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!

09-23-2013, 12:54 AM #1In 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

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...
