I posted here with pics of the underside of the 8.1L intake manifold,
I'm trying to understand how good/bad this closed internal pcv system is.
I don't want to reinstall the intake with the possibility of this being a problem, should i close it off and run a traditional external pcv system ?

Moved to a better section for you, should get some ideas here.

Also, please just make one thread per topic. Thank you!
