Valve cover gasket replacement, How to? Options

[GotToyota]

I'm pretty sure I need to replace the gasket on my valve cover, as there is a slight amount of oil on the #2 and #3 spark plug, plus I have a small leak. Is there a how-to on how to do it? I'm gonna try to tackle it this week since I'm off for spring break. This is for a 5S.

Replacing the gasket [should] solve your leak, but it won't fix the oil in the plug holes.
For that you need to reseal [or possibly replace] the spark plug tubes, which is a PITA.

When you install the new gasket, you ONLY need sealant on the corners of the cam "humps". You don't need to smear it anywhere else.
The Toyota stuff works great, but is expensive.
You can use black Permatex silicone, but you'll have to wait overnight for it to dry [the Toyota stuff drys in like 20 min].
You might want to replace your PCV valve and grommet while you're in there.

PB Blaster works great [better than brake clean for stubborn stuff] to clean the valve cover.
Spray it and let sit for an hour or two, then use brake clean to get rid of any residue on the sealing surfaces.
You want to clean ALL the old silicone off before you reinstall the gasket.
