The V8 models can experience exhaust manifold failures. A leaking exhaust manifold will sound like an exhaust leak or an audible ticking noise from the engine compartment and will be especially pronounced when the engine is still cold.Google+

just started ticking. sounds like it is coming apart when it is cold. goes away when it warms up. Toyota should have a recall on them if they any kind of company and wants to keep their customers

The air injection pump when bad on my 2007 Tundra with the 5.7 V8 at around 40,000 miles in January 2012. When I got my truck back, I noticed there was a noise similar to an exhaust leak coming from the engine compartment. I took it back the next week and the mechanics said they could hear it but did not know what it was. They said there was nothing they could do about it. Two weeks later I was still not satisified and took it back. The service manager rode with my wife and said he could not hear anything and the noise was normal. December 1, 2012 I took my truck in to a different dealer for the recall on the driver side power window control unit and had them check out the noise. Well, it turns out there is a crack in the driver side manifold next to where the air injection pump tubing ties-in. I am 3 months past the 5 yr., 60,000 mile warranty but only have 56,000 miles on my truck. The dealership told me to take it back to the original dealership to have them request an out of warranty repair from Toyota. We will see what happens. I wonder if this is covered by the emissions warranty?

we bought truck new in 2000. it started ticking around 28000. we told dealership and they stated all of the trucks do it. then our warranty ran out and truck has 160,000 miles on it ticking loudly down the road. worse when cold, worse when towing, but does it always.
