Engine flush... Yes or No???

Brian Bearor said
Just purchased a 63 Valiant and was thinking of doing an engine OIL flush.

Would you recommend performing or not and why?

If yes, what brand would you recommend?

Thank you

I can verify the trans fluid with the oil change works and over a the course of
few oil changes the engine will be clean as a whistle without hurting anything
this method was told to me by an old timer many years ago now I am and
old timer (ha ha)
