No injection pressure 6.0

ken6881 · Sep 19, 2013

I have a 6.0 that just had the head studs, egr delete and now it will not put out any high pressure oil. It will pump up the oil filter housing but it does not put any high pressure oil out. I pulled the ICP sensor and can see air in the rail but when I crank it no oil comes out.

Anyone have any ideas from where to go from here. I am about to pull the valve covers and see if I can find a High pressure leak.

thanks

Air test it at the ICP sensor port.

Just put pressure on it?

ken6881 · Sep 19, 2013

Seems to be no air leaking. Nothing comes out the valve cover vents

Any more ideas I'm at a loss

a video of cranking looking down through the head

Looks like there is air coming through it?

Can this be done by making a fitting adapter and replacing the sensor with said fitting then pressurizing?

Stand pipes and dummy plugs in the correct holes?

ken6881 · Sep 19, 2013

yeah the holes they came out of.

reilly8282 · Sep 20, 2013

Pop the dummy plugs out of the front just to make sure. Easy check, and easy mistake.

Probably just needs the air bled out of the system? How long have you been cranking it?

ken6881 · Sep 20, 2013

Yes there correct I have already pulled one rail looking for a problem. And i have cranked it many times I would say 5mins total of cranking. Is it possible where the stand pipes plug in down in the motor has came disconnected from the pump?

reilly8282 · Sep 20, 2013

Maybe possible they are not seated correctly, only way to find out is pull them, then pull the lower portion with some long pliers out, reconnect them outside the motor, then put them back in the rear ports of the oil rails.

5 mins total of cranking?? its going to take more than that. if you have some help you can take the icp sensor out and crank it over till some oil comes out. that will help bleed some air. its still gonna take some crank time.

ken6881 · Sep 20, 2013

How many times of cranking 30 sec at a time should be seasonable.

ken6881 · Sep 20, 2013

Well I fill like a dumba$$ cranked it one more time for 30 sec with each rail opened up and bam oil everywhere. Truck fired right up hiccuped 3 times and never missed a lick after that. Thanks for all the help.
