2004 6.0 oil leak from rear of motor (2003 motor)

Noticed a small oil leak back in January on my truck, and thought it may have been just excess spilled from a recent oil change. Then as the days and weeks progressed, the leak got worse.. Crawled under and noticed it coming from the top rear section of the motor, with a stronger drip on the driver side, with a few drops coming from the passenger side, leaking down the tranny. Now it is a steady and heavy leak, but only begins to leak as the truck warms up. does not leak from start up. after about 5-10 minutes at idle, it begins and worsens as the motor heats up. Changed driver side valve cover gasket thinking it may have had something to do with it, but it didnt solve the whole problem. Any help would be appreciated.

ICP sensor

Replace the sensor and the pigtail

Well just take a look at the sensor before hand. A few of them have been known to leak

Any way of getting a better view of it without pulling everything apart? I heard 2003 motors have a easy access icp sensor that you can get to from under the truck...

I have the same year, its your ICP. Mine was doing the same thing. You have to pull the Turbo to get to it. At least that is what I did. Good luck.

You dont have to pull the turbo...You can get to it from under the truck. Removed the rear heat sheild at the top of the motor, and you will be able to see it. I use a cut down 1 1/16 wrench to remove them and replace them. All said and done its about a half hour job once youve done one.

Easiest way to remove the heat shield is also from underneath? or take it off from the top?
