So, you are saying that there is a kind of poppet valve for the oil squirters?


Yes, most all engines with squirters have a valve in them.
In the Mitsus they close the flow about 30psi. I expect they vary from that some.
They are aimed to sweep the underside of the piston dome.
I have seen them in NA engines from Nissan and Mazda too.
