5.4L motor noise
I have an '05 F150 with the 3 valve 5.4. Seems to have a top end ticking noise than gets slightly louder after the engine is brought to operating temp.
Doesn't really seem like valvetrain to me (higher pitched than a normal lifter), is it possibly an injector?
Just wondering if anyone has ran into this problem before....
p.s. It is a fairly high mileage motor for the year, almost 87,000
