Ok. I pulled the spark plugs and they looked alright. The electrodes looked like I was running lean and the area near the threads was moderately oil soaked. I also did a compression test. Dry results and wet results:

Cylinder 1: 195, 205 psi
Cylinder 2: 200, 220 psi
Cylinder 3: 205, 215 psi
Cylinder 4: 215, 225 psi

I really can't conclude much from these results. The rings appear to be a little worn but that is to be expected on a 130,000mi motor. They are still holding the pressure fine. The headgasket also appeared to seal fine since all cylinders were pretty equal.

The only thing I can think of that could be causing this is the valve stem seals. Is there a way to test to make sure?

I tried to search for aftermarket dipsticks but can up unsuccessful. I guess I will just let the plastic burn off and live with the smell.
