I had a 84 350 dump 4.9 with a lower end rap, drove it that way for 5 years never got any better or worst, run it. Ran same way when i sold it.
Once had a 240-6 that developed a lifter tap for quite a few miles, eventually went away after a few oil and filter changes.
Had a '93 300-6, low miles, that sat in the junk yard for six months or so. Put it in another truck and it had a collapsed lifter. So, we put a piece of card board in front of the radiator to let the truck get hot while idling, not too hot. The lifter freed up and the tap went away.
Looks like someone just was into the lifter gallery cover on that truck. Wonder if it has any balls of silicon loose in the engine? Suppose you could isolate the lifter, remove the valve cover and gallery cover, then look at the lifter.
Chances are, it will clear up, unless its a bent push rod. Good luck.

Believe it or not I blew a 300 six up in my
86 F150.. It had a piston slap noise forever
in it. One nite on the way home from work #2
piston tried to switch holes. It was below Zero
& I wasn"t walking.. Had to put the truck in
Low Range to get up one grade... Let up on the
gas at the top of the hill above my house &
She locked up. I coasted it right to my Shed.
If the door would have been opened it would have
made it to the chain Hoist.. It ran 298700 Some
miles befor it blew & the last 100K with a Piston
noise.... I had already bought another trk for
the motor & tranny. Drove it to work a day later.
Still going strong!!! BTW If you run the Smaller
OIL filter on a 300 Six ya don"t EVER hear the
rods rattle after start up..
Yep, that was me. Valve cover too. New gaskets, no silicone.
Inside looked good and clean, nothing out of the ordinary.
Oil looked good and clean, but I didn't know what it was or
how long it had been in there so I changed it today too.
Most of the tick went away just changing the oil.
55 psi or so cold with the new 10W30, drops to about 30 at idle hot.

This is the perfect time for; Ta DA !! ATF. Add 1/2 l to your new oil. I'd wager an entire dollar that you have a smidge of dirt in a lifter and the ATF will root it out. If I'm wrong, I will have to get a mortgage on the 'rancho', but worth a try. HTH

Bob Harvey,
I'll second that ATF treatment, solve many a-lifter tick.

I've got a few engines around here that sound like that. Is it
always there or does it do away when it is good and hot? I
hate to tell you this, but you might not get another 200,000
miles with that tick.

I've used Gunk Motor Flush to clean out a sludged up engine. It's a quart of thin solvents and detergents. Use it in a fully warmed engine and only at an oil change. Add it to the hot dirty oil, let it idle 5 to 10 minutes without reving the engine, shut off the engine, drain out the hot oil and change the filter.
The Motor Flush did nothing to fix the existing cracked piston, no one expected it to, but it did save some labor on cleaning parts. As we disassembled the engine it was surprizingly clean inside.

Doesn't sound all that bad. The good part is the valves are adjustable in those. I bet if you do the ATF trick and run the valves it will quit the tick. I had a 300 that made that same noise. It only went to 300K. Put another engine in it and a coat of paint on the body and kept going. Great old truck.

Hard to tell from the sound track, but those 300's
were notorious for piston slap. Seen them run
forever making the noise. Not much you can do for
it, just the nature of the motor.
Just make sure it has some oil pressure, especially
at low idle, warmed up.

Stop by your auto parts store that sells "Lisle" brand equipment and buy yourself a automotive stethescope, and probe around right to it. Of course, you could roll a piece of paper into a funnel, hearing aid, stick it in your ear like a horn and zoom right to it as well. Sounds like a lifter out of adjustment. Its a 300, do as others say, add a little ATF, see if it doesn't clean it out.
Drag racing great and car builder extraordinaire, especially engines, now deseased Bill Jenkins used to have a helmet that he sometimes wore that had two car horns stuck to the outside, drilled and plumbed into his ears. He used it to tune himself into the sounds of his engines going down the 1/4 mile. No joke. I'd tell you to make yourself one, but after watching your video, it wouldn't be worth it, and your neighbors would whisper and point at you behind your back...so try the ATF trick.
Good luck.

What does the double fan belts drive ???
1 quart ATF costs what, 6 of 7 bucks? A new lifter is 4 bucks. Since you've been in it recently you shouldn't need new gaskets.
BTW, some 300 have adjustable rockers. Some use a positive stop set up where you just crank the nut down until it's tight against the shank of the stud.

It would help if you took the fan belt off and shoot another video... It could also be a exhaust leak, To check cut a 6ft are so 3/8" hose (it could be smaller) hold one end up to your ear and run the other around the exhaust manifold. Check were it bolts to the head and around the lead off pipe... If it were a lifter tick you can find it with out pulling the side cover off...
If I were goona add a additive to free up a stuck lifter it would be Rislon if it does not cure it you are in deep do-do....
A customer dropped by a few days ago with a 92 f-150 300-6 auto one owner garage keep 71K original paint he was looking to buy. It looked new even the underside was clean and rust free... All it needed was a compound and wax job... It was sweet to drive it cruised at 70 with ease... The asking price $3500 I told him to snap it up put new tires and shocks on it and enjoy it... Even the AC worked great... I had forgotten how well those 6's run out..
