How many of you have what sounds like valve train noise with your 5.4L? Zach and I had a discussion on this a couple months ago, and he said his 5.4L did the same thing. A friend of ours from church works at the Ford dealer, and he said mine sounded exactly like his 2010 F-150 with the 5.4L. Mine is quite when it cold, but you can hear the "ticking" noise when it gets hot. Other than the noise, it runs very smooth.

check out this video, it should help you figure out what noise youre hearing.

than scroll down and click on the "5.4 VCT Theory & Operation" video. its boring but pretty informative and should explain the noises youre hearing.

Great link Patrick!!

From the sound examples, my noises are normal.

There is also a section on the procedure for changing spark plugs on the 5.4L!

I didn't watch the video, but mine has done it since I bought it too. Pretty typical of the 5.4L as I understand.

Trent

Yeah I thought the noise was typical so I didn't think anything about it.

It is. Mine did it and was pretty consistent. Never really bothered me though. btw after owning a diesel i probably wouldnt even notice it.

Mine does the same thing. I had the dealer look at it while my transmission was being replaced, and they said that it was normal sounding to them. The noise doesn't seem to get any worse or better with temperature or changes in oil viscosity, so I don't believe its mechanical wear.

Cam Phazers....and if it starts to get louder, change them.

Hmm, interesting. Never really noticed. I'll have to check now.

Mine's always made those noises.... among other ones!
