Slight engine rattle

I've got a slight rattle coming from the engine compartment but only when the truck is in a higher gear (4th or 5th, usually 5th) and the rpms are low, like around 1000. Anybody had a similar issue?

 

Does it sound like ball bearings rolling in an empty tin can?

 

Yeah, pretty similar to that. Maybe not rolling, more like lightly shaken.

 

are u lugging a manual?

 

Auto trans. I never said I couldn't drive, just have a rattle.

 

OK, probably not the same sound I'm here from my engine then.

 

LMMFAO......................................


then its prolly the rotors in the blower..............around that RPM it will make a clacking racket..................well known.

kinda like the shutdown racket?


I avoid low RPM like that as if it was aids.

 

It's barely noticeable. In fact I doubt I could get good enough audio from inside the cab to make it worth the time to try to record it.

 

It's possible. I had a 2010 that I put 50k on and never noticed it. Guess I need to keep the rpms up.

 

worse uphill at low rpm?

 

Yep, precisely. I only noticed it once today and it was on a long, windy, uphill climb right after a downhill run. So the truck was in 5th as I entered the first curve. Started rattling as soon as I gassed on it again.

 

Yup, on a longish climb even a sublte graded one I down shift just for that reason.

 

Well, I scrolled down a little,and found this. So much for the search function.

U can hear THAT tick at idel........ Usually not the rotor tick from my experience.

Do u hear a tick, or a rattle?

 

The difference in sound is immense

 

Well, that depends. Imo, a tick is something that has a regular and consistent pattern. A rattle has no consistency to it. Forgive this goofy example, but for instance.

Tick:
Ta-ta-ta-ta-ta

Rattle:
Tata ta-ttttttta-ta-tatata-tatatata. Ta. Lol

 

Not sure if I hear it at idle. I'll have to spend a little more time with it. Only had the truck for 5 days.

 

the tick from both n/a as well as f/i sounds like an exhaust leak almost.

the blower is LITERALLY a rattle....................go to ur truck, open hood..................start it, leave door OPEN and lean out and listen to the truck when it shuts down and u will hear the rotor rattle.

better if u can remain outside and have another person shut truck off.


also I believe the "tick" should be driver side dominant

 

What octane gasoline are you running? It sounds like loading and pinging to me. Try a higher octane gasoline for a tank or two.

 

OP has blower, lets HOPE for premium right?
