possible blown Head Gasket

[2Fast2Furious]

there is no valve cover gasket mentioned on the Toyota document as you can see;

I will ring Toyota tomorrow for more details, like ph etc;

this is were the leaks are according to first mechanic;

are there 2 valve cover gaskets?;

when replacing the valve cover gasket will I have to do a valve adjustment;

these seals are they spark plug tube seals or what about them;

do I need to order 2xseals for gaskets?;

what about grommets?;

what tools am I likely to need?;

should I use sealant and what type?
