I'm in a process to replace the valve cover gaskets.

From the service manual it's written the following:

- Install the oil filler tube.
- Install a new O-ring seal.

With assistance, install the oil level indicator and tube.
-Install a new O-ring seal.

Therefore I'm looking for those O-rings but as it's looks like based on technical drawings those are not listed. So does someone know the correct part number ?
