Re: Hello diesel Jeepers
Welcome to the forum.
The intake hose from the air box to turbo (includes pcv hose) gets saturated and leaks oil into the valley which then has a drain that runs down the back sides of the motor coming around and looking much like a rear main leak. You can pop this hose off and iirc you can look down into the valley to see if that is where there is an accumulation of oil, if so replace the pcv valve, and the hose "assembly", At work I then spray out the valley with brake clean and compressed air and viola.
