OP- IMO the Mobil 1 0W40 you mentioned would be a great choice in that engine.
This is the first FB I’ve heard that’s had a dripping problem. Over the years I’ve done 3 of my EJs’ VC & spark plug tube seals but haven’t had any issues with the FA/FBs yet.
Same here. 140k miles on my FB and zero leaks or burns. Even the EJ’s I’ve rocked in the past just had weeps here and there.
Not saying it won’t ever happen, because flukes happen, but now that I’ve switched over to a certain oil, I know that the seals & gaskets have their best shot possible at a long life!It was definitely a rare case it seems. I still have the oil stain on my garage floor to remind me of the whole thing.
The OP mentions JDM engine, although I do not believe the 2015 JDM FB25 is DI either.The 2015 was direct injection? Mine isn’t.
Sorry maybe I mixed it up with my FA20 which is direct injected turbo.The 2015 was direct injection? Mine isn’t.
I am sorry I was mistaken. I assumed F series were all direct injected.The OP mentions JDM engine, although I do not believe the 2015 JDM FB25 is DI either.

Might want to check/change PCV if it's this bad. If it's bad might be pressurizing crankcase and causing these issuesCam carriers and covers on both sides. Passenger side got to the point it was dripping pretty bad. One of the worst ones my dealer had seen. It definitely had plenty of undercoating on that side
