? about knocking in motor

[scottwalker]

i have a 91 explorer and i have done redone all the gaskets and rod & main bearings and all of the top end and i still have a knock in the motor some shops said its the timing chain is it posable? i have dumped to much money in it and getting tired of going in the motor

post a video of this knock your talkin about. the timing chain will "rattle" if there is a problem. It wont be a "knocking" sound like a bad rod bearing. is it a knock or a rattle
