There is a oil/slight gas smell when I get into the car.

What is your question?

When I get into the car after it has been sitting for some time it smells like maybe burnt oil or a weak gas smell. Not sure where it is coming from. No engine overheating issues, no gas in the oil or coolant. I do notice that there are some greasy areas around the camshaft position sensor and near the intake manifold gaskets. Could this be an engine oil leak? Thanks
