Noise is when truck is started and goes away after about 15/ 30 seconds of running. Sounds like a desiel or like the exhaust has a leak at the exhaust manifold .

    without actually hearing it we can only guess.But common issues are with the timing chain tensioners and guides.Also make sure the oil level is full and oil change interval has not been neglected.
