Did you use liberal amounts of silicone?
Customer: replied 5 years ago.
i did put any silicone when i install the oil seal. Do i have to put any? In addition i also change the valve cover gasket and have resealed the oil pan before we open the oil seal location.

Okay you will indeed want to use a liberal amount of silicone. Black RTV will do great.

Clean the oil off the seals using carb or brake cleaner. Apply silicone and small amount on the valve cover gasket as well.

Tighten her up and no more leaks will exist.

What if we put silicone and still the problem exist, what do you think will be the problem?
Expert:  proautotech replied 5 years ago.
The only way it will leak is if the hole is not sealed.

The seal alone never seals up between the valve cover and head without some silicone. This is very simple to add the silicone and I assure you it will stop it from leaking as long as you have installed the seal in correct way with the silicone!
