Does the engine oil smell like fuel? You can also use a rag and a blowgun in the filler neck and try to pressurize the fuel system. Then look for leaks in the fuel system.

 

no fuel in oil.

 

Then you are going to need to get the system under pressure and look for leaks. It won't take much pressure to see where the problem is.

 

thank you very much

 

No problem did you find the problem yet?
