Spent most of the day on a metal lathe, making a tool to flow oil/cleaner through the squirters. 90% done. Will hopefully post pics tomorrow if I'm done with it. It's kind of cool.
Tool passes through the case bolt passage, seals top and bottom, with o-rings to direct flow. It is threaded, and locked in place making it easy to use and push fluid through. Making the fixture really to be able to flow cleaner efficiently through the piston squirter, but can also be used to check opening pressure...
Catorce, respect your wealth of knowledge. Just sharing the results I found.
Will run through cleaner and see if it changes...

I personally think testing the opening pressures of used squirters to be useless. The opening pressure of the piston squirter is controlled by two things and two things only:
1. The diameter of the bearing inside
2. The spring rate of the spring, which is very low.
Take one apart, you will note that the spring is similar to one found inside a bic pen. It's really light!
Also, if you are testing pressures with air, you are WRONG. These open with fluid pressure. Yes, I know air is a fluid, but let's not get carried away.
Test with water.
Oh, and you should be testing brand new squirters.
