Should I replace the timing chain in my 2006 RSX?
I recently bought (private party) a 2006 Acura RSX type S manual with 141k on it. It runs and drives well, except there is a rattle while driving which sounds like it's probably the timing chain. I figure it's probably the tensioner that needs to be replaced but should I get the timing chain replaced as well? I'm sure it's the original chain on it.
Thanks in advance
Being an interference engine, you will be safer changing the timing chain if you confirmed that the noise is from the chain.
Just changing the tensioner is a bad idea. Replace the entire assembly including the tensioner(s), chain(s), sprockets and guides. This is a fairly big job and you don't want to have to do it twice because something else let go.
If it indeed the timing chain, try this first -
