Symptoms of a Stuck PCV

  1. Engine misfires at idle.
  2. Lean air-fuel mixture.
  3. Presence of engine oil in PCV valve or hose.
  4. Increased oil consumption.
  5. Hard engine start.
  6. Rough engine idle.

Subsequently, question is, why does AFM cause oil consumption? The AFM excessive oil consumption problem usually crops up on vehicles that go on long highway drives. These kinds of trips don't put much stress on the engine, so the AFM system deactivates pistons. A shield was added that keeps the oil from being pushed out and sludging up the pistons.
