2003 Honda Civic drives fine but makes rattling noise Sign In

Year of vehicle: 2003
Make of vehicle: Honda
Model of vehicle: Civic EX
Engine size: 2.0 (?)
Mileage/Kilometers: 110,000+

For over 1 year now, my car has made a rattling noise, which sounds like it comes from underneath the chassis. It is always present, though sometimes it is louder than others (there doesn't seem to be any rhyme or reason to this).

I found some audio clips online (link deleted .... not allowed), and it sounds most like one labeled "hole in muffler." Then again, it also sounds like it could be "lifter adjustment" or "vacuum hose leak."

There are no check engine lights on the dash and the has driven fine for as long as the noise has been present. If nothing else, the noise is loud and embarrassing, and I finally want to get it addressed. I'd like to get an idea of what the problem is before bringing it into the mechanic so I can understand what cost range I'm looking at.

If you have any idea of what the source of this noise is, please let me know!

Thanks :)

A very common noise is heat shields that come apart on exhaust parts anywhere front on back. Some you can find easily just tap on tail pipe and mid exhaust parts with a rubber hammer, engine off even and better and it will rattle at the problem spot.


If found that is it there are assorted ways to fix depending on how broken or rusted.


Other common is the flex pipe close to engine that must flex with engine motion at assorted loads. If really exhaust leaking you do need to tend to it at once,

Thanks for your suggestions, I will (have my fiancé) check the heat shields tomorrow! I tend to think it's probably not exhaust leaking as I probably would have died from CO poisoning a long while ago :)

Thanks again for your thoughts!
