Usually the ticking is valvetrain.. The 660's are known to be a little loud because of valvetrain.. The cam chain could also be wore. I took my motor down to do rings and my tensioner was on the last notch and had a shiny spot were it can't adjust anymore..

Yes is has a self adjuster. It only goes so far though.. You say your quad is 04? I can almost bet your chain has never been replaced.. Your tensioner is probably maxed out like mine..

Timing chain will stretch beyond the auto tensioner's ability to tighten the chain... once this happens you need a new chain.

When the chain has worn to this point, it whips around in the case making some quite nasty noises that sound like valve tap on steroids. Your's sounds pretty much the same as mine did when this had happened.

Simple timing chain replacement (with a reset of the tensioner) fixes it.

You can test by doing the following (in this EXACT order!)

1) remove center bolt from timing chain tensioner
2) remove spring from center
3) remove tensioner mounting bolts
4) remove tensioner
5) check tensioner ratcheting rod - are there only a couple of notches left on the rod? If so, chain needs replacement

6) reset tensioner rod - pull pawl away from rod and fully compress rod into tensioner
7) replace tensioner in case - tighten down mounting bolts
8 ) place spring into center
9) replace and tighten center bolt


When re-installing tensioner (if during chain replacement, wait to do 7 and beyond until head cover is fully installed and torqued down) you must follow 6-9 in order or you WILL damage the chain, cam and cam journals.

i did just what you said and its 14 clicks out. i did not pull adjuster clicks all way out cause i didnt know if it wouldnt go back in..

now im going to adjust valves, but if a rocker is loose do i tighten them down like i would a 350 engine...what is the process for this.ive looked on google but fount nothig on this..the proces to tighten rocker arms not valve adjustment

thanks guys

If you removed the tensioner with out removing the bolt and spring first it will be all the way out.

Yes! 99% likelihood that this is the cause of your noise. Mine, too, was at 2 clicks and making noise - replacement chain fixed it.

This post is 9 years old. You may not get a response from the OP. Look next to the post number and you can see when the post was started. For old ones, you are better off starting a new one.
