hmm weird poping metal noise when engine is off
 

ok after driving and engine is fully warm.. then i cool down and turn it off like usual... i don't know if i just noticed it but when it's off, the engine will have once in a while "clicks" or "metal pop" sounds...

i don't know if i heard this before in N/A mode.... i remember for sure after you turn off the engine, there are some sounds like metal ticking or something??? what is it?? oil dripping??? or something? exahust???

do you know what i'm taking about?? those tick tick tick or something like that metal sounds when you shut off engine.

metal expands when hot and it shrinks back to shape thats most likley what your hearingafter you turn off

Alot of cars do this, sounds normal.

yeah my crx does that too but never really figured out what it was....??

pretty sure its the exhaust system metal. my car only does that in the winter time here, but when it does its pretty loud... sounds like "tack tack tack". its a normal thing... dont even trip about it unless you got other problems. you live somewhere cool/cold?

Never had it with my cars (no A/C).....
My mother's cars did and both had A/C
I think it might have to do with having an A/C ???

no its just exhaust parts :)

Re:hmm weird poping metal noise when engine is off
 

oh ok...I think my exhaust parts are so old that they don't expand and shrink anymore ::)

exhaust eh?? hopefully... sound's like from the valve cover.... all these years just wondering....

most likely the heatshields that surround the exhaust.
