ok guys i think im screwed. i bought a d16z6 motor, trans, wiring harness, ecu, and axles a couple of weeks ago for $400 from a guy here in town. it has ran fine till now. when i get above 3500 rpms it starts ticking. now i know hondas tick a little but this is pretty loud. it almost sounds like its knocking. my dad thinks its somethin in the head.(which i hope it is cause i can get one for cheap) but ive got a bad feeling its got a bad wrist pin or it spun a rod bearing and its knocking. anyone had this happen???? thanks!!!
