Hard to believe you bought a Muscle Car w/ a V8 and are THAT concerned about gas mileage..

But its your car, drive it how you want.
Let us know when the chain goes.. (again..)
I'm not here to argue, I'm here to find answers. I didn't JUST buy the car for gas milage, I drive it about 33,000 miles a year and I also didn't want to have to buy Z rated tires, premium gas, or pay the damn government a $1400 gas guzzler tax! They get plenty of my money as it is now!

I would also like to stand up for Chrysler a little bit here too from my experience. I know lots of people here are beating them down but face it guys crap happens! While my car was in the shop they supplied me with a loaner car the whole time, and when I got my car back they also renewed my warrenty for another 3 years and 36,000 miles. I don't think they are really running from this thing, I just think some of us drive a lot faster, a lot more often than maybe what Chryler tested for so the problem may not have been found by them before production. All in all I would say Chrysler treated me pretty good during the whole thing, it was the dealer that did the repair that took forever and should have done things diffrent.

It has still not been proven that MDS is the culprit to the TC failure, so I'm not so sure using autostick full time is the answer. I'm using autostick as much as I can now especially on the highway but just not enjoying having to use it exclusively driving around town. IMO it may help somewhat but I don't think it's the answer to saving the chain.

So that's why you got the R/T? The smaller tires cost less if you got the 18 inchers over the 20 inchers
So anyone that's going to get a Challenger should get an R/T or SRT in with a manual transmission.
If you need to drive an automatic then get the SXT?

Does anybody know for sure??
I believe the tensioner is a self-contained unit (no oil pressure operation).

The oil port is to provide lubrication of the chain/sprockets to keep the sprockets and chain from wearing (and putting metal particles into the engine).

Folks, if you're new to this thread you need to research it for answers..... plenty of pics and specs have been posted for your information in the back pages.

Whoever is stating the tensioner uses oil to supply pressure for tension purposes is a hack, and should have his ASE certs taken from him, if they had them at all. I get really pissed off when no nothing techs try to BS customers to make it seem like they are some kind of wizard mechanic. There are some awesome techs around, they are a scarce lot...........

i'll post a video of how to inspect the VVT solenoid, if there is enough interest. It's not hard at all if you have just basic skills....

Cheeers......

It seems like the autostick in city driving strategy to avoid mds shouldn't be as much of a pain as it sounds (remember, mds isn't just on fulltime just because you are in auto mode...it has to detect certain driving conditions before it comes on). Mds isn't going to come on until your speed goes steady, and you are mostly off the gas pedal. So you can run around town in auto mode for most of the time and not even hit mds. When you hit your cruising speed, slap it over to autostick, and that will keep mds off...that's the only time you have to worry about, really. If you have to slow down and change speed a lot again, go back to auto mode. You'll get the auto gearshifts and no mds, because mds will likely stay off as you are on the gas to run through the gears.

09 Challenger R/T automatic...4 tires, stick-on convex mirror, seats

It's not that I really needed 370 hp...but having 150+ hp riding shotgun at a moment's bidding w/o a 6000 rpm moonshot is what makes me feel like I'm in the right car for me. The roar of a v8 seals the deal!

The Google keyword is "ethanol-free gas". The truth is coming to light. Check out http://pure-gas.org/

Timing chain break at 27k miles

I haven't been on the site regularly in a while, so have missed the conversation around the timing chain failures. My Challenger is a 2010 5.7L R/T w/ auto. Last weekend I was traveling from central Indiana to Des Moines IA for a conference. 20 miles from Des Moines I experienced the same thing others have posted... cruising on the interstate at 70, MDS on, when suddenly loss of power, ETC and CEL warning lights, then engine dies. Towed to the dealership and after tearing it down, they show me the broken timing chain. Both that dealer, and my local dealer swear this is the first time they've heard of anything like that....hmmm. Got a call today, the dealer says Chrysler is approving replacement of short block and heads. They think potentially 2 weeks to fix, will update when I get the car back with comments on availability of parts and the service.

This car is my 4th vehicle with a 5.7 in it. I previously had a 2007 Durango, and 2009 Challenger, and now own the 2010 Challenger and a 2011 Ram. I traded the Durango at 56k miles, and the 2009 Challenger @ 26k miles, and only have 10k on the Ram, so not sure if I just was fortunate enough to get rid of the others before this cropped up, or if it's w/ newer engines that have been using cheaper parts.
