Subject: engine rattle
IP: Logged

Message:
I have a 94 dakota with a 3.9 V-6. When the engine idles, there is a rattle coming from the front of the engine. It sounds like a taping similar to the sound of a bad lifter, but the noise is diffently coming from the front of the engine. I've been told it's the timing chain and that it's a common problem with the V-6, and that Dodge has a timing chain tensioner that will take care of the problem. Has anyone installed this tensioner and was it difficult to install? Thanks!

Yes,what you've been told is correct.There is a tensioner availableand the installation difficulty is essentially the same as replacing the timing chain,approx. 2-3 hours labour.

Message:
The dealer TSB regarding this issue also calls for replacing the timing chain when installing the new tensioner so plan on that when you decide to do the job. For more info on what is involved check out www.speedtweaks.net for a description. You'll find it under "Tips and Tricks" then just look for the "Magnum V6 Timing chain TSB"
Hope this helps.

yes i have a 2001 3.9 v6 and i was getting a rapping almost knocking sound out of the engine
it almost sounded like it was valve tapping or i threw a rod
the dealership said that it was a timing issue
and since my truck was all computerized they would have to go into the computer to fix the timing
the only kicker is that they say my truck is too "new" and they dont have the soft wear
i said B.S. and started running 93 octane gas in it. the loud knock is gone but i still hear a faint rapp ocassionaly
I FEEL YOUR PAIN MY FRIEND
DOES ANYBODY KNOW OR HAVE ANY SUGGESTIONS TO MY PROBLEM
I SHOULD ONLY RUN 87 ITS A BRAND NEW TRUCK!

If you have a 3.9L V6, HAVE THE TIMING CHAIN TENSIONER INSTALLED!! I ran a copy of the "Magnum V6 - Timing Chain TSB" (found on SpeedTweaks - Tips and Tricks webpage). Gave it to the dealer service rep when I dropped off my '92 V6 Dakota at 80,000 miles. They installed the tensioner as detailed in the TSB and BINGO! This is the first time my truck has not rattled! The truck has rattled since new - I always thought it was lifter/rocker noise. The fix was not under warrenty, so it cost me $390.00, but IMHO, it was WELL WORTH IT! Very quite - at last!
Thanks!

We have a 2001 Chrysler Sebring LX Convertible w/15000 miles on it. It has had a constant tapping/rattle in the engine. It has been to the dealership 3 times with this problem. The first time; they "could not duplicate the problem" although everyone else could certainly hear it and told us about it.The second time it was in they said the problem was was due to the oil; but it did not need an oil change because it had just had one. They suggested that we wait until the next oil change and then use synthetic oil. The noise (tapping) got louder and we took it back. The last time it was in to the dealership they put synthetic oil in it(charged us for an oil change)and said it was a dirty lifter and the synthetic oil would take care of the problem. The problem still exists. After reviewing comments made by others in this website with similar problems, I am now wondering if it could be associated with the timing chain. Chrysler dearlership has taken a ho hum attitude and I am out of patience.Today I spoke with the manager and he suggested that he take a ride in w/me next week. It really isn't necessary to ride in the car as one can easily hear it when it's just idling. There are two other dealerships within 20 miles and I'm considering just taking the car to one of them with the suggestion of the timing chain tensioner. What do you think? Thank you for your input.

the sebring has a timing belt not a chain. The problem is either piston slap or rod knock or lifters collapsed.

As an update to my post of 1/20/03 just wanted to thank slopehead for the input. Turned out that after taking my vehicle to two more dealers there was major sludge in the engine. (second dealer kept my car for ten days and never turned a wrench) The sludge was so thick it looked like an engine that had in excess of 100,000 miles with never an oil change. My car has a little over 15,000 miles with proper maintenance. The third dealer is currently putting in a new engine. Last week they ordered a new oil pump. No one seemed to have a clue as to how the sludge got there. (guess they didn't think of poor manufacturing and poor quality control) So much for "Five Star Dealers."

Yeah, i just replaced the timing chain on my 94, and it takes longer than the 3 hours to do the job, its more along the lines of a 5 hour job. YOu have to practically take the entire front engine off to get to it. Its well worth the time though. as the engine now runs like new. For mine, i think the timing chain was just flat worn out as it has 163000 miles on it. Its also advisable to replace the thermostat while you have the motor apart like that.

I just posted for the same problem, I think. When my '03 Dakota sxt 3.9L V6 is stopped or in park I feel the truck shake. It is not over powering but it just does not feel the way a new engine should run. (It only has 550 miles on it). I also hear a ticking noise. I have been told that, that is just how the engine runs from a local mechanic but I am skeptical. does anyone know what this is? Is it normal?!?

I have the same problem with my 3.9 magnum rattler, I have already purchased the three piece timing chain and want to make sure that this will solve the problem, until reading the notices posted about a tensioner for the chain, I called the dealership, they claim there is no tensioner for the 1996 3.9 magnum V-6 rattler, so I tell him about my research, I was also able to find the part number for this add on part, #53021195AA, I am not going to replace my chain until I get this tensioner for this.
note: you Dodge Dealership Parts Department will know little about this unless you have the parts number #53021195AA
Thanks a Ton

I have the same, truck and same problem. I am going to try and re-route and replace the coil and spark plug wires this weekend, and see if I am maybe just getting crossfiring on the cylinders, but if anyone else knows what's going on, that would be a big help. I have read of a couple of other people having this problem, too, but no answers yet....
