2000 Avenger V-6 motor.

Any ideas how to install new spark plug seals. The new ones are the same OD as the old ones, the ID of the hole is smaller than the OD of the seal. The seals are a hard rubber.

Any ideas

 

You just use some gasket sealer to hold them in place let it set up then flip the cover over and torque down the seals fail and fill the plug tunnels with oil

I normally use the same gasket sealer on the valve cover gasket and let it set up at the same time while the O ring seals set up
