While You Are There - Valley Plate Leak

[ExpeditionMan]

All,

Unfortunately, my 2013 LX570 w/ 168k miles has developed the valley plate coolant leak. Are there any "while you're there" items i should consider during the repair?

All the following were replaced with OEM during my cooling system overhaul ~40k miles ago:
-Radiator
-Water pump
-Hoses
--upper radiator
--lower radiator
--water bypass (thermostat)
-Thermostat w/ housing
-PCV
-Throttle body gasket
-Fan clutch bracket
-Fan clutch

I was at similar mileage when I did mine, and most every vacuum hose up top was cracked and/or dried out - I would plan on replacing them, as well as the foam pieces. If you are considering the SAIS bypass, the access is really easy with the manifold off.
