As stated in the title, my friends car sounds like it has marbles... What could be causing this?...

TIA

 

huh? a rattling noise?

 

Yeah it's sounds like it has marbles in the engine, could it be running lean?...

 

detonation will sound like rocks or marbles if it's bad.....

Rod knock as well, but it always sounds like marbles.

What motor? Could be on it's way out.

 

Well my friend took the car to the shop and it came out worse... She said it sound like it has marbles I haven't looked at it I'm just trying to get some opinions on what it could be before I actually look at it.

TIA

 

It sounds like detonation to me - I'd tell her to stop driving it before its time to replace the engine.

Why did she initially put her car into the shop?

Well it's a friend of a friend so I'm not really sure... Let me find out and i'll post more info.

 

Is she using cheap gas, could be spark knock.

 

its prolly that dinky single cam he has under the hood

 

does the marble sound get louder the higher the rpm's are?

Yup.

 

it's time to replace your rod bearings

 

I had a dizzy go bad that sounded like it had marbles spinning around in it.

 

i've got marbles in my **** too...only hear it at about 1/3 throttle in all gears. It's a cross between the sound of my car digesting marbles and almost a sputtering sound. I want to say I feel a slight loss of power too.

from what i can tell it's either...

ignition timing
belt timing off by a tooth or so
dizzy cap/rotor bad
valve lash needs adjusting

I'm leaning towards the timing because I feel a slight loss of power as well, and for some reason I just don't think it's the dizzy. I replaced my plugs/wires last week, so I know it's not that. I'll be posting results as soon as I do anything.

 

A rattling sound at a certain rpm/throttle could definitely be the rod bearings. When mine went I only had the rattle part throttle (more if there was a load like an uphill). For the longest time I thought it was my exhaust rattling.

 

well that sounds scarily close to my situation. hmm, anyone link to a good head removal post?

 

mine sounds like that only till it gets warmed up, any sugestion about this, same subject..

 

try a heavier oil, 20-50 or even a 40 or 50w..

You are a moron. Do you have any idead how many different things this could be?

Leave.

 

No one's mentioned the possibility of bad Lost Motion Assemblies. Mine have been making the same noise you guys are describing for quite while now. Mine is a certain rpm rather than dependant on throttle. did a valve adj., checked timing, tried pulling the spark plugs to test for rod knock, and its still here. waiting on new lma's, but I'm almost certain that's what it is.

Thats pre-detonation at its best, i would just run better gas!

 

coudl just be valves ticking and need to adjust the valves...if its rod bearings, from a cold start...it will knock loudly

 

A bad cat can sound like it's got marbles in it as well. Can you locate where the sound is coming from?

 

he says its from the engine
