Well I took my car in to another shop and had a leak-down test performed. Here are the results:

#1: 8%
#2: 20%
#3: 24%
#4: 18%
#5: 18%

These results are not too bad for a car w/ 160K--the first shop (an independent Volvo mechanic in Chico, CA) had said that my #4 and #5 were 89% and 65%, which had me freaked. Their claim was that this pressure was too high for any PCV system to bear; therefore they were not willing to guarantee the RMS they had just replaced. This seemed like a way to opt out of standing behind the job. And the car recently passed smog with no problems, so I was confused as to how I'd get these high values.

I am having the new guy (a Euro/Porsche mechanic) replace the whole PCV system + new intake manifold gasket. When all is said and done, I'll have a new RMS and PCV system and hopefully no more headaches...
