Popped oil dipstick weeks after a new breather box 700

I opened my hood after a two-way trip over a mountain at highway speeds(70mph on a 7% grade for 5 miles) and found my dipstick had popped out and sprayed a good amount of oil in my engine bay. I was glad that the fluid that was all over my vacuum booster was oil, not brake fluid.

Anyway, I just replaced my oil trap a few weeks ago, are there any other maintenance issues that make sense as a cause for high crank pressure?
The reason I opened my hood was to pull engine codes, looking for a bad AMM code.
The AMM is bad and it's running a screwey mixture until I can get to the JY tomorrow.
I'll try the oil-fill cap test before I head to the j/y tomorrow.
I switched to full-synthetic oil, have changed the filter once (about 5 weeks ago with the oil trap) but not the oil yet.

Is there a one-way valve that might be bad or installed backwards?

Appreciate any help,
Happy Bricking,
Will
