Also, if a Porsche squirter has in fact failed in open mode, and dribbles at idle... how much effect on oil pressure is that? Your post suggests it likely isn't much.
And just as an educational point, since I love to learn, whats the damage if a squirter is stuck closed? I ask as it seems lots of folks find stuck squirters on disassembly, yet nothing bad happened? Is the issue accelerated wear? Detonation? Faster wear on the rod short end bushing? All of the above?
Thanks!

Bo,
My squirters will be available within the next week or two; I am also currently making an install video as well so that is taking some time. They will be ready LONG before the cases because I am not just sitting idle while the cases get made, I am introducing other ancillary products, the squirters being one of them.
They don't fail open to my knowledge. What they actually do is dribble, then driblle a little stronger, then when the pressure required to move the check valve open happens, they make this weird noise (like a hornet buzzing) and they burst into a spray pattern.
My guess is that as the squirter ages, contaminants in the oil slightly delay they opening of the check valve.....SLIGHTLY. Just gums up the works a little.
As to the effects of a stuck squirter, I won't pretend to know all of the ramifications involved with that. I don't really see any written data on the point of a piston squirter other than to cool the bottom of the piston; early 911 engines didn't even have squirters, which implies that they did not need them for lubrication purposes.
The real effect of a dead squirter should be increased combustion chamber temperatures, which of course diminishes performance.
