i have 2004 chevy epica that had gas in the oil after changing the oil the car doesnt seem to be getting any spark does anyone know what might be causing this
I would think that the fuel injectors are dumping too much gas into the cylinders. That's really the only thing that I can think of that would cause gas in the oil.
Another idea just came to me. Might be piston rings. A compression test might be able to narrow that down though.
