Default ICP sensor blues

Well, it happened. My ICP (Injection control pressure) sensor started leaking oil from the HPO system. If you have an 03 6.0 you may want to remember this cause it will likely happend to you eventually.
Coming back from the lake 2 weekends ago it sprung a leak and coated the underside of the truck with oil. When i got home i saw the oily residue that had sprayed on the front of the camper so i look under then truck and about crapped myself when i say that much oil. I checked the oil level and it was fine so i hadn't actually lost much but t sure looked bad. I suspected either the ICP or worse, the rear main seal - which isn't usually a problem i am told. But the ICP is a common problem on the 03 models. Apperantly in 04 they changes this design and corrected it.
Anyway, oil leaks through the sensor and into the plug allowing oil to travel up the inside of the wire. So when you fix it you have to buy the wire harness also (which aint cheap) I couldn't reach the ICP to well as its located on the back of the block under the turbo so i called my diesel tech friend and he said he would do it and he could get parts at cost since he works for the stealership. So i took it over to his house and got it fixed. Parts were about 150 for the sensor and the harness plus an hour of labor.
What to look for? oil leaking, coating the underside of the truck. No oil on the topside in the valley. Look up on the back of the block and it starts from the ICP and spreads out across the block leaking down both sides. You might notice a power loss or the truck may die and then restart as i understand it. Mine had niether of these symptoms. No codes either.
Now i have several black puddles on the driveway to clean...

atleast it wasn't as bad as it could have been. you're lucky you were able to get just that harness. i've seen some hyundais in my day where oil has wicked so far up it made it to the ECM. that's a whole engine and body harness replacement right there.

glad you're back on the road.

Yahoo Is this my problem?

My 03 6.0L started leaking oil really bad! It doesn't leak when you start it for about 5 minutes, then it sprays oil everywhere! I have it narrowed down to the ICP sensor,( about 2 months old), or the hex-headed bolt or plug that is located to the inside of the ICP sensor. Any Ideas or suggestions from anyone?

my icp sensor started to do the same thing so i just put rtv on the threads of the icp and put a bigger resistor in the holes and used heat shrink tubing around it you have to have the right resistor but it just bypass's the sensor and adds about ten more horsepower and it costs about a buck vs a 150 dollar sensor and the truck will run fine i cant remember the resistor number but it is easy to find the directions on google

You all are lucky so far, mine wasnt so lucky ICP went out and didnt give any warning, it went out and the HPOP went out at the same time, kind of a double whammy, Visit the Stealership in Forida, since of course it happened while on vacation, 2100 bucks later new ICP and HPOP, and they also gave it back to me with 5 stripped out valve cover bolts. Nice of them I thought. Smell of burning oil filling the cab the entire trip back to Atlanta. Took it into Stealership at home and had to heliocore all stripped bolts at the Stealerships expense in florida just to get the oil leaks to stop and get rid of burning smell. Way to go Ford. I love the truck just dislike some of the mechanics they train.

This is not a smart idea, for SEVERAL reasons, and I would not recommend doing it.
