I recently picked up a very low mileage (4300) '05 Dakota with the 3.7L engine. I've noticed that it makes a clatter when it's first started that's similar to the sounds a diesel truck will make when it starts. It only goes for maybe 5-10 seconds, and then it goes away.
Is this lifter noise, or what? None of my previous vehicles have made this sound before.

mine has done it since new. see my signature below for what I have. Yep, defeinetly sounds like a diesel. Also sounds like a lifter tap coming from the passenger side of the motor. I am just getting ready to bring it in for a fourth time about the noise. It starts within 5 secs of startup and lasts for about 1 to 1.5 mins. My 02 Dakota with 4.7L (non-HO) never made this noise. I also went to a few different dealers in my area to listen to some 06 4.7L HO's sitting on their lot, no noise at startup or anytime.

Bought my '05 3.7 new in late Jan. '05. Never had that start up clatter or any other problem with this truck at all.

nope, no way it's a normal noise. I didn't buy a diesel.

Please let us know what the dealership says about the dieseling sound. My HO does it too, when "cold". Really does sound cummins-like! No other symtoms of malfunction though, ie. smoke etc. Would like to know if it's dealer-fixable.

Yes I also have that noise and the dealer kept it over night to star it in the morning but of course didn't here anything. OF COURSE. I am perusing this until it right. I noticed it more after they did an oil change using Castrol 5W20 even though the manual & oil calls for 5W30. I just can't win.

I'm glad to hear (well, sort of ) that other people are having this issue. Makes my dealings a little bit easier since I know I am not alone. It will probably be a few weeks but I will post the findings once they happen.
If anyone wants to compare the noise, send me a PM or e-mail and I can send you the .wav files I made of the truck making the noise and not making the noise.

Fuel has nothing to do with the clatter want a be diesel noise that happens mostly after sitting over night. The dealer tried, yes I said tried to say it may be normal. I said lets go start up a few Dak tomorrow morning here on the lot to what’s normal. They said that wasn't necessary. They have a factory guy coming in and will keep the truck over night. Yes, I will be there that morning for the startup. Yes, I will have a loaner. Yes if they need to get into the engine, they will own it. Yes, they will order another if that’s the case. I 'm not fooling around. I'm busy and I have life outside of a truck. I want my 32k worth now or it’s gone. I VERY happy for you people that have good Daks but I hope you will respect what some of us are going through.

UPDATE: I left the truck at the dealer last night, they had a regional manager of some sort come listen to it. They all heard it and also acknowledged it is not a normal sound. They want one other regional service rep something or other to listen to it, then decide the course or action. I am down the road of something happening, I'll fill in more as I find out more.
