Yes, originally the pcv was plumbed directly into the intake manifold. Isn't that just a large vacuum leak, not to mention it sucks dirty air into the intake? That was why I switched the pcv to the air cleaner. I didn't think it needs full manifold vacuum to work properly. The manifold vacuum is now hooked up to my power brake booster. If I tee it at the manifold and have the pcv and booster connected will there be enough vacuum in the line?
