 Subject: 3.9L motor problem
IP: Logged
Message:
Alright,
I have a 97 3.9L, 3.89, 5-speed, Standard Cab, k&n intake, flowmaster exhuast, RT Rims, a cervins Twin hood, and 3 grand in a stereo to boot. -Needless to say I love my truck.
But I have a "click" in the engine @ about 2000-5000RPM, with no idea what it is.
Brought it to the dealer and told me he thought it was the timing chain slapping around (i guess this is supposed to be common with the 3.9), but it doesn't sound like it's coming fom the case, but more from the head. I've kept driving it anyways, (probably not the smartest move)and the sound isn't getting any worse, but has gotten beyond anoying.
So....
some help here if you please.
thanks

This is a shot in the dark, but the injectors already make a clicking sound, right? Well mine seemed to get louder a couple years ago and it turned out to be my thermostat; there was coolant in my oil. Many a gasket was replaced by the dealership under warranty when that happened. But mine clicked louder all the time.

Nonono - the injectors are supposed to make a quiet ticking sound, or so I'm told, so don't worry about them.
Good luck.

It's not the injectors, I looked and listened, it's more of a metal on metal sound, but has run fine for 5ooo km's now. (with this sound)
The truck had been stolen was stolen, and the insurance company told me they wouldn't invest any more money into the truck unless it wasn't running properlly, (i already had 12000 work on it Canadian) so I have been hoping it would go, thinking it might have been a valve rapping off of the top of the piston , or maybe bent, or even a broken spring. But like I said, the condition hasn't changed, hasn't lost any performance or gas mileage, - I don't know what it could be- other than anoying.
Any other thoughts????

It could be the timing chain. On 98 and newer Dakota they have a self-tensioner on the timing chain (older magnum's do not). If you have to replace the chain go with a double roller chain or buy the stock chain w/ the tensioner setup.

Marc, did you notice any performance difference when you installed your double-roller, or is this a longevity issue only?

I have a 94 3.9 ,have had the noisey lifer problem fixed under warranty at 78,000, now at 150,000 noisy lifter is back. Mechanic told me, as he handed me the old set of roller lifters, that one had collapsed, left front. I called dealer, has been 18 months, or double the km's, was told too bad, so sad...put up with it..The short is, I figure there is a problem with this first run of the New Look Ram, and this re-occuring problem is being buried by Dodge as Your Problem Now..once warranty runs out..sad owner

keith,
I got to looking into it myself,
and haven't taken the valve cover off, but have located the noise with a scope on the passenger side, second cylinder back. Any idea what the price is on a new one, or an aftermarket performance set?
Did your dealer give you any idea as to what caused this??
thanks for the info,
adam

i have a '95 slt club cab. i am having the same problem. i have heard the same noise since i bought it. i had the chain replace at 20,000 and about 10,000 later i hear it again. so i just left it. but now it really is sounding like it may be really flapping around in there. i have 125,000 now and i am about to replace mine tommorrow. the dealer mechanic is a freind of the family and he says that the dakota 3.9 takes only 4.5 qrts of oil and that everyone puts in too much. this makes the crank shaft labor which in turn pulls harder on the timing gear so the chain stretches.
but i also heard from a guy with the same truck as mine, they replaced his and that they re-engineered the tensioner assembly to last longer.
dont know who to believe, but i'll see how hard it is to replace timing gear this weekend

What oil are you guys running? If your comfy with it, move to the next thicker range oil, if it's a lifter that should be a quick...er... well, I hesitate to say fix but the noise should go away :0)

My 94 3.9 has been having that same clatering sound that seems like it comes from the heads. It only seems to do it at idle or very low rpms. It has been going on for a long time now probably 10-20k miles. I have asked around and had no luck figuring out what it is.
If it is timing chain slap how hard is it to fix?
Thanks

Test drove a 96 V6 3.9L Sport with 71K miles today. I also heard this slight metal 'ticking noise' near the fan belts. I asked the dealer/mechanic about the noise.......he said it was an inherent problem with the "timing chain". I think he said it was the timing chain 'slapping". He said it was very common with these engines.
Would this be covered under the warranty(108k mile), or would I have to pay out of my own pocket, if I buy the truck????

Ok Guys.......
It appears most people here think it is the 'timing chain". If I buy this truck will I be covered by the Dodge warranty( 108k mile)??? The truck is being sold by a "second party"....I believe it was bought from a Dodge dealer.
I like the truck, but I don't want to get stuck with a bad engine......
Good website.......found it yesterday in search of this "engine noise'.
Any input would be helpful...........

There are two main causes of valve train located ticking sounds...
1. Timing chain and gear sets
2. Lifters. You can change the lifters out in an afternoon with a compressor and lifter tool. Don't forget new valve cover gasket. Change em alll at the same time. Inspect valve seats and all that while you are in there.
The Timing chain business is a little more involved. Search previous posts on Timing chain for mor info

I have a 2002 Dakota ext cab 3.9 automatic and under 25000 km I have had a ticking noise since 4000 km and took it in and they replaced the lifter, the ticking went away. then 16000 km ticking was back, new lifters again. 21000 km ticking came back scheduled to go in to find the actual problem, hoping for a new engine this time!

I have a 93 dakota 3.9L with the same noises, speedtweaks.net said that this noise that sounds like it is coming from the valves is really the timing chain. I checked and the timing kit is around $50 from auto zone. Plan on doing it this week. I looked at the procedure in the Haynes manual and it doesn't look to be too difficult but from what Turbo Dog says, seems like it might be a little harder than I am anticipating. Any input???

Outcold151,
My timingchain problem was done by the seller/mechanic. If you are not a mechanic, I wouldn't try it unless you have a lot of experience or have 'back-up" help.
If you have to pull the damper, you need a "puller" and the right bolts. You will also need a "torque wrench" when you re-install the cover.
I'm presently re-installing a "damper" on my other truck.......crankshaft problems.......its a 'pain in the butt".........but then again, I don't consider myself a mechanic.
best wishes.....
John....

The clicking sound is coming from timing chain hitting the cover. First replace the thrust plate and for all Magnum engines 3.9L, 5.2L and 5.9L the chain and gears needs to be changed. A double roller chain should be used. The single chain cannot handle the stress, but the double roller chain will last a lot longer and can handle the stress. When the engine gets a little older we use a heavier grade of oil to keep the lifters quiet but it puts a load on the crank and cam and on the chain. I worked on my neighbors motor cause it was in and out of the shop so he asked me to take a look at his motor. Dodge kept on changing this and that and nothing helped. The problem never went away until I took a look at the problem. Placeing an old broom stick to the timing chain cover and the other end to me ear cushened with my thumb I could hear the timing chain rattling against the cover. You need to be exreamly careful. I took a look at the 93's engines and they used the double roller chain. Once I changed the upper and lower gears along with the double roller chain, no more problems. No more noise and the truck can move. One happy neighbor. You need to change the thrust plate reduces the chain slack, the upper and lower gears and replace the timing chain with a double roller chain. Aloha form Hawaii

My new 2003 Dakota with just 1,400 miles developed a loud "tick" audible from the passenger compartment at 1,600-2,300 rpm. The dealership mechanic has made a preliminary diagnosis of wrist pin failure (we're talking a serious problem here).
Should have a firm idea in about 3 days when they have it in the shop and will post the answer here.
