I screwed up the timing on my evo when I changed out the cam gears. I tried realinin to TDC but somehow that didnt work. HELP.

 

You need to set the crank TDC.

Then pull the belt turn the cams to tdc and poof. you should be 0 deg timing.

it might take some messing with the teeth on the belt to get everything to tighten up in place when you put tension back on the belt. If you lost timing I dont know any easier ways. The gears only go on one way and only have 1 mark tdc.

hope this helps.
