Default What Is This Thing Above The A/C? It Is Drenched With Oil

Please help me identify what the shaft just above the a/c is, when viewed from the front of the car. Mine is covered in oil. In the picture below, it is above the a/c and protrudes left past the serpentine belt. Thanks.

I think that is the oil pump. You may also want to look at your valve covers as they may be the culprit, and I've read somewhere when they leak they leak profusely.

That is the control valve for the hydraulic fan pump, which is mounted in front of the water pump.

Thank you.
Are there some o-rings on the control valve that can be replaced or do I need a new control valve? I think the part # for the control valve is Lexus 16929-50020.

16929-50050 is the newest part number for the control valve, however it is discontinued.

90099-14114 is the o-ring between the control valve and the housing. 90099-14115 is the o-ring used in the plug just below the control valve.
