Guys and Gals,
Check you PCV Valve/Grommet and replace it often. Cheap and easy when you catch it early. I pushed mine just a little bit long and it came out in two pieces, nightmare if it's brittle....I cut mine on the two sides all the way down before taking it out, stuffed the center with tape, and had a vaccum handy if it had gotten dicey. I'm coming up on 330k and was doing some deep cleaning this weekend and decided to do that and I'm so glad I did. $0.02
