997.2 Vacuum Level at oil filler neck

EMC2 · 2016-09-29T01:13:15+0000

Greetings Has anyone had an opportunity to measure the vacuum level at the oil filler neck on a 997.2 3.6l, or have access to what the ideal value should be according to Porsche? I've seen lots on info on the 997.1 engines but there does not seem to be anything on the 997.2. Using a properly calibrated manometer, I got 13.9 in. H2O before an AOS replacement and now have 17 in. H2O after installing a new AOS. Car was running great before and actually feels even better now. As an interesting comparison I get 36 in. H2O on my Panamera GTS. Thanks in advance for any responses
