My bad - Don't worry about your oil lines.
You helped me by posting your photos.
I never installed this kind of adapter plate, but looking at the photo, it looks like you used enough sealant, but may have torqued it tight before it dried.
I would go with the most durable high temp gasket sealant, apply just enough but not too much to both surfaces, let dry until it just stops sticking to the finger and then bolt it down and let dry over night at least before starting the engine.
Never ever get discouraged.
Thanks to this site we never ever end up on a dead end street, ditching the truck...
Your truck will run as reliable as anything you can imagine.
And when it does you will not have the words how that feels.
I love to open my hood only for cleaning and enjoyment or that bi-annual oil change.
Just did my cold-season change this afternoon....
