Wow! Thats it! I checked the manual, and its located right behind the larger timing gear, I havent taken them off yet, but I can tell through the holes in the gear that that retainer has been replaced. Im guessing sometime in this truck's history it blew a timing gear and the retainer too? and a part fell deep into the oilpan. Would it be possible for the retainer to break causing the gear to break, or would it have broken because the gear broke??
Oh well, I feel better now knowing what that piece is, now I Just gotta figure out how to take the timing gears off and put new ones on...
Thanks alot!
