Howdy ...

Easter had me tied up. My bad.

That pitting ultimately does not mean anything in regards to the health of the nozzle. I have seen them really pitted, and they popped just fine. I have seen them perfectly flat, and thought bingo found a nice, unused one and it peed like a race horse. I know folks go on their jihad about nozzles having a blued color or rainbow colors and those nozzles are toast. That is most likely true, but I found those which appeared to have been in a kiln, but they popped great. So, the moral of the story is pop test everything. You might be surprised. I even had the various self-professed know it alls on Peach Parts who claimed that stuck pintles ultimately mean not worth your time to tinker with, and I have soaked them in PB blaster or tranny fluid and acetone and guess what ... some of those worked great too once you got them cleaned.

I believe the key is getting all your injectors parts and internals super clean. That is your starting point. Once you get there, then it's hit or miss. You have to pop test them to see what's up. I have had NEW nozzles initially pee a little because they had some sort of metalic grit inside them from the factory. You need a lot of shims since your PSI is also crucial.

As for used nozzles, who knows until you test them. I test used nozzles in batches of 50. Sometimes I will end up with ZERO usable used nozzles. Sometimes I will end up with a whopping 5 or 6. Normally, out of 50, I will get 2 or maybe 3. Before I test them, they are super cleaned as cleaned parts is the KEY !

Sorry for the long winded commentary, but this is not intended to be the end all explanation or definitive guide to nozzles or injectors. I have just learned on other forums, especially PeachParts, there is a small contingent of folks who seem to want to disagree or debate every little topic, ranging from changing your oil to adding washer fluid to the resevoir bottle Or they simply know everything in the world about cars. Interestingly, most of those folks have about zero experience on the topic or they claim, back in the day I used to do this or that a half dozen times ... blah blah

Hope the above helps.
