D19 energy cell replacement

About a month ago I asked about energy cell repair as I have a neighbor that had recently purchased a D19 diesel. As he looked over the tractor before the purchase he thought it was just a manifold leak. The previous owner had completed a restoration of the tractor including a out frame engine rebuild. The tractor has about 9 hours on it since the rebuild. It was obvious that he had been fighting several energy cell leaks after I removed the intake and exhaust manifolds. Attempts to stop the leaks included a copper crush washer under 2 of the 3 energy cell caps. Anyway, there is no information on the internet for this repair. After some discussion on the forum, I want to thank AC-Mike for some advice he gave me as well as some pictures of the tool he made to lap the cap. In the end I made a change to the lapping tool to match the new caps I ordered. I want to emphasize that this was a totally new experience for me, I may have not done everything correctly or as others have done but the end result was a good running tractor with no energy cell or manifold leaks. The tractor now has a few hours on it and all is well so my neighbor is happy as well as I. The purpose of the video is to show everyone what a energy cell and cap are, how to remove them, how to install them, the lapping procedure, and just to see what I did to solve his issue. Unfortunately, we began to get a hard rain during the video so the noise in the background is the rain hitting our tin roof on the farm shop. I’ve never made a video before and was quite nervous. I also cleaned up all the original air cleaner parts and painted them PO#2. The previous owner had installed a aftermarket air cleaner. I want thank my brother Charlie for shooting the video. Also need to thank AC-Mutt and brother Jim for helping me get the manifolds and original air filter system back on the tractor. Much easier to do with a extra set of hands.

good how to video ,   my question is if the energy cellwas cracked or had a hole insidebut did not leak outside where would combustion gasses go to   cooling system or crankcase or back to the cylinder ?

There would be no where for it to go. The head area where the energy cell is, is solid casting.

You did a great job. 

Thanks Mike, that means a lot coming from you sir. I really appreciate your advice. Correct me if I’m wrong Mike, but it is a indirect injection system. Fuel is shot through a head passage from the injector on the opposite side of the head. The fuel enters the energy cell and is repelled by the concave in the cap, pre ignited and then sucked into the combustion chamber to combust. My understanding was a cleaner burn of the fuel and was more efficient. It must work well because my D17 is very fuel efficient.
