Doug,
If you can tell a noise is coming from the bell housing area while you are driving down the road with the pedal to the floor you must have INCREDIBLE hearing. Sorry, couldn't help it. Spark knock is only heard while you are driving and you press down the gas pedal and cause an instant load on the engine. The "knocking" sound is the result of the air/fuel mixture exploding/detonating at the wrong time(not just the right second) and the explosion is causing the piston to rattle inside the cylinder.
Sorry, I am sure mine ticks also but assuming it has it has done it since new so thus I am not concerned.

You must have great hearing. I purposely drove my wifes truck today to listen for ticking and could not here anything like you described. I am going to try it again in a few minutes. I have to admitt I like the sound of her truck so much that I sometimes just start it up and listen to it run for a couple of minutes!!! I also drive it with the radio off at least once a week just listening for things that do not belong. Has the dealer told you what exactly the sound is???

There are a couple of "known" ticking sounds that the 4.7L daks may have.
The first one is the Evap pump that pressurizes the fuel tank to test for leaks. It is mounted on a double-rubber hanger under the hood on the firewall just above the engine on the Drivers side. (above the left cylinder bank) It makes a tik-tik sound for several minutes while the Evap tests are performed. Ususally right after starting engine.
The second "ticking sound" was the subject of a recall on the 2000 Daks. The 'fix' was to re-cable the ground wires under the hood. I guess that some later Daks may experience the same symptoms if the body-grounds are not well connected. (paint under them?)

(sandman)I am just stating some facts.
Do not forget that for several years after the 4.7L was first put into Dakotas, folks complained about their 45RFE auto trannys not shifting when engine was cold. In ALL of these cases, it turned out to be the engine-fan was roaring for a couple miles (not the tranny at all).... My point is that this "ticking sound" may not necessarrly be from the bellhousing.

There is somthing about the reference to the OIL PUMP that bothered me... Thus I just referred to the 4.7L semi-hemi factory documentation.
The oil pump is on the FRONT of the engine and nowhere near the belhousing. Obviously the dealer tech that told you it was the oil-pump gears was mistaken. (Also, the 4.7L uses a gerotor-type oil pump that is somwhat unique)

Bruce P, I follow you now. I mis-understood your point! Ya, I doubt it is comeing from the bell houseing! I did everything but get the stethascope out. I am almost inclined to agree that the sound must be reflecting from some place else. Doug does it only do it when hot or cold?????

I also experience the same ticking problem with my truck. I got a 2000 model 4.7L with 48k miles. I can not hear the ticking sound when it is in idle; however, I can definitely hear it when driving. I can hear a slight ticking when reving the engine in neutral. I asked around and they all said it has something to do with my cam or lifter. I was told that my drive cam might have to be adjusted since it is a SOHC engine. Am I correct to assume that it can not be my lifter since it recently passed state inspection? Any input is greatly appreciated.

Christian,
Are you joking, right?
the 'drive cam'? SOHC ingine-4.7, 2 heads,= 2cams
why not start a new thread, this ones pretty old.
Oh, and I don't know what state you're it, but here in Texas, your lifters have nothing to do with a state inspection!

It might also be an injector. In some cases, a fuel injector can tick. And TT, it is a SOHC engine. Each head has one cam operateing the intake and exhaust valves. A DOHC has 2 cams on each head, one for the intakes, one for the exhaust. Just me .02

Todd,
Thanks for your response to my question. If I sound like I don't know what I am talking about, then you are correct. I am not a machanic by any mean. I was told that if my lifter is bad, then the engine runs too rich or something like that and that I wouldn't meet state inspection.

John,
Your response was very insightful. You are right, it could be the injector. I can hear my injector if I stick my head under the hood but can't hear it while in the cab. However, I don't know if that is causing the annoying ticking sound while driving, because I can hear the injector on my other car and it doesn't tick like my truck when I drive it.

JOhn Milner,
could you please READ my post?
Here, I'll cut and paste what I said again:
SOHC ingine-4.7, 2 heads,= 2cams (meant to type engine, not ingine)
It says 2 heads=2cams
Look JOhnny boy,
I did my HO cams myself, I've been rebuilding engines as a hobby since I was 12y/o-minbikes then.
I know what the h@ll SOHC means, and I know that my 4.7 V8, any V8 for that matter, has TWO heads, and since it is a single cam per head, and they're 2 heads, oh wait, let me get out my calculator here. OK 2heads=2, times 1 cam per head=1, so 2x1=2
Wow, I was right when I said:
SOHC ingine-4.7, 2 heads,= 2cams
JOhn, what engine and mods do you have again?

To follow up with your injector suggestion John, I just talked to the Dodge dealership, and they said it could be the fuel silinoid. Not sure what that is but sounds like I need to take my truck in for service.

Sorry TT, misread your post, but you're response was obviously nothing more than from someone who obviously needs some anger management classes. Perhaps you've been dealing with kids to long.....
welcome to the adult world. I was only trying to offer some info for the original post,....isn't that why we're here? Guess I'll find another Dakota site, with less children and more mature responses. Outta this POS site!!!

I have a 2002 club cab 4.7 (yep the guy looking to get a 4wd quad cab but the brakes sound wierd so I am holding off for now) 2wd and when it was new, I would hear a slight tapping (dull sounding)coming from the engine (back by the bell housing) area and kind of ignored it for a month or two until I was a gas station and while idle, I could hear it real well, especially when you clicked the A/C on (put a load on the motor). The truck would make this sound cold or warm. I brought it in the 5* and they called and said they could not find anything. I told them to shut the windows and turn the A/C on and when they do, to listen for it. Well, they called me and said they found it. Loose torque converter bolt which was knocking into something.. They tightened all the bolts and it has been quit since... I also think faster since maybe the controller was picking the noise up as a knock and slowing things down a bit.
Truck has been great for me since (last February) but now looking for more room since the club is not cutting it when I haul my family around town.

to get rid of that ticking noise you have to look under your truck at the driveshaft. If you see a zip-tie around it.. that's what is causing that ticking :) zip-tie may be exchanged for a piece of nylon rope with an attached piece of metal or brick, but ods are, you would know if that were the case.
sorry had to laugh
