Does anybody has an issues on 2007 RX350 - 54K miles with noisy engine comes off from crankshaft bearing, water pump or valves train..?
My car just has constant noisy engine issues about 5weeks ago, and it won't stop...It happens when I start the engine even it is in idling or in driving...
Whether it is a cold day or hot day...Noisy engine sounds like knocking and grinding noise metal contacts...I use Conventional dealer 5W-30 / Oil change every 5K miles...I just do the oil change and it does not help...

Get it checked out if it is that loud, you can be doing more damage by not taking care of the issue. It's hard to diagnose noises over the internet based on a description. Might be a pulley to internal to the engine. Have a local Lexus dealer or mechanic look at it.
