Im installing my egr delete on my 05 with 150,000. I got the intake manifold out and installed the part of the kit that connects to it. its the part with the rubber hose. the opposite side of the side with hose has a rubber gasket ring on it. i lubed the ring and inserted it into the manifold but for some reason it feels loose. maybe this is correct but i don't know. i also installed the plate that holds it in but from what i see it doesn't touch it it just keeps it from coming out. so is it being loose ok?
