    How loud is the ticking?? The engines in the Tacomas are not very well sound dampened. They are noisy. They are known for the ticking, and many things can cause it. A couple examples are the Injectors, and the "Lifters". The Engines use a Shim under Bucket valve adjusment, and they are noisy.

    What oil you running? Is it worse at start up or pretty much stays the same? If the lifters are singing on the highway, then you should be able to hear a pretty good tap at idle.

    Sounds like the lifters. Please share the screwdriver theory.

    I had a similar issue with my 05 Tacoma V6. I can hear a ticking/clicking noise that becomes more pronounced under acceleration. I found out that there was a TSB for the 05-06 model's exhaust manifolds. Supposedly some were prone to leaks. I took the truck to the dealership to have them check it out but they said the noise is simply the injectors. I know we have different trucks but another thing you might want to check would be for an exhaust leak caused by a manifold crack. I am no mechanic but thought I would pass the idea along.

    Its up to you. My truck makes a lot of noise but when I took it to the dealer to have it looked at, I was told it was normal injector noise. If you are seriously concerned, I would take it to get looked at. In my personal opinion its better to look like an idiot in front of a mechanic than to look like an idiot in front of thousands of drivers as you sit stranded on the highway.

    If it seriously concerning you then take it in. I tend to be cautious, especially when it comes to my truck!

    The subject bologna is not directed at you CaptainFun.
    It troubles me that Toyota can call this "normal"!!
    Injectors can make a ticking sound but I think the tick heard in gen 2 Tacoma's it something more. I have a 2011 Tacoma and it the tick really kicks in around 2k rpm and I can even hear it at hwy speeds. It's more pronounced under light acceleration (with a load on the engine).

    Not all Tacoma's do this. The three 2010 v6 I test drove had no tick.
    Mine sounds like an exhaust leak but I'm fairly sure it's valve train noise.
    Why do most claim it's on the left (driver) side?
    I suspect it's a quality control aka poor assembly techniques.
    -OR- may be related to the variable valve timing mechanics?

    Toyota doesnt build alot of sound dampening into their engines, as other manufactures do. Being an aluminum engine, its going to transmit noise quite well. Have your truck looked at. Some ticking sounds have been related to an exhaust leak. Otherwise, it could be the VSV, injectors, valve train, etc. In some trucks, the ticking isnt as pronounced, but they all do it.

    A main bearing is more like a knock than a ticking sound....and it's very expensive.
