I believe you need to remove and install them from inside the cover.

This thread has some good photos showing the tube seals:

Yup, those get installed by pressing in from the backside of the valve cover once removed.
Usually done when replacing valve cover gaskets.
Perfect time to replace PCV & grommet as well.

The spark plug tube seals are installed from the inside of the valve covers. You don’t need to bend the retainer up tabs either to install them. I have no idea why Toyota recommends that, totally unnecessary.

I did a set last week, lubricate the seals with motor oil and they pop right in, finish setting them with a socket.
