GN Grommet for pcv vent in to intake

Hi,

what is the right part number and/or dimensions for the intake grommet to the pcv vent? Car is 87 GN.

Thanks!

Hi,

I need the information above the issue. Again, Buick Grand National 1987 needs the new rubber grommet or what ever is the right name for it. The part in question comes in to the intake manifold and the PCV- valve will be pushed in to its hole.

So, I still need the right part number or some sizes for that rubber part.

Thanks in forward!
