That's how it was done on the early engines. It works. Greenpeace might start picketing your house though.
I'm not too wild about vacuum retard and exhaust gas recirculation in the early, crude pollution control systems (modern versions are amazing) but the burning of crankcase fumes is a one of the good ones. Engines actually run better with a little bit of a draw from the crankcase. It's worth the trouble to do it right.
I would use the 90° fitting but go up. Fit some mesh in the line and plumb it into one, or more, of the air filters.
Since my last report, I drove another 11 hours and my oil consumption is still zero. That's better than having a litre or two pumped out.
