60 series 14L high egt

I have a plug welded between the egr cooler and the exhaust manifold and have verified it's still there when I swapped my manifold a couple weeks back, I've also got a plug in the reduced section on the pipe where the delta p lines screw into that x over pipe.

 

I don't see how it could be a issue, the exhaust into the egr valve is blocked and the venturi exiting the egr cooler is blocked so no airflow through it at all.

I've got the oil lines that run to the egr valve blocked off and disconnected as well.

unless there is something I'm missing, I can't see it being a issue. I know the Cooler is very hot very quick but jut assuming it's from coolant running through it.

I'll look it all over again tomorrow to see if there's something I'm not seeing.

 

You can see I have the oil lines to the EGR valve plugged as well as the ports on the valve.



Inside this Venturi pipe I have it blocked with a large bolt with washers on either side, when I pressure tested it there was air getting to the too delta p line but not the bottom, there is no air getting through the Venturi into the EGR cooler and there is no leak at the delta p sensor from the air that is going into the top too delta p line.



And right here I have a thick metal plate welded and it is air tight, no leaks at all.

Valve guide seals possibly causing my issue? I'm going to pressure test just the turbo tomorrow and take off the oil in and return lines and exhaust from the back and see if it does anything funny at 31psi the pressure I build up is getting into the crankcase somehow in massive amounts and when I was pressuring it up and looking around the valves under the rocker cover , I couldn't see any air bubbles in the oil.

 

it should also be mentioned that I have low fuel pressure as well.

I put a brand new fuel pump on yesterday and it did not fix the issue of low fuel pressure. at idle I have 10psi whereas this sheet says I should have 18psi. same throughout the rpm range.

 

Just noticed this at my Davco. I know a little bit of bubbles is normal but I'm unsure about this here...... At first glance I didn't see any in my tank but looking very closely I can see bubbles coming back into the tank of my driver side tank, similar amount to what I see in the Davco here.

Gonna throw a sight glass on it tomorrow and run the return into a bucket.

 

Update: it seemed the bubbles on my Davco went away when I fueled up and came back when tank was low so I'm guessing a pickup tube.

I'm currently dead on the side of the road, engine shutdown due to low oil pressure. I checked my oil and it's way over full and smells of diesel fuel so I'm guessing I've got some badly leaking injectors, I knew they were not good when I redid the o rings last week, a few were pitted out and a couple seemed to leak but I was hoping to buy some time as I'm in framing one motor and putting a head on another. .....

gonna pop these injectors out at this pullout I'm at and the wife's gonna come get me, I'll be back in the morning where I'll swap injector cups and injectors to be safe... I went with Delphi from a injector shop last time but I'm gonna details the Detroit ones this time.

guess the leaking injector(s) could explain my low fuel pressure as well that I had.
