Just wanted to let the folks know that although their Max may have a lot of miles on it, the chain rattle can still be fixed relatively painlessly.
I replaced my tension again @ 400,000km (approx 220k miles), after the rattle got pretty bad. It was so bad, I could feel the vibration through the throttle.
Anyway, i bought the new tensioner kit whiich comes with the tensioner and a new chain guide. The guide & tensioner are meant to be replaced together, because the new tensioner points downwards a little more than the original. However, the guide cannot be replaced using the access hole on the timing cover since there is not enough room. I replaced only the tensioner, the piston does not butt up flush with the existing spot on the original guide, but it works nonetheless.
Basically, I removed the access cover which is located closest to the firewall, as you stand next to the passenger-side fender. You'll see the 2 10mm bolts holding the tensioner in place. Stuff a rag under it to prevent the piston dropping into the bottom of the timing chain cover. Remove the top bolt first, then slowly remove the bottom one. You'll see piston pushing out the piston as the tensioner swils upwards. Carefullt remove the tensioner & piston. The new tensioner has a big thumb tack keeping the piston in, so it's easy to installl. I installed it by putting on the top bolt first and the swivelling it to get the bottom bolt in. This part could be a little tough, it was for me the first time i did it, but the second time was much easier. It also helps to have small hands (size does matter..hehe).
Replace access cover and run car for at least 30 seconds at 3k rpms to bleed off the air in the tensioner. She'll make a racket, but the manual says that's normal. I found that the rattle stopped completely when I took her for a spin around the block.

I had done a similar write up when I first did this...but it's been awhile, not sure if it's still on the .org.

BTW, most mechanics will tell you that it's a stretched chain, as you can see, this is not the case. Parts cost me about $60 Can, which is like $2 USD (haha...I jest ), much cheaper than a complete timing chain replacement. Use the money to splurge on some Altezzas, GTR stickers, any additive spouted by info-mercials, and big shiny heavy chrome wheels, you car will be so fast look really bling-bling


Oh..and after I completed this, then I remembered that I had that sony digicam sitting in the box upstairs...so no pics!
