Ticking occurs when in Neutral and quits when accelerator is depressed. Also occurs in Drive when truck is stopped with foot on break. When in drive and foot on break, noise also stops when acclerator is depressed. has only gotten slightly louder after first hearing it 6 months ago. occurs with hot or cold engine.

Any thoughts on this would be helpful. I will be getting a stethoscope and pin point where its coming from.

thanks

Might be the insides of your catalytic converter have deteriorated. Under low exhaust pressure it rattles or ticks. Higher pressure prevents the rattle or perhaps masks it. Give it a shake when its cold.
