My 2002 F150 with 5.4 with 160,000 miles developed right side lifter noise which came on slowly over a months time. Much reading mostly here gave me a plan to possibly help. I have been using full synthetic 5w/20. I used 10w/30 at the last change and by the time the engine used the first qt. which was around 4000 Miles the lifter tick was gone. I did add a pint of Mystery Oil when the tick started and it did not help. I suppose the thing to do is to keep using the 10/30. I always thought the 5/20 was too thin but used it since the truck was new. This does bring on conversation about whether to use the 5/20 im trucks that have not developed lifter noise. Thanx to those that posted on this issue.
You have a Modular Engine which doesn't have lifters. I suggest you stick to 5/20, you don't know what your talking about or what your doing. Thinking you can outsmart Ford engineering in this case will cost yuh.
BTW, so you get this right, - noisy lash adjusters come from either snake oil, crappy oil filters, incorrect oil viscosity or the engine over heated at some point. Basic, -if you throw the owners manual out and feed it with what ever is on sale in the flyer, they will get noisy. First thing to go is the lash adjusters along with scratchy starts. It begins with cold starts only. Eventually progresses to warm idle as well, if you continue to pimp your engine.Feeding it Marvell Mystery Music adds to the problem quickly, since it's basically used in push rod engines as they have the tolerances for it, very old remedy used to quiet one down enough to sell. Adding saw dust to that stuff helped even more.

Sometimes the truth hurts, hopefully OP takes this info as a hard lesson learned rather than the "F****** everyone here" route. 😆

Hope so, sounds a little harsh but straight up. What screws them up is using inferior filters or just the wrong oil for extended periods. Additives, - what may have helped older engine designs can be poison to the modulars. Tolerances are tighter, lash oil pathways need the right stuff or they go dry. Can't go wrong going by the manual, -or retroactive TSB's from Ford/Oasis correcting their owners manuals recommendation. Hell, because mine was a 98 model, the Ford/Oasis TSB came in the mail, -informing me about the oil recommendation switch for these modulars. Ford did their part imo. they can't do much about poor maintenance and stupidity.
02 - For a split second just before throwing the front wheels back on the other day, the 98 made me think of your truck. Still can't figure that out, -
If you have a 3 inch body lift spark plugs are pretty easy, next time ill take a video
So much for the clueless act, looks like you just revealed yourself Skylar, Jacob or whatnot. That's too bad, 10thGenFnatic would of been a cool ID for somebody.....trashed it.
