What to do about leaking valve cover gasket?

My service tech told me today that my valve cover gasket is leaking and I should replace it and the Pcv valve... A couple questions; can I do this myself? Is this a bad leak? When I searched the forums, someone said it could be covered under the power train warranty, is that true?

Looks easy to me. Leak doesn't look horrible but it is getting around so I would fix it. Pull off your intake piping, and coils. Remove valve cover, clean surface, install new gasket with anaerobic gasket maker, install and torque bolts. Bam done.

Shake it around, do you hear a ball inside moving around? Can you only bow through it one way? If so, keep it! Or replace it do peace of mind since you have it off. And they're cheap.

With sufficient thrust, pigs fly just fine.

I'd tighten the valve bolts first, and see if that doesnt make the leak stop. re torque them to spec, in the propper sequence, clean the oil off, then see what it looks like in a week.

X2.

Check for correct tightness, then clean and reinspect. That leak seems pretty minimal.

You could just clean it with some type of degreaser (carb cleaner)

Mine started showing some oil around the edges a while ago. I just checked the bolts and they were all loose. I have no idea what the torque spec is, so I just tightened them by "feel", cleaned it real good and now, at least a year later have not seen a drop of oil.

New seal and new Pcv should be in to the dealer soon.

Attachment 198054

that is rtv to cover the front cover to the cylinder head seam, Keeps the joint from leaking oil in that area on the valve cover.

Is that using anerobic gasket maker in addition to the new factory seal?

Is this something I need to re-accomplish, or is it possible the silicone is still good?

Thanks guys, seal & new valve came into dealer today, should be doing this tonight...

So after getting the cover off, I'm sure it was the seal. Both the cover gasket and spark plug gasket were super brittle and "shorter" than their replacements. The new gaskets actually make contact with both surfaces before the surfaces touch. Buttoning up the cover now, we'll see if it still leaks.

put a dab of rtv back on those seam areas before plopping the gasket in place. Also use a torque wrench to tighten the bolts

Done and done! This time the cover rests higher than before, I might guess that the "loose" bolts are really a product of the gasket shrinking...
