Hello everybody, I'm new to this forum and already see alot of info here. I did a quick diesel forum search and found this one. I bought my first diesel in august and I'm happy with it,( except for fuel costs ). It's an 07 Ram 2500 with the 5.9L, stock and it's now got 4k miles. Anyway I've got some loud knocking, clanking sounds coming from the head area. I noticed this is something that is gradually getting louder the past mo.. I was talking to my uncle as we were warming our trucks up last night and we both could tell there was something wrong with mine. He's got a 05 5.9L and his was quiet. Any insight on this would be great, Thanks and Merry Christmas!

 

Welcome to DTR,

I would say that if your 07 is louder than your uncles 05 then without listeneng to it I would say take it back to the dealer and see what they say.

Just my .02 worth

 

On my way to Dodge of Bellvue this morning. I'll post any info I get.

 

Tie it to an old broken-down Ford and drag it at 70MPH up and down hills for approx. 2 hours.
Nah...Really... My '06 did the same thing until I got my wife out of it. The cure for mine was to work it harder. She puttered around in it all week and by Friday, it would be rattling pretty bad. Even when I drive it unloaded, I let it get to about 3rd gear and hammer it! Getting the engine fully warmed up and loading the engine good has REALLY quitened mine down.

 

Ditto on the towing. These engines need to be put under a load as part of the break-in process; the sooner the better. If this is not done you are likely to have an engine that consumes oil after about 30K miles. These engines were originally designed for industrial uses, without consumer use in mind. W.hen a trucking company buys a brand new truck, they aren't going to baby it for 3K+ miles to break it in; it's going into service immediately.'

P.S

The sooner a Cummins is put under a load, the sooner it's fuel economy will improve

 

Check the blue clamps on the fuel lines near the head. They may need to be tightened. Someone here has confirmed this is a problem that causes a loud ticking/knocking sound.
I also agree with the required work out for the engine. After I tow with mine I notice it is much quieter and smoother.

 

Now this is what I'm talkin about, a forum with members that know what there talkin about! Thanks for the suggestions. No more lettin the wife drive it, I'm going to drive it like I stole it. ( not really ) I'll make it work.
Thanks again!
