Two resources of interest to forum readers:

1) Great article on PCV service: http://www.brakeandfrontend.com/issu...ontentid=93623
-note photos 11 and 12, shows the carbon PCV plugging can extend into pan.
-recommendation to get your pan as clean as photo 13 befriend a repair shop w/ a heated parts washer (citric acid works great). Just got my 06 cleaned for 2 pepperoni pizzas.
-reason I recommend servicing is I was surprised at how brittle the o-rings were at 110k mi

2) Great tech bulletin on Volvo sludge engines: http://www.aera.org/ep/techbulletins...010/TB2538.pdf
- I can not believe anyone would put anything but synthetic oil in their volvo after reading
- gives you background on why PCV plug and impact
-highlights the importance of o-ring service
