Need a little advice!

Hey everyone!

I am pretty new to the forums, but have found the information extremely useful so far! I just reciently purchased a 2010 F-150 XLT 5.4 Supercab 4x4.

I'm not much of a gearhead, but I was hoping someone might be able to shed some light on some questions concerning some noises I've been hearing coming from the truck!

First I dont know if its the injectors, or supposed to sound this way, but the engine ticks... its fairly noticeable outside the cab, and occurs right from startup on a cold engine and continues into normal operating temps. I've asked the dealership about it and they say its normal, even started a few f-150's on the lot, they make the same tick. Does this sound like a normal engine noise? It doesn't sound like a diesel or anything, just a constant "tickticktick" even when bringing the RPM's up.

On to the next noise.... If I pull up to a curb to put some resistance on the engine, or press the brakes and lightly push the gas, you can hear what almost sounds like a rattling or clacking sound, different from the constant engine noise I was describing above. This sound only occurs when the truck has some resistance on it, and its at a low RPM, below 1000 I think. push the gas just a bit further, or let it return to idle, and the noise dissapears. Could this be a loose heat shield or something?

Like I said, I'm not very mechanically inclined! haha! But I'm hoping some of you out there might know, or have heard what I'm talking about! I love my truck, but I'd hate to think she was starting to fall apart at only 2000km! I'm hoping its just minor though!

Any help would be greatly appreciated!

the ticking could be from the octane in the fuel not sure how it does it but it compensates for it causeing a ticking i had it on my old 2000 i had had it in several times at 3 dealers because i thought it was BS but all 3 had the same diagnostic and a few other trucks i herd also had it.... if you run premium its a waste so i was told (unless tuned of course)

Hey thanks for the info! I run regular 87 octane fuel, but maybe I'll try a different gas station or something to see if that helps. The first sound I described may be normal according to the dealership. I even went to the dealership and got them to start up a couple trucks and they all sounded much like the first noise I described. And I've taken a look on the net a videos of people with bad cam phasers and whatnot, and I dont think thats it, atleast I hope not! haha! The sound mine makes isn't very loud, and it doesn't sound like a diesel either. I'm a little more concerned about the rattling sound when the engine is under a light load. ha ha, maybe I should just turn up the radio.
