Suspension have any fluids???? Never knew and never heard of one. Good find for me.

If its very very mild noise then i suggest please forget it, as more cautious ear you give to your ride, you will assume and hear 100 things.

If ever something will go wrong, then you will hear it loud and audible decibel level then you can think or know yes this is wrong. These minor things eventually get you spend too much on guesswork, where you might know in end it is normal and every car and every LX have that small noise here and there.

maybe its coolant mixing into engine oil.

See the quality of the Oil.

The crankshaft position sensor may have failed, the wire or connector in the circuit could be grounded/shorted/broken

It could be a blown fusible link or the starter that must be damaged.

it is also advisable to get a mechanic to check it in case you get lost

it is good to start with the window fuse. and motor

it is ok to drive but u must get it fixed ASAP and drive slow on curves and otherwise

The Cold Start Injector of you car is mounted to the bottom of the intake air chamber.

Lexus Motor Oil 05 W40 is what the Lexus Manufacturers are recommending. this is available at all Lexus Dealers.

Sounds like unburnt fuel is escaping. Check if the injectors or fuel pressure regulator are leaking. Get AFM computerize check to make sure its fine and not freaking.
