Lets not get to carried away here. Top end rebuilt with new gaskets?

I think replacing the rear rocker gasket will solve your problem. Oil is leaking down onto the exhaust manifold and smoking. The intake for the blower motor is right their so naturally its going to pull some of that smell into the car. If you can do the work yourself its a cheap fix.
