockets. With the belts off, transfer these marks to the new belts. This is easy to do if you stack the new and old belts. Now, with the new belts on, if you haven't spun any of the sprockets, when the marks on the new belts align with the marks on the sprockets, once you get the tensioner adjusted correctly (very important), you are good to go. Without doing this the timing marks will often look ½ to one tooth off until the belt is tensioned. This can cause endless frustration. Get the cams a tooth off and the engine will lack power.
A note on the harmonic balancer....DSMs used to break the rubber in the balancer on a regular basis. This allowed the outer pulley to rotate and eventually come off. I haven't read of Evo's having this problem but there is always a first time, If the outer pulley is moving the timing mark isn't going to line up.
