Ok! soooo i never really noticed this b4 but at start up my engine does this like knock/ tap thing. Now iknow what a knock sounds like. Its kinda like a knock but a hell of alot softer if that makes any sense what so ever. i tried seafoam on the top end just to see what would happen i idle alot better but the tapping is still there and its comming from the bottom end. im a little worried at this point.
so im going to try to seafoam the cranck case and ifthat doesnt work start looking at replacing the bearings and wristpins i really hope i dont have to replace that stuff. but when duty calls what you ganna do i guess. any imput would be great weither some one had this problem or are farmiliar with it.
