Break in oil really necessary? - 07/25/22 12:25 AM
Fresh slant 6 here ready for 1st fire. '74 motor so solid lifter from factory.
0.020 over, new pistons and rings, reground original cam
Don't see anyone nearby that has Penn, Gibbs, etc specialty break in oil. I do have 2 bottles of COMP break in lube on the shelf.
Been a while since I built a flat tappet engine.
Is the flattering lobe issue a new/used cam issue? This is a reground original cam.
Done by Oregon cams,it's their #819.
I do have new lifters but they're probably 20+ years old. Plan on changing oil right after cam run in.
