Hey everyone, I just recently acquired a new set of 6.2 3 dot Inconel precups. After the initial magnet test and thorough inspection I noticed the edges of the prechamber opening are razor sharp. I've never seen a brand new set before, so this got me thinking... is it possible these sharp edges are part of the reason these cups crack so frequently? From what I've heard cracks like this are somewhat normal for diesel engines in general, and minor cracks aren't considered too big a deal, as long as they don't extend into the fire ring. That being said, would it be worth a try to use something like a small jewler's file or other abrasive to take the sharp edge off and eliminate the possible stress riser? Nothing crazy, just enough to soften them up a bit. Not sure if this is wishful thinking or if it's just a flat out stupid idea that will cause more harm than good. Any thoughts? I'm no expert in the area, so as always I appreciate any and all input.
Thanks in advance!
