developed a tick today...

the truck that is:mad:

i thought i have noticed a small exhaust leak before, and while driving today, all of the sudden it got louder...it is very noticeable while driving, quieter while idling, but still noticeable, even with the loudest squeaking belt i have ever heard.:confused:

got out and let the truck idle, even stuck my head underneath and i cant really tell where it is coming from. i know it is on the drivers side though.

i didnt smell anything burning or see any smoke anywhere.

any suggestions on how to make sure it is just an exhaust leak?

would there be any signs of it being engine related? burning smell, smoke, etc..?
