The first thing to look for would be an exhaust leak. Check for a fuel leak on the top of the engine.
Smell the oil, if smells like some gas is in it. then it would be ur fuel pressure regulator.

sounds like you use a bad mechanic a good mechanic would replace a cracked exhaust manifold to start with if you can smell gas,there is obvioulsy a leak in the fuel system. this needs to be found as it is a fire hazard
don't ever smell your car's exhaust.
I would start by checking any leaks in your exhaust and fuel filter area, if there is any leaks throughout the exhaust the smell of gasoline or exhaust may come through into the interior.
i had a fuel leak
The carburetor needs calibration or changing of possibly defective part, for example, gasket or needles.
Yes, a catalytic converter can influence the smell of exhaust fumes. If the converter is functioning properly, it helps reduce harmful emissions and can eliminate some of the rich, fuel-like odors. However, if the catalytic converter is failing or there's an issue with the engine, such as incomplete combustion or fuel mixture problems, it may lead to a richer smell in the exhaust fumes. In such cases, addressing the underlying issues can help mitigate the odor.
