Timing Chain Replacement

Hi all. I have a 97 Dakota and I keep the service up to a T. I know that timing chains don't typically call for replacement, and I have no current problems with my own, I was just wondering if there was a recommended mileage interval for changing the timing chain on a 3.9 V6? I'm currently at 201K.

On the newer engines, I've usually replaced them around 140K. The engines were still running but had a lot of timing chain slap inside and were running cooler than they should. After replacement, the heater puts out a lot more heat, the engine has more power and the fuel mileage actually goes up because the computer finally gets out of "open loop" mode.

if it's making noise, replace it along with tensioner...if it's quiet...leave it alone

I have a 94 with 108K I replaced the chain with a Cloyes "OE Replacement" (this truck is no hot rod) at 100K, it was noisey as He11; well for the last 7-800 I'm starting to hear it again; i usually go double roller on everything I replace the chain on; I am kicking myself for not doing so this time. fortunately this is an easy chain to do, I'll probably do another this spring after I get my check from Uncle sam. This time I'll do like I normally do and go Edelbrock double roller; same chain set as a 318/360.

Did you use the upgraded tensioner that Chrysler used on later engines? It will quiet the chain right down. I think it was used from 1998 on but will go back to the '92 Magnums.

Hi - new on here so not sure if I should start a new thread or follow this one as you guys seem to know about this issue but I'll go here for now;
Does the timing chain being worn cause running issues as well as the rattle? My truck had a slight rattle when I bought it four years ago and they fixed it before I took the truck (I'm pretty sure it was something to do with the manifold) and all was well. Last year it started a rattle again and I thought it might be the previous problem coming back but having looked into the timing chain symptoms it could well be that as it sounds like it is coming from the front of the engine this time. The running issues that have also started to appear at the same time are that it splutters when pulling away from standing or accelerating from a slow speed - almost as if it is running out of gas. Usually lifting off the gas and reapplying it a couple of times clears it - if you just keep your foot down it will splutter more and sometimes backfire until you pump the pedal to get it to clear. I've changed the front O2 sensor and the Throttle Position Sensor already - the O2 due to the code coming up and the TPS on advice for the spluttering. Both made a slight improvement but neither fixed it so I'm thinking timing chain now if that also causes running problems. Of course it could be something totally unrelated but thought I'd check with you first in case it's not just a coincidence they started around the same time. The truck is a fairly high miler at 320,000 miles (not KM - I'm in Canada but the truck came from Maine in the US) but runs great and has a really nice frame under it and the body is good for the age so I want to keep it going as long as I can. Thanks guys.

With that many miles I'd replace the timing chains and tensioners which certainly have some elongation due to wear, this I'd do if an engine overhaul is not imminent.
Another way is to wait it out if you feel that the engine will need a complete overhaul in the near future, and change them with the overhaul.

I know I am resurrecting an old thread but is it ok to use the upgraded tensioner with a double roller timing chain set like this one?

Amazon Amazon

I am at 140K and starting to hear some noise coming from the timing cover.

Don't use the tensioner if you are putting on a good double roller. In fact, most engine builders say not to use the tensioners. FWIW, only the 3.9L ever came from the factory with a tensioner. The V8s never had them.

tensioner will not work with the double roller....only the stock chain.

I put the tensioner back on my 3.9....figure it will last far longer than i will
