oil leak

[cr125rider1988]

it apears that on my 97 powerstroke mason dump that oil seems to be dripping pretty heavily out of the thin cover over the flywheel. along with that the passanger side of the motor cant really pin point the leak.... but i dont want to drive up to a customers house and leave spots of oil. Anyone have any ideas?

It could be many things (and it could be either fuel or oil elated, so make sure). The valley of the engine has a drain path to the passenger side rear of the engine, so if there is any leakage up top in the valley it will drain there. In the valley, look for oil leaks at the High Pressure Oil Pump (HPOP), Hoses, and fittings (both at the pump and where the fittings go into the heads. There are large plugs on both ends of each head that can leak, there are o-rings at the turbo pedestal on the block side and the turbo side that can leak. The Exhaust Back Pressure Valve (EBPV) actuator cylinder can leak as well. Then there are many fuel leaks that can occur. Fuel leaks many times will look like oil by the time it picks up all the grime on its way to earth. Cheers!

ok great i know for sure it is not fuel i have smelled everything on the ground and not a hint of diesel in it. in the valley it apears to be very grimy but no puddles of oil. The tranny (e40ed) was just replaced with a new rear main seal, not sure why it would be leaking out of the cover covering the flywheel.

I just kinda run into the same problem with mine. Mine happened to be my dip stick tube at the very bottom. The piece that goes into the oil pan. Check that when u get a chance. Hope this helps

Mine is having the same symptoms. It's pouring down the block to the starter area. I'll check some of the areas mentioned above and report back. It is definitely pressurized and will leak a gallon out in no time. Thanks in advance for the help.

With a little better lighting I've identified that the leak is likely originating near the front of the engine in the valley. I can dry up the oil in the rear of the valley, and when the truck is running it takes a couple of minute for the valley to fill again and spill down the back of the engine. I cannot directly see where the leak is. I'm hesitant to pull the fuel bowl, hpop, and reservoir off just for giggles. What course of action would you guys take?

Most likely an o ring on one of the hpop lines

Are those the two connections that lead to the valve covers? There is a bit of oil around the connections at the pump, but they don't look wet enough to be causing the flow towards the rear of the valley.

[Fordman247365]

My advise, pull the fuel bowl out. It is held on by 2 bolts and the 3 fuel lines to the pump (replace these while you are in there, if they arent leaking they will be) once the fuel bowl is out of the way you will be able to see in there a lot better to see what you have going on. Hpop lines dont have to 'look' very wet at the o ring to leak bad, lots of pressure in there

Also, there are 4 plugs on the valley side of the heads that also have orings on them that can fail, and so does the fuel pump. Could also be the hpop gasket itself.
