guidance on additive start up rattle

Liqui-Moly MOS2. DID quiet an old ford escort I have 360,000 + miles on it. plus it worked on on an old,old riding lawnmower that was making a ticking sound from start to finish. I dont know what caused the noise,, old age,, but it DID help.
Just a quick update, after my last change at ~ 60k, I eventually settled on Pennzoil Platinum 5w30 with solid/consistent results, roughly 3 seconds of start-up rattle at every crank and all quiet while running, but along the way my curiosity got the best of me ...
Tried Rotella Gas Truck 5w30 with Lubegard no change in start-up rattle, but, had loud chain slapping noise at idle. It didn't subside/get quieter after 100 miles. Drained, put in Pennzoil Platinum all quiet. Next Oil change tried Rotella Gas Truck again because it was on sale for $12 without Lubgard, no change in start-up rattle and again, slapping noise at idle. Drained, put in PP, all quiet again. Before my recent Oil change had to add 1qt @ 4k miles and then by 7k was at the add mark. Coincidently popped a P0017 timing out of spec. code
. This time tried Pennzoil Gold Syn-Blend (now redesigned?) and very surprisingly got the loud slapping sound at idle. Afte 20 miles drained, put in PP, all quiet. I've pushed my luck long enough, so at 107k miles I ordered a Cloyes Timing Chain kit, GM Actuator sprocket and just found out my neighbor's son is a GM mechanic to help me YAY !

Just an update for those interested, as the start up rattle progressed to a continuous chain slapping, I was able to prolong the repair by keeping it overfilled by ½ qt. for about a year until funds were available. At 118k miles it was loud enough to the point of engine damage. So I replaced the timing chain, tensioner, crankshaft sprocket, VVT exhaust sprocket, intake sprocket and oring on pickup tube and the oil pump inlet oring. There was no damage to the guides, cover, or any of the timing components, just slight wear marks. Comparing chains had minimal stretch. Filled with PP/Fram XG3506 filter and unfortunately it did not solve the problem . I didn't change the oil pump or the rear timing chains/tensioner, two possibilities i may try to address when the weather cools off. So another year and at 131k, its still running strong with no P0017 code. I finally found a donor 2.9L with only 75k miles from a 2007. A tree fell on it and once I got it running, it also has the rattle ... Ughhh
