Hey guys, quicky question.
I searched into disassembly/inspection and rebuild/cleaning of injectors as I suspect I may be having issues with them after my last test drive ( that and unknown engine history/mileage+sitting for 4 yrs).
Once satisified I knew what to do, I took the old injectors out of my blown 616 to experiment on before I dig into my car, upon disassembly, I saw what first looked like a carbon deposit in the tip of the pintle that protrudes thru the end of the nozzle. After trying to rub it off unsuccessfully I got my dentist pick and probed at it, only to discover it's a little hole, found one
180* out from that one as well, was able to pass a very very fine precision drill (about human hair sized) thru the hole to clear it out.
Now my question:
At the very tip of the pintle, it looks like there is a hole that tees into the other one, but I can't seem to run anything thru it, is it just an indentation or is it really a tiny passage? I assume it has to do with the proper atomizing of the fuel, so if it's a hole I will need to address cleaning it.
