Ticking and bogging down
Anyone have any ideas on what might be the cause? I have a 2006 4.6l f150, while heading north through the mountains the motor started ticking bad, and is bogging down bad. Takes a bit to get up to speed with constant tick. Loud when started for about 30 seconds, then just the tick is heard. Thought maybe a sticky valve, put valve medic in, no improvement. No cel or other lights, oil and temp gauge are steady. Checked all fluids, oil smells like it may have gas in it. Any ideas?

Exhaust leak? Possibly a cracked manifold? I know a lot of times a cracked manifold will quiet down after it warms up. Maybe a broken stud on the manifold?

The cam will need replacing probably due to scoring on the lobe. And then installing new followers, as well as lash adjusters while they're in there, etc. Should be fine after that.
