bloc
SILVER Star
It’s just a foam block squeezed into and around the SAIS piping and pushing up against the bottom of the manifold. Plenty of little gaps for them to enlarge via chewing.I didn't get the impression that there's much ingress there. Have never looked closely...but maybe someone wants to drop a snake camera in there. It's already too late in the day to touch vehicle here, or I'd do it m'self.
Maybe we can shrink one of those Chinese machine gun dogs down and have it patrol as sentry in the valley.
