Ever Seen This? Broken Pre Chamber... - Captain America - 09-23-2013

In light of the Prechamber Mod "Flame" Front thread, http://www.superturbodiesel.com/std/thread-2169.html , I finally gathered the tools and pulled all the pre-chambers out of the 1985 head that I have. All came out easily and I had removed the glow plugs just prior. I was super stoked to see that the '85 had the "Up rated" prechambers with the larger "k" and "L" holes

   

I got sad though when I pulled #5 chamber and saw it was broken...

   

   

Has anyone ever seen this?

Guess I'm back to pulling my current chambers and reaming them, But looks like a lot more reaming is to be done to the up rated chambers anyway!

Yes. Common issue... Makes a lovely noise Wink In worse cases the "swirl pin" (don't know the proper english term) cracks open the pre-chamber and creates serious damage to the engine...

Dunno if you recalled the glow plugs I pulled from my first motor winmutt, but the ends were all gone and I was scared of things looking like those

I've seen it, it killed 2 cyl on an engine I had. The turbo was junk also, engine still ran fine...
