Yes I have used the search button but cant find any info, bought a used 2011 hhr with 2.2l that had rattle at start up. Done some reading on forum about timing chain tensioner replacement, so I replaced tensioner but still had rattle. Next step I took was replacing timing chain and balance chain with all new accessories, no rattle for about a month. The bad news is the rattle has returned but I cant find out why. Any input would be great.


Thanks

Welcome to the site, you mention accessories, do you mean chain guides and sprockets?
Just to confirm did you use the new style tensioner and did it engage itself or did you need to activate it?

himwestr

Yes new guides, sprockets and new style tensioner activated. Both kit where cloye brand.

Hi,

Maybe one of the guides either broke or is loose.. It can happen even with new parts...

Does not rattle all the time just once in a while at start up. Thinking about pulling valve cover off this weekend and taking a look. Might even try a another new tensioner.

My suggestion as you suggest, open it up and take a visual!

Have you checked out TSB PIP4716A ??

Cam Phasers not parking properly. Pulley alignment and/or Serpentine belt replacement.

Replaced s-belt when changing timing chain, alignment looks fine. How do you check cam phasers?
