Hey there folks, hoping someone can help me out here. I'm totally puzzled. I was driving on the freeway a couple days ago and had just filled my tank about 15 minutes prior. (no leaking at that time) My truck lost power and enigine shut off. No bad sounds or warning. I pulled to side of road and tried to re-start. Nothing. I then smelled oil. Got out to find a huge puddle of oil under truck. Lifted hood and oil was everywhere especially in the valley. (manifold area) Towed home over 100 miles! Replaced lost oil. Truck would NOT Start. Assumed it was High Pressure Oil line at HPOP. The 3 o-rings that are so common. Those were fine. Took off the turbo to check O-rings on top of pedistal just to make sure, even though that area of the pedestal didn't seem to be leaking. O-rings were fine. I thought it might have been a loose oil line fitting, as one seemed to be not very tight. Re-assembled everything. Removed sensor from HPOP as when I cranked engine, oil pressure was not registering. (figure I threw a code or sensor was shorted due to all the oil?) Cranked on engine. No starting at all but now I see large amount of oil coming down right side of tranny area, appears to be from the top area still. Under or around where the exhause pipe comes down. Doubting it is rear main seal as those are so uncommon. Plus there is so much oil coverage in the valley area. I cannot see where oil is leaking from. (very steady stream of oil from just turning the truck over for about 20 seconds.) There is some lag time from when I stop cranking engine until oil leak is visable. Anyone have any clue? I'm about to have it towed to a diesel mechanic as I'm blown away after a couple days of this. Lost my job recently. Only mode of transportation. Don't have the money to pay a proffesional. ANY help would be much appreciated. Also, oil level is fine now after replacing almost 2 gallons. Fuel bowl topped off. HPOP oil level ok. However, I notice when I fill it, the level always lowers? Perhaps this is telling of an issue, as I understood it should fill to top and stay filled to top? Bottom line, truck will not start no matter what and is still leaking. Thank you all in advance!

 

sounds like when the metal gasket on the oil filter housing went out on my 02

 

I've heard of the plugs in the head for the injector oil coming loose. I would pick up a bunch of brake clean and douche it out real well and have someone crank it while you look. Everything sounds like to me, you have a definite hpop pressure issue. The back plate on the hpop could have failed or the gasket between the hpop and the oil resevior could have bit it. Good luck, hope this helps. Let me know what it takes to get it going.

 

Any updates??

 

Check the big round plugs on the front and back of each head.The ones in the rear are a pain to get at but it sounds like your losing hpop oil from one of those plugs. seen it so many times. symtoms are hard to no start, ecessive oil on the ground. Easy to reseal just hard to get the rear ones. Hope this helps.

 

If you have oil in the valley then its probably a front end issue. We had a truck towed in, customer thought it was the rear main. Turned out -

HPOP was loose on Drivers side
O ring on HPOP rear plug was shot. Took a mirror to find that one.

My guess, pull the HPOP, replace the gasket, and get an oring kit and replace the orings on the plugs. While the HPOP is off, check the gear housing for cracks or holes, but I doubt you'll find any.

 

My friend had a similiar problem with his 02 powerstroke. Its either the oil feed lines to the heads or high pressure oil pump
