I would do some short interval oil changes. If you get too aggressive, you take the chance of running a bunch of crud through the bearings when it breaks loose.

Ok. Tech terms not well known here. But the problem is. The I think lifters. Metal straws that deliver oil to top of crank case. My straws are sludged. Most is gone. After using the much needed synthetic oil. Still not clean. I did utube research. Found high miles version of seafoam oil additive. So I take out oil put some in run it for 150 miles. Then change oil. This they say cleans the lifter sludge. Besides popping the top of the engine. Doing this as a break down manual job. Is this an effective route? I also have the can to spray into the engine. I would think that kind of cleaning would be needed after the fact. Is their any other options to make this clean and right again? Or am I on the least invassive path to a clean engine.
Besides those lifter sounds. It runs great at 121k miles.
Side note. Very strong and well built truck. If there is more I can do. Or a better chemical I could use. Please? Want to get more than 4 years out of my truck. Any ideas other than this that include chemicals only. Don't want to open the engine. Thank you.

Watch the advise you get. You say you have oil sludge and people are talking about air intake.
How do you know you have a sludged up engine?

I am a fan of Rislone, it cleans really well without thinning the oil like seafoam.
The big threat doing a fast clean is that the sludge will get into the oil pan and sit in the bottom of the oil pan - right where your oil pump pickup is sitting.
Next thing you know, you smoke an engine due to no oil getting to the pump.
Do it slow, use a high quality dino oil plus 1 qt. Rislone, change the oil every 2000 miles. You will know that you have it mostly sludge free by the sound AND your oil will be significantly cleaner at the 2000 mile oil change than it will be at the first one.
Some people feel that the engine came with oil and that is all it ever needs.
I know I'm a little late to the party here, but one of the virtues of synthetic oil is that molecules are more uniform in size.
As has been advised before, do a few short-cycle oil changes and use a quality filter like Wix, over time, your ticking issue will go away. Once you are happy with it, switch to a quality synthetic, a quality filter (take your pick, I happen to like Amsoil and Wix), and switch to a regular oil change schedule and your truck should last for several more years before giving up its ghost to the machine gods

I wouldn't do extended oil change intervals on a 4.7 any way. Depends on how you drive though to a large degree. All highway or city. Short or long trips. Miles per year. etc
