as far as that much oil being sucked into the cylinder from the intake it would have to be a sizeable hole in the intake, which should give you a bad vac. leak, which you should be able to see or hear, or the motor should show low vac. reading. also if you had a hole in your intake with a vac. leak, then it wouldn't be blowing oil out of the breather, it would have a suckion at the breathers as if you had a pcv valve on it.
if you dont have a pcv valve hooked up you are gonna get some blow by out of the breather, so i think you have a small vac. leak at the intake, or valve guides, thats causing the tail pipe smoke and the breather smoke is normal.
