My V8 has a ticking noise that you can hear when the hood is closed... When you open it, it gets quieter, but when you stick your head down there, it's actually the pintles on the fuel injectors that are clicking open and closed very rapidly at idle.

Its just injector noises, the Altima is very loud at this too, nothing to worry about. What you are hearing is the injector opening and closing.

update on ticking

After a few days of driving since the oil change with Lucas and the filter change, the ticking noise is pretty much gone! I am very excited to get this outcome. I have read people's opinions on additives such as Lucas and I've seen mixed reviews. I even read about a test conducted at "Bob knows oil.com" suggesting that Lucas may not be as good for the vehicle as advertised but I have also seen many members of that forum saying how wonderful it is.

I have had my own experience with Lucas on a previous vehicle (97 Tacoma) and I sold the truck (after 9 years of usage) with 162k miles and no problems...

The injector noise has also decreased drastically by using Lucas fuel treatment (UCL). I did use the Chevron fuel additive and it did quiet the injectors down some but I feel like lucas does a better job at a lower cost...

I hear you...I was not aware of it prior to purchasing the 4R but now that I have seen everyone else talking about it, and the fact that lubricants quiet the engine now tremendously, I am very happy with the truck. The fuel additive is a plus all around, I now get a little bit better gas mileage (1-2 Mpg overall) and it feels and sounds smooth and quiet. Now I can dedicate some time and $ to mods!!

Try the Redline SI-1 fuel system cleaner, that stuff works good. It pays for its self in fuel conservation. The plus is that it cleans your fuel system really good. It idles smoother now. As far as the ticking noise i dont have any of that at all, not while i had this car anyways.

After two years and about 32k miles my 06 SE V6 seems to have stopped ticking. I had no luck with the dealer, usual excuses. I had given up on it since it seemed to be harmless. The last few weeks I haven't heard it. I have always used Mobil 1, but no other special treatment. Except for the tick, it has been perfect. Maybe Toyota has developed a self repair technology.
