2000 ES300 valves question
Does the 2000 ES300 have hydraulic valve lifters?
I hear a valve tapping when the engine is cold and wonder if valve adjustment is needed?
The car runs great otherwise.
(looks like from the '97 manual that the lifters use shims?)

Valve adjustments on this car are part of the regularly scheduled maintenance. I'm not at home now and don't remember off hand at what milage Lexus recommends that they be done, (I think every 60k miles)
If you have your owner's manuals it's mentioned there, or someone can chime in and provide the exact milage requirements.
On the other hand I don't know of anyone that has actually done it, but many probably have.

I don't know if this engine has 'lifters' (hence my question). The valve tapping noise occurs when the engine is cold - after it warms up, the sound fades away. This just started about 2 or so months ago.
From what I have read so far, the engine uses shims to gap the lifters properly.

i too had this noise for like ages but no problem in driving or performance. It was Lexus mechanic and people here @ CL that told me they were dealing with lifters and said to check for them/repair is an expensive labor and will take lot of time. To reduce the noise try switching engine oil to different brands and see if the noise subsides. It has happened to me
However in my case the noise is there when its warm. Here i had taken a video. tell me if the noise is similar to what you are having. (check the video description for specific timing)

The car has 93,000 miles. I am the original owner. The oil has been changed every 5,000 miles with 5w-30 Mobil 1 for the first 70,000 miles and 5w-30 mobil 1 high-mileage thereafter.

Now, if this just started 2 months ago, might that correspond to an oil change? And I am not sure if you mean it taps just until oil pressure is reached (within 5 seconds or so) or if it actually takes 5 minutes. Oil filters with leaky anti-drainback valves are notorious for long oil pressure build up when starting a cold engine.
Also, is there a possibility that you are hearing a fuel injector clicking rather than a valve? Sometimes injectors can get noisy.
