Hello, I have problem I've been chasing and need help from gentleman like yourselves. 7.8L Duramax 6HK1TC I'm having fuel slowly fill my oil pan up (about 1/2 quart per week) and I can't find the source. I have replaced all injectors and the fuel pump already. Do any of you know where else the two could be coming into contact with one another on a 7.8L? I'm leaning toward pulling the valve cover again and inspecting the fuel return line once again, other than this I'm out of ideas... Any help would be appreciated.
Thanks
Thanks
