Gotta get right on this. Fuel in oil suggest injectors are dumping fuel too much when running or leaking badly when shut down diluting oil which quickly with be excessively thin and could be the noise! That's like piston wash and can cause rapid wear that you don't need.

It doesn't take much gas to thin the oil but you might find oil a bit too full and this is an emergency to isolate and fix - so don't wait too long to find and correct. Possibly injectors themselves can't/won't shut tight,

These motors are bad about the fuel pressure regulator leaking. About the right mileage for that to start happening. The regulator is located under the upper intake so when it leaks the fuel will leak into the lower intake causing the motor to run poorly. It will make a bunch of rachet till all the extra fuel is burned off. Dose it take several cranks to start when you try to start it for the first time of the day?

No it doesn't when i start my car it turns on fine with no problem,the noise starts as soon as i start the car,and after five minutes of the car running the smell of gasoline starts but the noise never goes away only if i turn it off,the noise is like a tactactactactac.
