chain tensioners

Get ready for a storm of replies on this question. The short answer is to check/replace the secondary tensioners ASAP. The primaries hold up much better and should be OK given your mileage.
Cost will vary from a few hundred bucks if you are handy with a wrench (spanner), to $600-$800 at an indie shop, to $2000 at the dealer.

I just finished doing mine, new adjusters with shorter bolts from Sng Barratt $140, Felpro gasket kit $50, I used the zip tie method, no special tools required, torque wrench, socket set (with wobbly extenders) open end wrenches and a tube of RTF gasket sealer. Job took about 2 hours a side (if you don't count the 6 hours searching for a lost bolt) Mine is a bit older than yours with the same mileage, the old plastic tensioners crumbled when I removed them. I swapped out the old spark plugs while I was in there. $50. Just do it my friend, piece of mind is priceless.

My understanding is the first gen tensioners gave an audible ticking sound, but only sometimes about the time they were to fail. The next/2nd gen tensioners had a spring in them which masked the ticking sound or prevented it, giving no indication of impending failure, so in effect were the worst of the two! In any event both will be past their sell by date now and it is imperative they are changed, regardless of mileage!

The problem only exists on the 4.0L engines.
Some say they were changed from engine s/n 010813xxxx but this is uncertain as I understand.
So you are safe. Happy driving
