Okay Fellow PSD Owners, I am still Having an oiil leak from the back side of my motor on the divers side, I have became a Pro and Removing the ICP Sensor I have replaced it 3 times now cause it still has a oil leak every time i change it i look at the sensor to see if there are any cracks on the sealent that Ford uses to seal the plug to the nut itself, the last time there was no sign of wear but there was oil inside of the connection end of the plug. The truck leaks oil when it sets and i keep an eye on the oil level and still chang my oil and fuel filters on a regular schedule. Bascially i am stumped on where its leaking from. I am going to be doing a EGR Delete kit on my truck in the next few weeks and also a head stud kit at the same time any ideals where i could look once the cab is off for the leak ? ALSO what does the ICP sensor Screw into ?
