Oil Canning sound

2001 Siverado, 40000 miles has an oil canning sound or tin sounding pop.
It sounds like it is comming from the exhaust.
I can hear it when stoped at a light and also several minutes after the engine is off.
Any one experience this?

Glad I'm not the only one!!!

I found out mine was comming from the gas tank!!

I got so aggrevated by it, I ended up parking the truck and laying under it with my hand on the tank. Sure enough, a few minutes later. bonk bink I talked to my buddy who's a service manager at a local dealer. He just shrugged his shoulders and said "yeah, some of them do that". Told me to get a life and not worry about it.

Still pisses me off though!!

Whalerboy,
Thanks for the reply!
It is the gas tank.

It's your muffler. You can remove it like I did mine :) Know more pinging.

I have also heard that many times before and when I asked what it was, I was told by a few people that it is simply the tank expanding and whatnot due to it cooling down and heating up. I didn't really like that answer because it sure did sound like there was a little more to that noise but it helped me not worry about it all that much.

my 98 did that I thought it was the muffler
