Did you ever get this figured out?

 

no I did however drive it 1000 miles with in two days and I drove perfectly....

im maintaining oil changes about every 2 months, and will continue that for the duration of its life I suppose. (Rotella)

 

I had my engine rebuilt about a year ago on my 03. The shop advised me to use the Valvoline VR1. After the break in period I have been using it with no problems or ticking sounds. I've changed the oil 3 times since after puting about 10K miles on the new motor.

 

I’ll try it!!!

 

If you were using 0 weight oil, and switched to Rotella, maybe, maybe it would cure a slight tick.
But what you have is a good running engine with worn out bearings...that tick.
Sorry, but changing your oil is only wasting money.
Drop the oil pan and pull a rod and main cap and you'll see for yourself. You can swap them all then too.
Maybe the cam bearings aren't noisy yet, and crank and rod bearings alone fix it...and that wouldn't be a first.
It's under $75 and a few hours under the truck.

 

I disagree...04's are more known for slipped liners than any other year.

That sounds more mechanical like a lifter etc.

Take a hose and hold it to your ear, move the other end around your truck and try to pinpoint the sound.

Take a cup of trans fluid and add it to your crankcase oil. "Sometimes" it helps fix a lifter.
Change your oil after running it a few minutes.

Other than disassembly...idk how else you'll fix that.

 

I disagree back, lol.
I've heard this a few times now, on a few trucks, including my own 04.
I replaced lifters, pushrods, a cracked oil pump, exhaust gaskets, and a new timing chain, then pinned liners...and that identical sound persisted.
The rod, main, and cam bearings were all bad.
Not the first time I've read of that being the problem and new bearings being the fix either.
One way to find out, and it's not hard to do......

 

I had the same sound on my 04 I bought a couple months ago, although not as loud. 83k miles. I changed the oil to Rotella 15w-40 as well as put in a 180 thermostat with a coolant flush. Now I only hear the noise maybe once every two weeks and not for very long, also being much much quieter and less violent sounding. My .02

 

maybe change your water pump and it will go away completely. I’ve heard it could be the pump.


also during my 1000 mile road trip I noticed the sound was not present when I hit gas stations (after hours of driving)

 

Lets not throw around made up statistics. If you've polled the forums and have data counting all the reported years with slipped liners, thats fine, but this whole culture of made up info is very misleading.
