HELP! '99 rodeo 3.2 engine knocking
 

ive always been an isuzu pup/luv diesel man but recently i bought a clean one owner rodeo because i was confident the noise in the top end would be the timimg tensioner. turns out whatevr went wrong in the bottom end caused a noise in the top too. i overpaid, thinking is was the timing so now im needing an engine without costing a fortune. does anyone reccomend somewhere to buy one? is there an isuzu graveyard somewhere? thanks in advance.
