No, I don't mean the check valve into the brake booster.
The hose is tee'd into the pcv line at the vacuum block, then goes through a small inline filter, and then to the check valve on the brake booster.
I thought TTA's didn't have this filter.
Can anyone confirm this?
FROST -I've been running with no filter for 7 years now on the GN. The hose goes directly from the aluminum vaccum block on the throttle body to the check valve on the booster. No problems so far, so I guess it's ok? dunno
