A whining or buzzing type noise may develop from the timing chain area caused by excess slack in the secondary timing chains. Nissan has issued a service bulletin (NTB09-128) regarding this issue. Replacement of both secondary timing chains and their tensioner shoes will be necessary to repair this concern. As part of this repair, the engine oil and filter should also be replaced.Google+

Nissan Frontier Noise From the Front of the Engine
Nissan Frontier Problem
Engines Affected: 2.4L 4 Cylinder, 2.5L 4 Cylinder, 4.0L V6, V6
Average Mileage: 81,986 mi (3,000 mi - 225,000 mi)
I first started noticing this whining/whirling noise at about 60,000 miles. It seems to have got worse over time. I recently visited a local Nissan dealer and they told me there was a service bulletin put out stating the problem is probably caused by a secondary timing chain/s. The dealer quoted me a cost of over a thousand dollars! From what I understand they are not over willing to help out those in need, we'll see. I'm going to try and get them to fix it, if not I will take other action. I'll be a horses ***, if I'm going to pay for another bad design flaw on Nissan's part, NO WAY NO HOW. It's time they started taking responsibility for their lack of quality in todays vehicles. I'm so disappointed in Nissan, almost to the point of disgusted. I don't think I will ever buy another Nissan product ever. What ever happened to this company!

I have this sound come from the front of the engine where the timing chain is located. It sounds like some marbles or broke pieces rattling around. THe truck only has 80,000 miles on it and has giving me no trouble but the sound is mainly at start up.
