I have an 06 f150 with the 4.6 it has 255k miles. About 230k miles it started a ticking that seems to be coming from the passenger side valve cover area. The ticking will speed up and slow down with idle but seems to get faint at higher rpm in idle. While driving under acceleration it will turn into a chattering but smooths out after letting off the gas to cruise. I did a full tune up (plugs and coils) it went away for a couple days then came back. Ticking started again only after the motor getting to normal temp. Now it’s just constant. Anyone have any idea what this could be? I’ve been reading a lot of forums and listening to audio clips but I can’t seem to find an exact area to look or sound alike. I have a video but can’t figure out a way to upload
