Engine Serial Number Decode and Crankcase Ventilation

I can find 1000s of pictures of motors, and have seen actual running motors in cars at all the cruise nights & car shows I attend that have no PCV, and no road draft tubes. How is this possible? Are they all idiots? Did you ever see all the GM cars with just one breather in the intake manifold which just goes into the lifter valley? Oh yeah, Hemis too! Even a Keith Black hemi with those great looking breathers on the valve covers! No PCV there. Are you telling me all these motors are headed toward self-destruction?









I suppose
Ray Barton doesn't know what hes doing either?

And neither does Roush?
