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...
