I can "breathe easy" so to speak for another 2 years, my '84 Westy with 2.1 passed Virginia emissions. My numbers are:

When the inspector brought the Vanagon back around to the front of the shop and handed me the keys, he said "No offense, I expected it to fail, just because of the age". I laughed, and said I was confident, but not 100% so. If all goes well, next test will be with the Subie 2.2      Jeff
