Yes, that is what a message board is for and people on here have been very helpful. This problem is frustrating and so far I've tried everything that I've been advised, to no avail. I apologize to anyone I might have offended who has suggested anything to me.
So, "Opinion", keep your smart as replies to yourself please.

Hollis - Contrary to your remarks, I'm afraid the info from "70below" actually is just more conjecture and opinion. Piston slap would be very unusual in a 4.7; as it is built to fairly tight tolerances. We don't see that Chevy problem, nor do we have aluminum blocks.
Daddio often offers quality advice though, as you noticed. Good luck with your problem.

Oh, Ok. I think I'll just try to forget about it. Maybe if I ignore it, it'll just go away. :)

Brandon, I have a '01 4.7 with 180K miles currently. It has had Mobil1 5w-30 its entire life, and still doen't need thicker/"high mileage" oil, because it uses only 1/4 quart every 5K miles. I use NAPA 1085 oil filters, which basically is the size of a 1980's 318 filter, but has identical mating surfaces to a OEM 4.7 filter. Between the synthetic oil, the anti-drain-back flap in the NAPA Gold (also on Mopar), and 89 octane fuel, I have absolutely no starting/ pinging/ ticking issues. The OEM spec for the 4.7 is 5w-30 year round. Tennessee had a record 30 days of 90 degree+ in August. No problem for my Dak.

01 next gen 4.7
I know the sound well. My 4.7 did that for quit some time and I was told and also read on many posts that 4.7's just do that after a while?! I grew up working on old chevys 59/68. That was not a good enough answer for me and I knew that it had to eventualy be leading to some type of repair and could be fixed as the motor did not make that sound before. As time went on, so did some timing parts. For me it turned out to be in the timing realm. It ultimatly lead to: One timing chain, one timing sprocket and a timinig tensioner. Dont frustraite yourself by taking it to a mech and asking them to find the cause of "THE KNOCK" problem.
If they do a tear down of your timing chaine areas they should find the noise maker ie : chain, sprocket,tensioner. I am sure that if you ( as barney fith would say)"NIP IT IN THE BUD" it will cost you alot less to do the repair. Dont be miss lead and let it go on, is my advice! (Take or leave)
I have about 99,500 miles on my 01. I bought a extendend warranty to 100,000 in 2000 when I purchased the truck new. I have been very satisfied with the next gen 4.7 throughout the years.
I would like to put a 4.7 in a 68 camaro.
10/17/07 UPDATE
When my 2001 Dak 4.7 startd making "THE KNOCK" it had about 65K 0n it.It is now at 99K. My extended warranty coverd all parts and labor for the timing Chain, sprocket and tensioner. I also asked the dealer to check my Electric cooling fan while they had my truck. As I suspected, the fan is bad, and the extended warranty is also covering all parts and labor on that.Throughout the year I have used my extended warranty for :Three Ox Sensors (3 seperate times), one Power steering pump,one Front wheel bearing assembly and now this timing Knock issue and Elec Fan. I would be happy to send anyone copies of the papper work for the findings and repair of "THE KNOCK". I run Royal Purple oil in my Trans, motor and Diff,WOW what a difference it made in the DIFF,SO SMOOOOOTH SO QUIET!!!
The Extended Warranty I bought was not by DODGE.
Respectfully:
HENRY in CALIF.

Thanks for the info Henry. I do have a follow up question to your info though. Did your Dakota make this knocking sound all the time, just on cold start ups, or here and there? Mine seems to just do it on cold start ups, but I think it goes away later on. Like I had stated earlier in this post, the dealer kept my truck overnight and started it in the morning and couldn't here the knocking. So, I don't know if it is intermittant or just the dealer not listening close enough. My truck is a QC Night Runner and I am planning on trying to keep it nice, so I am planning to not drive it in the snow and salt this winter. So, it won't be getting a lot of miles on it. I have had it since Feb. and it is just under 7000 miles. I am going to try switching from a Fram to a MOPAR filter and change my oil from 10w-40 to what is recommended, 5w-30. I am not due for an oil change yet, but since I am probably not going to get to the mileage before I park it for the winter, I think I will just do an early change so I can get some driving in and see if the probably goes away or not.
I will let everyone know what I find out. If it doesn't change the knocking, I will probably be back on here asking more questions. Thanks everyone for all your help so far.
Brandon

I certainly don't believe myself to be any sort of expert or to know for fact that you are experiencing "piston slap" just offering my opinion based on previous experience with personal experience with a a problem I know is prevalent in some GM and Ford products, but I certainly don't know that occurs in Chrysler products. I do know, that simply because a vehicle is designed with tight tolerances and a cast iron block does not eliminate it from experiencing a problem in actuality. My belief that this may be what you were experiencing is simply based on your description of the problem and the dealers response. I also know from personal experience however that many dealer operated shops (and auto shops in general) tend to be unable to duplicate/diagnose/or troubleshoot a problem without a computer logged trouble code. My opinions are just that....opinions, and do with them as you wish. I apologize if my opinion was interpreted to be fact.

OK guys, I finally got around to changing the oil in the Dakota last night. I switched from the FRAM filter to the MOPAR one, they sell them at Wal-mart now. I also switched from 10w-40 to 5w-30. I still stuck with Valvoline though. Well, after changing it and starting it up, the knocking was still there. That was last night. Started it up this morning and the knock is pretty much the same, if not exactly the same as before. So, I am now out of ideas. I am thinking I will probably end up taking in back to the dealer again and try and be there when they start it up so I can point out the noise they are not hearing. I just hate for this to be something more serious that could potentially ruin the engine.
If anybody has any more ideas, throw them my way.
Thanks

Brandon, I too have tried everything that has been suggested. Most suggestions I've received have been motor oil related, but apparantly that is not the problem. If you come up with a solution or find out what the problem is, please post it here. Let me know what the dealership says. When they start it up cold, they HAVE to hear it. It is very obvious. I too am worried that this could potentially ruin the engine or greatly reduce the engine's life.

Hollis: I agree that they HAVE to hear it on cold start up. I just don't know how they didn't the time I took it in. When I wrote the last post, that was the morning after I had changed oil. That afternoon when I went to start it, as soon as it idled down from the cold start up, it started knocking like crazy. I think it was worse than before. So, my theory is that the thinner oil did make a difference and the difference is more noticable now. Unfortunately, with gas prices doing what they are again, I am thinking I am going to trade the truck in already. I am looking at getting a SRT-4 Caliber. I really like the truck except that I have to drive about 40 hwy miles everyday for work and the gas is killing me. Plus, like I said, I am worried about that engine knock, so I figure I will let them worry about it.
If I change my mind and decide to keep the truck and then have them look into the knock again, I will let you know what I find out.
Thanks

Will them hearing the knock cause the trade in value to go down, even though it is still under warrenty and they would have to fix it one way or another? If so, I am going to just keep the truck for a while and keep taking it in until they can find the source of the knocking.

i wouldn't put it past some of the dealers we have around here. but good luck whatever you do. i'd still put a mechanical gage on it to see if it is an oil pressure issue on that cold start up

Yup, you never know what a dealer might do. I had a new Chevy once with a clunk in the transfer case that the dealer who sold it said was normal; while another GM dealer wouldn't accept it in trade because of the noise.
