New owner here having a ticking issue I narrowed it down.
I just purchased my 2006 F250 5.4 gas and absolutely love it. Everything works great no issues. My only concern is this ticking noise.
I searched the forum but it doesn't sound like the infamous cam issue or injector ticking. I even search YouTube videos and doesn't sound like those either. The noise is not coming from the front cam area.
Today just looking through the bay while the vehicle is running touched cylinder 5 coil then touched cylinder 6 and found the Ticking!!!!!!!!
Cylinder 6 coil is ticking. I haven't checked it since I just got home could a lose sparkplug or coil make the ticking noise. If the coil was bad it would misfire and I would get a CEL but I don't. And she drives great.
Do not start the engine again before removing the sparkplugs and inspecting the plug hole threads and replacing the plugs with anti-seize and proper torque. You may save some broken coils by catching this early. Read about tune-up on your model to see if you want to do the work. The HT sparkplugs are problematic on your model and it sounds like some are already broken and leaking compression. Someone may have tried removal already.
After removing the coil the spark plug was hand tight! I literally put my 9/16 with a extension and as I spin the socket to slip over I actually felt it spin and I didnt even use the ratchet. So I cleaned the plug good inspect the end all was good put abti seize on the end and threads.
Fired her up and absolutely no ticking or weird noises.
Funny thing is I had asked a local ford dealer about the issue and he quickly searching here m phaser. Its going to be $160 for us to look into it then what ever the issue is charge you for that and parts.
I told him
Sir I build my own motors I just need your advice not a chance for me to break my bank. after searching here for 5 mins a narrowed it down. Dont get me wrong the common cam phaser noises and a loose spark plug sound almost identical.
