So I've always just bought injectors reman'd and had good luck.
They used to be cheap, progressively not so anymore, and I got a good deal
so I bought a pop tester.
Been mucking around with it, I have a pile of play-injectors and four new nozzles too.
The ole gallon cans of carb cleaner make damn fine injector cleaners if you have a few days to let them sit,
crack em open, loosen the nozzle in the housing (careful tap) and they come out such that the carbon wipes off
with a rag. Neato.
Now, testing these things. This strikes me as kind of an "art" and desipite a lot of reading I'm second guessing myself
left and right.
I tried one out of my old TD from many years ago, obvious crap, bad pattern, leaked @1500psi, text book bad.
Great.
I took one of my cleaned bodies, lapped the mating surfaces with 1000 grit till smooth and popped in a new nozzle.
After a couple settling in pops, it sprays well. I think. It might be my eyes, and the little cloud of diesel vapor that immediately
obscures one's view after the first spray, but it looks like it's ever so slightly biased to one side of the stream.
Or it might not. It's pretty damn hard to tell.
It's also popping a hair high, 1900 depending on how one strokes it.
That isn't unusual after lapping, higher pop, I read.
Which is another thing. It seems to me that the method of articulating the tester handle can effect the
pop pressure a bit. I can make this injector "pee" if I try to. Should I be able to?
Is it proper to use short "pops" and kinda try and see where the needle does not climb at
or run through a steady long-pop and see where it holds throughout the duration?
There is variance here I'm not loving.
And the return ports, should they leak? I was holding pressure, with occasional handle movement, to keep it around 1500psi
looking for body leaks, and it started weeping out the bypass ports eventually.
Should it? Kinda hard to throughly check for body half leaks when it's running down from them, I capped them but that wasn't sufficient,
need to cap one and run a drain line on the other I suspect.
Am I being too picky here?
