Oil Squirter Opening Pressure Test Info

Test results: Using my High Tech test rig (Hose with a squirter screwed in hooked to the mini reg) They start opening at 39 psi and full open by 48 psi.

I tested 3 used squirters and they're all +/- 1 psi.

A bit more info ;)

While I had all the parts out I made a test fixture to test the "opening point" of the oil squirter "Check Valves" as Toyota calls them. These items are a bolt with a ball bearing held pressurized with a coil spring in the closed position the oil exits similar to the way oil would exit a banjo bolt. If you have been following this thread chances are you know all about them. Heres a photo of a set of new ones.

Most of the ones in good condition seemed to open above 45psi and all seemed to flow at least a small amount as low as 10 psi. Obviously I was testing with air pressure, so it is highly possible they flow nothing until their designed pressure release of above 45psi with oil behind them. Watch the videos I find it very interesting to see how they actually operate when tested.

Heres a photo of my test rig, very simple actually, but seemed to work great.
