The hole in the SB timing retainer bolts is normally in the hole that is exposed to the puddle in the cam side of the lifter valley allowing oil to seep through it and drip down onto the steel directional tab onto the chain   Cheap and fast for some additional oiling to the SB timing chain, ask Larry Shepard who designed that part originally and which college that engineers degree was from  The oil singer is designed to sling oil off of it and stop oil from being splashed up into the seal area of the timing chain cover, especially when braking hard No magic here  Thanks for making my point. Neither the slinger, the drip tab or the magic bolt does anything of consequence to oil the timing set. You can use them, or not and you'll never ever know it. Or, you can put pressurized oil on the timing set. Nah, why do that? Because we go to great lengths to eliminate internal oil leaks and keep oil on the crank, at least in a performance/race engine. Not drill holes that spray more oil around inside the engine.
If the results don't match the theory, change the theory.

I use a slinger on ever big and small block Mopar I build. Nothing else and I’ve never had an issue.

Not drill holes that spray more oil around inside the engine. I'm all for controlling oil in an engine, but I'm also sure you need oil on the timing set. If you are THAT worried about oil in the timing chain cover, run a belt drive.

I use a slinger on ever big and small block Mopar I build. Nothing else and I’ve never had an issue. And I agree. You can run them as they wont hurt anything unless you install them backwards, which I've seen enough to know some guys who refuse to degree a cam should also not assemble engines. If you can't degree a cam or install the slinger correctly pay someone to do it. In reality, the slinger does very little. It damn sure won't stop a timing seal leak because I've fixed many of those that had slingers. To me, they are just a little piece of metal that serves no purpose.

I personally would rather drip oil that is of no consequence to loosing any amount of oil pressure. Once the oil leaves the galley, it is no longer pressurized oil, it is directed oil. Sort of like the purpose of the bolt/ tab.
We all have preferences. Thinking through the ENTIRE scenario will lead most people to the same or similar solutions.
Is drilling the retainer not splash oiling? How much pressure can you lose with a .060 hole and that's a damn big hole. I think my last one was .039ish and that's plenty. There is a difference in the oil coming out of a pressurize gallery and what drips out of a bolt hole from gravity. I have a timing cover I cut open that I use when I run a gear drive and a mechanical fuel pump (another reason to put some oil up there I forgot about...oiling the fuel pump lever and eccentric) and I can also put oil to the system and see what that hole produces for oil to the timing set. It isn't a drip or a fog or a mist. It comes out at whatever pressure/RPM you are testing at, and it gets the oil on the timing set.

The slinger was another way to try and bandaid an oiling issue. That slinger has zero to do with stopping oil leaks past the crank seal. The seal doesn't function that way.
Tell us more. What more do you want to know? The slinger won't fix a seal, and it doesn't affect timing chain life. It's useless. My query was regarding your statement "The seal doesn't function that way." If you limit the volume of oil that contacts the seal lip(s) doesn't that help the seal do its job? In an industry that pinches pennies to save thousands I question the "useless" label. If it was useless it wouldn't be there.
