Oh Crap, I recently noticed a light tapping noise sounding like it is coming from the bottom end of the engine when warmed up. Possible engine bearing issues. I use Mobil1 syn every 4k miles. Never checked for sludge issue, but it never leaks/burns a single drop between changes. I guess it might be a exhaust leak or loose spark plug, but this makes me wonder. This weekend it will pull a valve cover just to see what the sludge issue is if any. Then try to pinpoint the tap noise. Might be trading it in soon if it is what I think it is. 104k miles. I love this RX300!

Look for broken or leaking flex exhaust coupling.

This is what Salim is referring to below.
Injectors can make a tapping noise when cold and when the engine has higher mileage.
Another area is the accessory belts, especially when cold (I notice this) can make a tapping sound.

Thanks, I will look into it. The problem is when it is Warm, not cold. Trust me, i sure hope it is an exhaust leak, but I am no rookie when it comes to working on cars and this noise sure sounds like an internal engine noise. I will post this weekend what I find when I get a chance to look into it. Not looking like a valvetrain noise either.
Thanks.
Thanks.
