Truck is puking oil

[roccodart440]

The truck always dripped from the inspection cover. This is not a drip and is not comming from there.

There is oil in the valley in the center of the engine. There is oil all down the down pipe and significant on the right side of the engine. Theopil seems to be comming from the top of the engine. There is no oil spraying around the engine compartment though.

Any ideas?

Also, it is not leaking from the dipstick.

Turbo o-rings maybe?

Or check the HPOS hoses on the HPOP. You might not get any leakin at idle (4-500 ICP), but as the throttle increases so does ICP.

What is HPOS and what is ICP?

High Pressure Oil System, the oil lines and rails off the HPOP. ICP is Injection Control Pressure, and it's the oil pressure from the HPOP through the HPOS. So it might not leak at idle. But once you get movin the ICP is alot higher, and it might start leakin.

It does leak at idle but it isn't spraying. Definily leaking upp top and towards the front.

I have to pull the fuel filter assembly off for starters to get a better view. Still don't get why it is blowing down the right side of the engine.

Everything that leaks into the valley comes down the back passenger side of the motor. Sounds to me like the two lines on your HPOP (right under the fuel lines into the fuel bowl) need new orings. The oil lines go into the oilrails on each head, might check there too. If those lines show any evidence of leakin at idle, they're gonna leak way worse drivin down the road. At idle they have about 500psi in 'em. Drivin down the road, it'll be anywhere from 1500psi -3000psi. So a drip at 500 = alot of leakin oil at 3000.

Make sense?

Right on the money chvyrkr81. It also needed new gaskets for the fuel bowl.

The only weird thing is ever since I got it back it cranks alittle extra before firing up. Is that normal? Air in the system maybe?

First thing... clean everything off real good. Let it dry and then get your buddy to start the truck and then watch...

You may even need to stuff paper towels into the valley to see where the oil is coming from... especially if it is coming from under the HPOP.
