Ticking sound
Need some suggestions. Have a 2000 F-150 Triton 4.6L V-8 w/ 121,000 miles. I have ticking at lower passenger side area of engine. Also the truck shutters at 70 mph. I think it's the engine because I let off the gas and it's a smooth ride. Only when I hit the gas at that speed does it shake. The front-end is new.
My vacuum test showed steady 20 Hg- no fluctuation, which I understand to be a healthy engine. All sensors test good ( no codes ). Oil is new and at proper level. Fuel filter, IAC valve, and O2 sensors all new. Radiator recently flushed. Please tell me it's something reletively simple. Any thoughts ? Thanks.

My guess would be a broken exhaust manifold stud or two. Good luck!

aren't you afraid of it warping the heads?
as well as robbing fuel mileage and HP?
