Check your lug nuts AND tires for debris.

Ah.....just realized I also changed serpentine belt to a new one. Obviously tighter than what was replaced, maybe that explains it.

The correct-length OEM belt shouldn't introduce ANY vibrations into an idling car. Something else is at fault here; I'd start by getting those gaskets/seals checked out.

So reopened the valve cover again today and all gaskets were still in there. Replaced them with new ones. This time is took about a third of the original time.

Well that;s good to hear; but did you still have the vibration at idle? Is it felt in the steering wheel, brake pedal, accelerator, or in the seat through the chassis?

Just a subtle shake felt through steering wheel. But also, when it happens with the Ac on, when I turn off the Ac, it stops.

Maybe adding one of those steering dampers might help you out here.

Sorry, I didn't take pics of the steps. But can offer help if anyone decides to do it.
Hey man. I think I need to do the same procedure as one of my spark plug seem to be leaking. Could you please check out my post and tell me what you think? >> https://www.clublexus.com/forums/is-...-with-oil.html

Nope, just did it on the fly

sorry to bring an old thread back to life. Was there anything that needed to be reprogrammed after this? Or just straight forward remove valve covers replace gaskets and reinstall valve covers? This doesn’t mess with the timing at all does it?

No, that's all you need to do.

If anyone does this job, use a Snap-on bushing cutter to fold the edge of the tube seal inward and then use a small pry bar but first place a paint stir stick across the edge before prying up the seal you rolled over!

** Very important: when hammering on the seal cutter, back the opposite side of the cover with a firm piece of wood. **
