Oil vapor/smell under load

[64T-bolt]

I had my car out today and it was running well. whenever i goose it a bit and it's under load, i smell oil in the cockpit. no smoke, pulls hard, just a hint of oil smell inside.

only thing that i have done since before it started was put a new coupler "spider" in my kenne bell. .

Did you reconnect all of your breather hoses or PCV line?

If you're running just breathers on your valve covers, you may have excessive blow-by gases especially under boost.

still has stock PCV lines/check valve.
