Re: new ticking sound coming from engine
Try removing accessory drive belt and start the truck and see if noise goes away, if it does start rotating all accessories and pulleys by hand. feel for any rough spots, loose pulleys and of course for the noise. Many engine noises are simply just A rough idler or tensioner pulley bearing on it's way south.

Yep, that's how mine sounded just before the belt busted due to a bad tensioner pulley.
Thought I was gonna have to replace the A/C pulley too, but got lucky with just the tensioner.
I'd check 'em right away, since a busting belt could jack your shiit up if it happens when the hood is open, and engine is running!

I would check and see if the rear exhaust manifold bolt is broken on the drivers side. We have had a few trucks come in with the same thing... |

That was my first thought. Small exhaust leaks go away when the engine warms. |

Re: new ticking sound coming from engine
I'd check the oil, the light did come on, right? Low oil can cause a ticking.

Do it yourself. I did mine and it took less than an hour. If you do take it to the dealership, they shouldn't be charging more than 2 hours labor. (roughly 160-180 bucks?) plus parts (you'll need exhaust gasket, donut gasket and replace ALL the bolts)
