I am completing an overhaul of my 1994 530i intake system and trying to re-install the PCV tube which runs under the intake manifold and connects to the PCV plate at back and into another tube at front.

I did not notice when removing the tube, but it seems like I can have only one side fully inserted on either end, leaving one side apparently coming up short. Is this normal or am I missing some important tidbit of info?

Thanks,
Ernie
