my brother was bothering me to change it and i kept putting it off...well the damn thing snapped when i was in some hoodie area and not only did i have to replace the belt and water pump, but i fawked up cylinder one! i would check to see if you have any internal damage! now im looking to either go ls/vtec or built an ls head! im leaning more towards building an ls head right now though! good luck anyways.
