Butch...
You said that ALL the heads are cracked under the injectors and the energy cells? Some heads or ALL heads? Diesels are known for being reliable. Doen't this bid against the diesel as being a reliable and desireable?

Can a crack cause an energy cell to leak and make a poping sound? I have been meaning to replace one of my energy cells that is poping and now you have me scared silly! I can see the black soot showing through on the end cap of the energy cell. I thought this was just dirt and I needed to clean and relap the outer edge of the energy cell. What is your take on this this?

I bleed orange but the 230-262 Buda diesels were as weak a motor as ever installed in a tractor. Improvments over the years made them better but the basic design had some serious flaws IMO. Link below should take you to my webshots page. The cracked head shown is from my WD45D and is typical of what a person finds when he removes the head from a 230 or 262 Buda. The cracks start directly under the injectors and energy cells and proceed outward. This particular head was cracked all the way out to the edge. Also note picture of removed energy cell, leakage is possible from two areas. The tapers on the outside of the cell seat in the head and can leak past. Also the retaining cap seals the end and they can leak there. If your is leaking from the cap that is easily lapped without removing the cell. If it is leaking from around the outside of the cell the seats need to be repaired, probably lapped also. Removing the cells can be a 14 carrot pain in the neck also. Notice tooling I made to remove mine. Recon heads, every one of them will be welded in some area, with new seats less valves and parts are a cool 1 grand per each with good core. and yes, when I said all heads are cracked, I meant it. Good luck with yours too.

Butch... what would you suggest... in reply to Butch(OH), 09-30-2005 05:05:41

Hi Butch...
Nice shots. So why do you think these heads are like this? What improvements would you suggest to remedy this from happening?

I make my own patterns and work on machine restoration work in my private time. If this becomes an issue, I will simply build a new set of patterns and core boxes and have a new head cast. So there is an opportunity to rememdy the design flaws by going down this path.

And I do have metal planers, metal shapers, milling machines and lathes including LeBlonds, Hardinge, Kearney trecker, Brown & Sharpe, Bridgeport, etc. So the machine work is not the issue. The new design and pattern work is the issue and does take time. But if its needed, well then, its needed.
