*the bunge located above the throttle body is restricted with brown crud.
*inside of intake manifold shows signs of oil contamination. While I can still see some of the green coating, oil is in there.

Welcome to the Xoutpost community! And congratulations on purchasing an excellent piece of engineering.
Notes on your findings.
1. Oil in the throttle body and intake manifold indicates that it’s sucking oil out of the engine. There no other route for oil to enter the intake manifold. And the only exit route is into the cylinder and out the tail pipe as smoke.
2. External oil leaks are messy, but don’t harm the engine. As long as you keep the oil level up. So, if you’re looking to minimize cost, you can wait. Just park over cardboard.
