Hey, securityguy --
Have some questions about the air-oil separator. I was under the impression this is only for turbos; do these work in the non-turbo engines? (I have an '18 2.5 Forester)
The link you posted for the Mishimoto is, I'm assuming, what is to be used, even car's year?
I found one thread, where you posted a steel valve. Are there other parts involved you'd recommend?
What about installation instructions?
Does this need to be emptied at a regular interval? I have just over 18k miles.
Much appreciated,
Jonathan
