What ways could gas get into the oil on a 04 f-150 lariat v8
You possibly have a leaking fuel injector.
Has the PCV been replaced recently?
A defective PCV valve will not put gasoline into the oil. Bad PCV might cause an oil consumption issue, but he either has a dead cylinder or more likely a leaking fuel injector. If that defective fuel injector fills the cylinder with fuel and an attempt to start the engine is made it is likely a bent connecting rod will be the result.
