Apparently my 351 has a failing lifter and some blowbye. I know what I should do but would Seafoam, Marvel Mystery Oil, or Restore do any real good? Money is tight so replacing lifters, etc. is too much $$$$ right now.
blowby is probably rings, and the lifter is probably oil pressure, use some stp with 20w 50 for now, a rebuild is in your future, and there is no magic fix
