"Ticking"

[Big "O"]

Last night started a "Ticking" sound, did just change oil, anybody have similar experience?

Don't worry about it. A lot of 6.4l trucks do it. It will go away as your oil gets dirtier. It has something to do with the oil viscosity of new oil as opposed to old oil. Ford did a lot of engine work on some of the early trucks trying to stop this from happening. Eventually, they figured out that the oil pressure hammers certain parts of the block, and you can hear it from the outside of the engine. Apparently other diesel engines also do it, but they are so noisy that you can't hear it over the engine noise. The new 6.4l is quiet enough that you can hear such things. (according to Ford)

Now that you mention it I remember reading a TSB from Ford describing it but man, that will FREAK you out! At first I was like oh god theres no oil pressure, why? was crawling underneath, checked the level who knows how many times. The possibilities of the harmonics in the engine making that exact sound! There are better odds winning the lottery! Thanks for comforting me in my "moment"

Just had my 1st oil change and sure enough a loud ticking noise. Before i read this post i took it to the dealer and they can hear it but have np idea what it is. More techs should read these forums

I have an 08 6.4 Pwrstoke that started ticking. Without having done any heavy towing or unusual driving, the ticking resluted in bad news... a bent rod. Ford replaced the short block. Now the truck isn't the same. During the replacement, they bent the radiators and scarred a bunch of painted surfaces. A real mess.

is the tickin fixed? and do u only have cosmetic damage?

[Isakson]

trust me, engine problems are the worst, cosmetic is better than engine!

[hydrogo]

No, it's in the shop again. Dropped it off this morning for a turbo issue (3rd time).
The cosmetic problems are just symptoms of pride in workmanship.

It seems like they all tick to some degree, unfortunately. I was just in my buddy's Duramax, and it was making a ticking sound. Much like the sound of a broken rocker arm. It sounded almost exactly like the tick my 6.4 makes.
