I've been noticing a really weird sound at idle when I pull in my garage after a long drive. I just had my timing chain replaced last year and all maintenance is up to date. The noise sounds like a rattle or a squeak and goes away as soon as I give it a little gas. The car has 84k miles and hasn't thrown any fault codes. I've taken a video of what I hear. If anyone recognizes what it could be, let me know so I can have it looked in to. Thanks!

 

Maybe you've done this already, but check engine oil levels at least once a month or sooner. Usually chain rattling/slapping sound is due to low oil (from my experience)

 

Already checked oil levels and they're normal. The video I posted was after a 30 minute drive once the car was at full running temp too. I know the timing chain noises usually go away once the car warms up.

 

Bump. If anyone has any ideas of things to at least look into, that'd be good. I could go to the mechanic and say "I want whatever's causing this sound fixed," but I don't want to rack up hundreds of dollars worth of diagnostic fees and them not even find anything.

At 80,000 miles, what kinds of things should I be worried about?

 

I have an 08 mcs and had same problem had to replace timing chain went to dealer for service yesterday and found out open recsll on timing chain and tensioner( misspelled)
call dealer and ask might get it done for free I got reimbursed

 

I just had my timing chain replaced last year. Did yours idle like this even after it warmed up or only on cold starts?
