Hey guys, I just bought a 2000 Dodge Dakota Sport 3.9L 5 Speed. Love the truck! Since I have bought it, it has developed a ticking/knocking in the engine. It comes and goes. I am hoping you guys know something. I found a vid on youtube that sounds just like it. My knock/tick however doesn't seem to be quite as loud. However it does seem to be slowly getting louder. Mine is worst at 2k-2.5k RPM under a light load. If I give it more peddle, it doesn't knock. But if I am just easing through the gears like grandma it is very distinct at those RPMs. It will sometimes do it at an idle, sometimes it doesn't. Any thoughts??

Here is the youtube vid I found.

Thanks in advance guys!

 

I will move this to the 2nd Generation Dakota Sub-Forum.

 

could be your evap purge solinoid mounted to the firewall mine ticks and inside the cab sounds like a rod knock

 

PCV valve spring shot so the ball is clacking back and forth is my guess these are cheap.

 

Engine light came on yesterday. 3 turns and it is spitting out codes:

P0300
p0303
p0305

Haven't looked up the codes yet. Will do so in just a few. Any more ideas with this new info? Also I will change out the PCV valve today and see if that helps. Shouldn't be a hard job I wouldn't imagine LOL

 

P0300 Random/Multiple Cylinder Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0305 Cylinder 5 Misfire Detected

 

those are easy, p0300 is random misfire, p0303 is cylinder 3 misfire, and p0305 is cylinder 5 misfire... sounds like something a little more serious is going on...

 

Is the evap purge thingy expensive/difficult to replace?

 

to me that sounds like a motor knock. Its kinda hard to tell from the video... I did listen to it from my blackberry... Pull the plugs and check them for water...

 

thats not your noise...
