2011 Ram <300 miles-Bad engine noise

[Shortline]

Just got back from a 2 week trip (not in the truck-Flew), jumped in the truck this morning, fired up my new 2011 Ram 5.7 with 290 miles, and was horrified to hear a LOUD rythmic knocking sound, kindof like a lifter, but coming from the back lower end of the engine from what I could tell. Taking it in to the dealer tomorrow, but thought I'd try here-What in the world could be making that much racket? Sounds like metal smacking metal, but doesn't seem like it's coming from the top end. Never heard anything like it before....any suggestions? Checked oil, it's good.

Well I'm a little late on this, what did the dealer say?

 

[sullivan]

yes, im curious as to how the dealer treated you as well.

i wild guess but maybe a critter may have gotten up in there....my brothers radiator fan in his brand new Dakota demolished a cats skull one day a few years back...

 

[LB3711]

Sounds like a piston/crank problem

I vote this just because it sounds cool. except for the cat. Oh and the radiator fan.

Travis did you ever figure out what this was?

Did you get it looked at?

Sorry I didn't get back to replying, just got busy and forgot about it! Never did take it in to the dealer-the next time I started after posting this, it just quit-not tappered off, not got quieter, just stopped. From where the noise was, a friend and I figured it was probably something in the exhaust? His theory was an exhaust leak, that seated as it got hot. No idea, but it's been fine for the last 600 miles, never happened again. Go figure. Probably should have taken it in, but with it not doing it anymore, and no codes in the computer, I doubt they'd have looked terribly hard anyway.

glad to hear that it went away.

The worst kind of issue when it may or may not be there when you get to the dealer.

i had a similar problem on my 09. it was the two lower exaust studs on the lower side passenger minifold. they broke off and i herd from a friend about this happing to other 4th gens. it was covered under my warrenty

I got the 4.7 in my 2011 and I have a noise too, left bank of engine, to me sounds like an exhaust leak of sorts, but the dealer tells me this is normal.

At idle speed I can here it over my FM Series 40, so as far as I am concerned it isn't normal. Can really hear it when pulling in the garage too.

Yep if they can't duplicate it, you are basically wasting your time.....

I'm so excited to deal with them on my occasionally squeaking seat Friday.

that is why i always take my iphone and FILM with sound what is happening so that the"well it doesnt do that now crap" is negated.

Not sure if you figured it out yet, but my truck had a tick right after I bought it, it was a broken bolt on the exhaust manifold, replaced all bolts/studs, and gasket, problem solved.
