It appears I no longer have vacuum (at least at the manifold on the back of the HVAC control unit in the dash) according to this reference thread
http://naxja.org/forum/showthread.php?t=1143023
Unfortunately, I have been unable to locate the leak so, I need to remove the radio (above the HVAC control) or the entire dash because, the inspection of hoses in the engine compartment did not show me an obvious culprit.
The vacuum reservoir in the front bumper appears fine and so do the rubber lines from/to it. What should vacuum be (at given engine operating conditions be?).
With this in mind, I may have lost a related problem or symptom. That is, my valve cover began being soiled as the breathing lines were clearly being pressurized some time after I purchased the car. Note the engine did not soil the valve cover initially. When I posted this issue on everyone suggested the small valve cover port was blocked yet, this was not (an never has been) the case.
Any ideas regarding the (potentially related) issues?
Has anyone figured out what we can use to replace the fitting in the TB housing the MAP sensor line fits into? The only suggestions I have been able to come up with is a custom machined part.
