I did my own valve seal repair since my dealer was a pain in the arse along with my 3rd party warranty. I fought up to VP of the warranty company and stated they are not willing to cover anything until my engine blows up.....and I heard they do very sketchy things to remedy the issue.
So....at 100k miles I performed the seals replacement along with associated gaskets and other things.
I'm at 118, near 119k miles which means about 1-2k miles away from my next oil change ( interval 5-6k miles)
No oil loss reported. Gauge said full. 9 quarts goes in, 8.5 or so comes back out.
Good luck, hope it does the same with you
