2uzfe camshaft timing tube (vvti gear) oring

[CruiseLander]

hello 100 series folks. I have acquired a 2006 lexus lx470 with 292K miles recently. I will be changing doing a 90k service and changing the camshaft seal. There is a o ring in the camshaft timing tube (VVTi gear) that can fail and leak. Has anyone on here have experience changing out that oring. People have done it on 1uzfe engines with success it looks like. Any input would be greatly appreciated. I put a link for reference.

So if anyone comes across this issue, I ended up just ordering new cam timing tubes for my LX470. However for my 2005 Lexus LS430 with 250k miles, I ended up changing the oring inside it and so far no leaks. It was a very straight forward and easy procedure. One of the tubes was slightly weeping either from cam seals or the oring but the oring was extremely brittle on both sides for reference. I think I used the oring from this guy. No affliation with the link.
