Not a believer in additives - but in my Audi mechanic suggested adding some Magic Mystery Oil and sure enough it quieted down. Go figure.
Marval mystery oil is just trans fluid AFAIK..
You can do the same as I suggested with a quart of trans fluid.
After you do it and see how dark the oil comes out you'll know it worked to desludge the motor and clean those lifter ports...
Just my opinion though and what I use and believe.
I wouldn't do the kerosene one though ..
I belive motor flushes are the same thing... Just tranny fluid in a bottle with a motor flush label...
Marvel mystery oil is NOT ATF. the Msds lists naptha as the primary ingredient (80%) along with mineral spirts (15%) and other hydrocarbons.
quite a way from ATF.
But marvel mystery oil, seafoam etc. are similar, mostly naptha which is a good solvent.
Now I'd guess most motor flushes as you say are similar to marvel mystery oil, naptha and mineral spirts, but not ATF
