I'm looking for suggestions on my 2010 LS460….Rwd…26k miles….
My wife was in Arizona a few weeks back, and had the bad luck of getting caught up in a flash flood just west of Scottsdale. Unfortunately the 4.6 inhaled some water due to a huge wave kicked up by a passing truck while she was fording through some wheel deep water. The engine died and the vehicle has been trucked back home to California. I had it initially inspected at Lexus and it seems like we probably have some bent rods as the engine will only turn over by hand partly before it comes to a point and locks up. I have yet to have the engine removed for further inspection until my insurance adjustor can see it. Nothing got wet inside the car so I think it will only need a motor or motor repairs and will not be a total loss. So my questions are:

Does anybody know of a good low mileage 2010-2012 LS460 complete motor?

Does anybody know what the difference is between the 2007-2009 and the 2010-2012 motor
as it has a different part number?

I know i can probably just get a new long block from Lexus for about $20k but I want to try to fix it as easily and economically as possible.

Thanks for your help.

Why not use your insurance?

Just one question.......why was your wife trying to got through wheel-deep water? Was there a reason she simply couldn't ride it out with the engine off until the water receded a little.....or was it a life-threatening situation? The hazards (and potential hazards) of trying to drive through deep water are well-documented....and well-publicized. I just did a recent CL thread on them myself.

She was on her way back to California that morning and was proceeding on a back road in a line of other cars at the time. She didn't know any better and was afraid to stop.....just followed along in the conga line to disaster with a BMW 3 series and Toyota Sienna...both of which ended up with the same issues.

I want to fix the car....don't want it totaled out. My insurance will pay for it under comp coverage.

The only difference I am aware of is the newer engines are direct injection while the earlier engines are port injection. I think the spark plug change interval for the newer engines is 60,000 miles versus 120,000 for the earlier engines.

There may be other differences.
