I noticed a little bit of oil in the throttle body. Any suggestions on fixing this?

Pcv?

Is there oil on your air filter?

There wasn't a ton of oil. Maybe a teaspoon. The filter was dry and clean.

The only places oil could get there are from the PCV system. There is the fresh air side that supplies air from the filter box to the front of the valve cover. The other side of the system is where the intake manifold sucks the air from the rear of the valve cover and burns the oil vapors. It must've come from the fitting on the rear of the valve cover.

Blowby will sometimes force the oil into the intake.

So can I pick up a new pcv from autozone?

It's not really a valve, it's just an orifice in the fitting at the rear of the valve cover. You can take it out and be sure it's clear. Be careful, they tend to get brittle with age.

The front one is just straight through with no restriction.

typically a PCV valve has a flapper that closes during high vacuum. That may not be working.
