1970 C10 Oil flow issue

[Ironangel]

NEVER break a motor in with Lucas Oil Stabilizer! You shouldn't even use a 40w oil on break in. Why? Because not only does the cam and lifters get oil from the splash effect, those rings need that oil to properly seat! How do the rings see oil? "Splash!" Ever seen Karo syrup splash? You may have lucked out on the cam, but that smoke in the crankcase indicates blow by which shouldn't be there on a new rebuilt motor. Your valve covers indicate the same, a dull layer of smoky residue. Wet and clean is what you want to see on the inside of them valve covers. Run it like you stole it, keep that PCV intact. And "never" break a motor in with 40w and Lucas Oil Syrup! "Jus Sayin" For the future rebuild...
