02' F-250 w/5.4 Rattling Noise
#1
![Question](https://www.f150online.com/forums/images/icons/icon5.gif)
I have a 02' f-250 with the 5.4 V-8 and 31K miles. The other morning when I started her up, I noticed that while in Park, I revved her up to 1800 RPM and noticed a "Rapping or Rattling" sound coming from the engine compartment. I don't hear it when she's in Drive and moving along. Anyone else encounter this or hear what the problem could be ? I'm scheduled to bring her in for the 30 K check-up but I would just like to possibly have som good intel before I go to the dealership.
Thanks, PM

Thanks for the reply and sorry I took so long to respond. I brought it in to the dealer and they showed me a technical bulletin that states that the noises are due to "Light load operating conditions and the normal bore clearances present in a cold engine". States that this noise has no affect on performance or long term durability. Oh, and speaking of performance, I recently tried a fuel additive by Lucas Oil. I noticed an increase in acceleration performance and 1-2 MPG improvement. A friend turned me onto it and he swears by it. Only about $7.00/ bottle and it treats 100 gallons of gas/ diesel fuel !
