My 2012 RX350 with 79,441 miles had the timing cover leaking oil. It was resealed by the dealer in December 2021.
Then in December 2022 it looked like it was leaking again, but after the dealer did diagnostics, they said the timing
cover reseal was good and the oil was coming from a high pressure oil line that needed a small gasket replaced.
The original job cost me $1,220 (it was subsidized by the factory). My car now has 84,552 miles 1 year later..
They now want to charge me $494 to replace the gasket, so I called Lexus again and am waiting to hear back from
a case manager who has been assigned my case.
My concern is that the timing seal is still leaking and the high pressure oil line is NOT the cause.
There is an excellent video on YouTube by the "Car Care Nut" who was a master mechanic at a Toyota dealer where
he reseals a timing cover leak on a 2015 RX350. He has done this repair hundreds of times and he has never seen the
leak coming from the banjo bolt. He says it always is in the spot where the cylinder head meets the cylinder block in back
of the timing cover. Since the oil line is close to the banjo bolt I am skeptical of the dealer's diagnosis.
Any advice and comments are greatly appreciated.

Dealer has you over a barrel unless you get them to fix the oil line leak, according to them. If it still leaks then it will be much harder for them to not take responsibility. You know by watching CCN's vid it is easy to screw up the timing cover repair.

You can always remove the passenger side front tire and look at the leak area to see for yourself what is leaking. Or take it to an independent shop for a second opinion.
Those banjo bolts do sometimes leak and after 84,000 miles I would not be surprised at anything that failed on a car.
