hello i was wondering if some of you engine builder guru's have some ideas what can be wrong with my 1.7liter W code motor i tryed calling brad roberts and jake raby but both didnt answer (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
so heres the dealio.. the case is together. cam is lined up correctly and the crank bearing pins are lined up (far as i can tell i did it 5 times!) everything was going fine and i was starting to torque the case half bolts and checking the rotating assembly. now there is a point in the rotation where it binds (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) flip it back around about 650-700 degrees and it hits the same spot. sitting there with a flash light i couldnt see any of the conrods or counterwights hitting the case or cam. so i undid all the bolts and nuts to see if it was just the case being tweeked but its not. now there is quite a bit of endplay since i dont have a flywheel on the assembly but i really dont think that will cause this problem with the rotating mass. so any suggestions? im going back out too the shop to play with it tommarow thanks...

dmenche914's logic is good. it is in that area but try it with the flywheel first before you tear it down. if it does not feel 100% RIGHT tear it down and inspect. you should be test fitting everything before final assembly anyway.
