@Henstepper Yep it's a tight fit the 2GR given it's a FWD setup, I get it, if it were a Lexus GS it would be a rear wheel drive setup making it much easier for servicing, but hey it's a quality 3.5 V6 & they're a dying breed so be greatful you have one 😉 .
There are many people out there who are fairly unsatisfied with the current trend of gutless tiny turbocharged motors on big heavy cars which clearly aren't up to the task, especially if you load up the vehicle with people & luggage. The Aurion can at least be driven sedately & return good economy with the bonus of lasting several lifetimes if serviced correctly. Not to mention smooth, powerful & quiet.
"Dodgy brother" method can work if done well. I commented in other thread Ash linked to above but essentially clean well & layer hi-temp oil resistant RTV, let dry for a day each layer until you build up a good barrier to prolong it's life. Don't drive it until the job is finished. I used this exact method on my haciroku years ago for a typical systemic assembly line failure with the Subaru motor where almost every FA-20 had the oil leak from the timing cover in exactly the same spot.
A crude repair I cared not because it worked, then Subaru in their infinite wisdom decided all FA-20's of the era should have new valve-springs & so the engine had to come out for a partial teardown which included removing the timing cover 🙄
Oil leaks are annoying if they ever pop up, even small leaks. I profess to being a member of that exact "dodgy brother" remedy & it works if done properly. Ideally make sure no oil is directly above where leak coming from otherwise drain it, super clean & degrease the area with wax & grease remover and/or brake cleaner then coat well with hi-temp oil resistant RTV & let dry for a day or two, refill (if drained) & drive. If you apply RTV in layers to build up a good barrier I think will prolong its life ;)
'96 is the OBD2 changeover year for the US market, not Australia. OBD2 didn't become a thing in Corollas here until the mid-late 00s (the 7th and 8th gens still used OBD1 and ye-olde-paperclip scan tool,, the 9th gen ZZE is kinda-sorta OBD2 depending on year/model and Toyota did have some proprietary code despite using the standard OBD2 interface)
