The tube that points up beside the filler cap goes or used to go to the air cleaner. It's supposed to pull crankcase gasses into the air filter to be burnt, that's what the little bob weight flapper controls. If you don't have a stock air cleaner maybe try a hose running to the bottom of the car somewhere to get rid of the stinky oily stuff coming out of it.
The tube on the fan shroud is for the evaporative smog system, it should go to one end of the charcoal canister if you have one, the other end went to the air cleaner. If you don't have a canister plug it up. A hose from it to the oil filler will make oil come out of everywhere on your motor.
You might want to talk to the fine people at Airspeed about a breather system.
