I have a 5.4 in my superduty, and it was replaced with a 2001 5.4 motor after noticing a diesel sound when starting up in cooler weather. I find it has the same noise as before, but also notice it sounds like it has a valve ticking noise in the upper rpm's when driving just before it shifts. It drives fine, and has lots of power, just wondering if this is typical to this engine, or if I have problems that are gradually getting worse. Any info would be appreciated, and if there is any TSB's related to this.
Cheers,
Dale
