When the filter fills to capacity, then bad things like this can happen.
1. Engine is extremely clean, the last 8 or so oil changes have been with Quaker State Ultimate Durability or Pennzoil Platinum, never over 10K. Before that the car has lived almost its entire life with Syntec or M1 on 5K OCI\FCI. Top Tier gas 95% of the time. Also I had the valve cover off a couple dozen miles ago and it was CLEAN.
2. State of tune is excellent. New plugs and O2 sensor about 9 months ago just because.
3. 2.2L EcoTec uses a fixed orifice breather, I doubt it is plugged because the car uses next to no oil (maybe a quart in 10K miles).
A QUART in 10K is "next to no" oil?
