Engine Knock on startup- Scary

In my honest humble opinion, I wouldnt do the kero trick and drive the truck. He said the vehicle lasted another 11 years. In other words, It was an older vehicle that was built with looser tolerances. Motor technology has changed ALOT in the past decade. Some of the old-timer tricks still work. Many dont. No way would i run my truck down the road with the wrong lube in the crankcase!
Like I said before, I wouldnt dump snake oil into the engine through the vacuum booster hose. The problems you are having are not from the engine being dirty.

The only thing I heard in that video was tappet noise. With 200K plus on the engine that's not surprising. I'd buy a set of valve cover gaskets, refer to a repair manual and adjust your tappet clearance.

I could hear it right off the initial start, but I still could not tell if it was piston slap or rod knock. You could try finding videos on Youtube searching for "piston slap" and "rod knock" to see what the difference is...
As far as your headlights go... I know I have covered this exact problem before, but can't remember what causes it off the top of my head. Is it just the low beams that are affected?

Here's a thread I found searching for "driver+headlight+power":
Driver Side Headlight Problems!!! Please Help.
Please put your vehicle information in your signature in your 'User CP' / 'edit signature' and check the option to always attach your signature to your posts next time you post so we know what it is you are driving! Or, create a garage for your truck with all of the details inside (this will show up under your username in all of your posts).

Admittedly, it is near impossible to diagnose an engine noise via the Internet, but I really don't think what you are hearing is coming from the bottom end of the engine. Bearing noise has an inherent 'heavy' or 'hard' knocking sound. The noise in your video is a lighter 'metallic' tapping sound which is indicative of excessive clearance in the valve train. It's definitely not piston slap. Piston slap would not disappear seconds after starting the engine - or at least in 30+ years of diagnosing and rebuilding engines I have never heard piston slap disappear within seconds of initial startup. There would need to be a significant change in temperature before the noise would disappear. IMO you have excessive clearance in the valve train, or possibly a tappet that is dirty/sticking or bleeding down. Instead of spending your money on oil changes I'd buy some valve cover gaskets and adjust your tappets as I previously suggested - but that's just my opinion. Better yet, why not take it to a local reputable shop and let them listen to it? Don't tell them what you think it might be - rod noise, piston slap, tappet noise, etc - just tell them you have a 'funny' noise and wonder what it may be. That way you can get their unbiased professional opinion. Good luck, you could be chasing your tail on this one for quite some time...

and also if it is tappets what kind of damage can it do to the engine over the long run?
