C-12 cat leaking fuel from turbo

Hi. Thanks for asking your question! I will try and help you out.

 

Most often this is a sign of either an injector failure or a cylinder failure. I have seen this many times.

 

When an injector fails it can overfuel an cylinder and cuase the fuel to come out the exhaust.

 

Also if a cylinder has a failure like a drpped valve, it will cause a lack of combustion and the fuel will not be burned. So the fuel will come out of the exhaust.

 

Please reply back if you need more help or have more questions. I am happy to assist.
