Well, finally got around to pulling and capping the vacuum block lines one at a time to chase my high BLMs. No changes till I did the PCV... watched as my BLMs slowly dropped from 150 to about 143 then I stopped there, but they may very well have continued! I have the correct AC Delo valve coming in today, and I understand that may help. Going to install it with some silicone around it and the intake grommet and zip ties around all hose ends.
The real question is: Does anybody know what is a "normal" change in BLMs when the PCV is connected? I mean, it's JOB is to pull *some* air in under vacuum, right?
While we're on the subject of BLMs, I do have some exhaust leaks at the turbo flange (which I *will* fix), but isn't that too far past the O2 to make a BLM difference?
Thanks, Jay
