Hey guys, anyone can tell me whether I possibly need to replace my 1989 2.8 v6 engine if it just needs a timing belt? It's knocking and right now I have been looking into buying another used engine but if there is another possibility please let me know, thanks.

 

Unfortunately it is impossible to diagnose an engine by the simple description "it's knocking", though that is usually a (very) bad indication.

Is there a particular area the sound is coming from? Do you have any video/sound clips?
