Oil Leak

I've been having a rough time with this build. Nevertheless I love the car and smiles I get but now I have another issue.
Took it for an oil change at a local performance shop and tech noticed I was leaking oil. Doesn't pool on the floor, no powerless nor check engine light.
He stated that the piece I circled which sits on the intake manifold and holds the engine cover was loose/almost broken. Took it to my local dealership and now waiting for a response :

Saw this recently on the Supra forum. Seems to be a potential design flaw / weak point which is damaged by the engine cover removal.

Looks like the same issue. Thanks for sharing!
Hoping it's something pretty minor and nothing internally wrong

Yep. The picture you shared looks like the valve cover rather than the intake manifold. Do you know if the broken mount is on the rear left side of the engine (when standing in front of the car facing the engine)?

Assuming I'm looking at the engine bay it's on the far left

Yep, valve cover and same spot as the Supra example. I’d hope warranty covers it!

Dealership called me, turned out to be the valve cover. It's going to be replaced and under warranty!

Just picked up my car from dealership, found oil around intake and turbo after further inspection dealer came to the conclusion of valve cover as well. 45.5k miles so thankfully it got done before warranty expired. Not sure what would cause such an early failure.
