Ok guys, believe it or not, the 572 is finally coming together and I have a question about AC Delco E.O.S. oil additive or Crane cams oil additive for break in. I know these additives are recommended for flat tappet cams, but what about roller cams? Is it necessary? Will it hurt anything?
I also read that E.O.S. and Crane cams additive also help prevent cylinder wall scuffing and help break in the lifters. Would it help? Would it hurt?
As the saying goes--I'd rather have it and not need it than need it and not have it.
I plan on breaking in the engine on some old stock, Rotella 15-40, not the new stuff, so it will have higher zinc and phosphorus leves to begin with. Then after break in, switch over to Mobil 1 synthetic.
