My parking garage hates my car

Hi, This has turned into a real problem. It has been this way for the almost 2 years I have had the wagon, but the facility guy here at work came up yesterday and said that they might not let me park in the underground garage any more. And parking anywhere else here in Santa Monica is a real pain.

The Wagon smells of gas when I fill up the tank.
How do I figure out where it is coming from. I am wondering if it is the tank or the filler tube or something else.

They also said it leaked oil, which I put cardboard down this morning to prove it did not.

And they say it smokes. Which it only does when cold.

Any ideas on low budget/DIY fixes?

Personally I think the guys here with Bentleys, Astons and Porsches are just jealous.

Maybe the seal for the filler cap?
