I am coming up on the 60k and the manual says to adjust the valves. Picked up valve cover gaskets from the dealer today. Will I need a throttle body gasket? Anything else? The tappet clerances are in the owner's manual. How many hours does it usually take?

Adjusting the valves is the easy part, the time consuming part is moving the intake, valve covers, etc. Might as well change the plugs while you're at it.

Will do on the plugs. Does the intake plenum gasket get changed when you do this? Can't find an intake manifold gasket for the 3.3...

I believe it's an O ring type gasket and from what others have said, they just reused it.

Pardon my ignorance, but is it really worth tearing down the top of an engine that is running quietly? The footnote in the manual does say "inspect for excessive tappet noise and/or engine vibration and adjust if necessary"

I used to check valve clearance religiously on my motorcycles, and the only times they ever needed adjustment was when they had become noisy. Even then, a little bit of slop was not considered harmful. The greatest risk was over-tightening the valves, followed by dropping crap into the engine or damaging a gasket during the job. Over time I learned to do the adjustment only when a clicking noise - more pronounced at all RPM than the idling fuel injector noise you hear on a Santa Fe - had developed.

Having had many motorcycles - we fussed with such things every few hundred miles. No one but a BMW R60 owner went 60k miles on a bike in my day.

At 60k it does not strike me as overly fastidious to follow the owner's manual and adjust the valves, and as suggested above, throw in new plugs. I have purchased the VC gaskets so this issue has become moot at least for me

Exactly and the 2007+ 2.7L and 3.3L V6 do not have a typical jamb-nut type lash adjusters. Read up on it. Hyundai calls them mechanical lash adjusters, but they are pretty much shim/bucket adjusters. It's a direct acting setup where the cams sit right on top of the valve stems (no rocker arms). In order to "adjust" them, you first have to measure between the cam lobes and MLAs with a feeler gauge, then tear down the entire top end, removing the camshafts, pull the MLA's and add the appropriate sized shims (washers). This is essentially a shim/bucket lash adjustment system. I surely wouldn't touch this on a ~3yr/old vehicle with under 100Kmi. Definitely not on the chain driven cam(s) 3.3L. The chain has to come off along with everything else.

Thanks Joel, I guess I will leave the top end alone

You could still pull the cam covers and check all 24 with a feeler gauge if you suspected an issue. Then again, in order to remove the rear cam cover you'd have to pull the intake manifold to gain access to the sparkplugs, etc. Lots of work. I guess in the end, these shim/bucket systems are designed to last the life of the vehicle. You'd be better off installing a whole new set of loaded heads on the engine than mess with them!
