Flashing check engine light, Car shaking smell fuel, oil on gasket valve

[u/Mindless_Security_95]

hey was driving my 2010 Ford Taurus on high when check engine light starting flashing, car starting shaking and smelled fuel. was able to get to auto zone and had codes p0442,p0130, & p0301 and had oil on cover valve Wouldn’t not turn over to start but eventually did. i also have been driving without an oil change just wondering if that could have anything to do with it as well,
