Starting up my 35

Well I have the engine finished and back in the tractor but I am getting compression leakage around all 3 combustion chamber caps. I installed them with new copper gaskets but it looks like there may have been an o ring on them also. There were no o rings in the gasket kit, has anyone run into this before.

I am also having trouble getting the injection pump to prime. I have a new lift pump and I am getting fuel to the injector pump but nothing to the injectors.Does anyone have any suggestions?
On a good note I have 60 lbs oil pressure with the starter.
 
Those plates could be warped a little, just enough so they won't seal. With the amount of compression diesel engines have it doesn't take much for them to leak.
 
I always open fuel shut off control (Rod to Fuel Pump)...
Loosen all three fuel injector fuel supply lines at fuel pump..
Open hand throttle.....
Hand prime Transfer fuel pump until all air is removed from Filters....
Open one bleeder valve on main Fuel pump until air is no longer present,close bleeder..
open second bleeder valve on main Fuel pump until air is no longer present,close bleeder..
There is a NOTE in the service manual as to the order of bleeding the bleeder screws on the fuel pump....I'm unable to recall the order?

Crank engine on Starter,and continue had priming ...when fuel is present at point were lines attach to fuel pump,tighten fuel line...
I've had to crack fuel lines at Injectors ...

Two tips I'll add, check the constant bleed orifice fitting on top of the final filter, and make sure it's not plugged. It's designed to remove any trapped air from the filter BEFORE it can get to the injection pump. When it's plugged, and any air gets to the pump engine will shut down. Fitting is usually connected to the injector bleed off return line. Second is to have the injection lines tight at the pump, but loose at the injectors to get the air out. On engines I've had apart I also leave the injectors out to bleed the fuel system easier and also bring oil pressure up faster since the starter has less cranking load.
 
One more question, how long has it been since the injection pump worked? If it's been awhile it may have the metering valve and plungers stuck from setting, and will never work until it's torn down and cleaned of stale fuel inside. I've been repairing more pumps like that lately. Any traces of water in fuel, or bio diesel will guarantee internal parts WILL be stuck. Bio diesel I've seen built up so bad the governor weights won't even fall out of the weight cage..
 

It has only sat for about a month I have fuel at the pump bleeders, I annealed the copper gaskets on the combustion chamber covers and reinstalled them with a generous coat of K&W Copper Coat. I am gonna give it until tomorrow to set and try again. This is giving me time to make my alternator brackets. I will leave the injectors loose until I see fuel at the injector lines then I will tighten the injectors hook up the lines and try again
