Is the problem with the timing chain tensioner only on the the 06 and 07's the reason i'am asking i got an 05 ss/sc and get a loud rattling or almost like a knocking sound sometime when i come to a stop or when i pull down my driveway and stop at the bottom most of the time it goe's away if i rev it.

 

get it replaced its the tensonier i had to replace mine 3 times

 

ok thanks thats what i thought it was. how hard is this to replace? Do you just unscew the old one and screw the new one in or is there more to it? Thanks

 

I don't understand why this guy had to replace his three times.
1- factory
2- 1st replacement
3- 2nd replacement
4- 3rd replacement

isn't the definition of insanity doing something over and over expecting different results?

what the F? Canada thing?

 

Ok i just purchased the timing chain tensioner from crate engine depot .com. who has changed this and how difficult is it do u have to remove the valve cover or do u just unsrew the old tensioner and screw the new one in, just want to be sure berfore i get into this. thanks.......

 

there is a how-to

 

From what I've read 05-07 all have this problem. The tensioner is very easy to change though, I haven't done mine yet but I will be very soon and you basically take the valve cover off, take the old one out, put the new one in and put the vc back on.

 

when i unscrew the old tensioner do i have to worry bout anything falling down in the motor? I read the how-to but think that was on the old tensioner. i bought the new revised one. Thanks guys.

 

I wish I would have known about this problem sooner. Mine got stuck open. So far its cost me $700 and I'm not even done yet.

 

ok guys got the tensioner how do u set it before putting it in
