Re: Oil in the Intake System
Item Subject: Text_1
The discussion of oil in the intake system reminded me of a
question I've been meaning to ask the list. A reputable Audi mechanic
told me that the oil from the PCV gets into the intake and then into
the vacumn system. This oil is what causes failure of the vacumn
solenoids of the AC programmer head. Apparently their was a TSB from
Audi on this and Audi designed a special part to fix the problem but
according to this mechanic Audi solution was so overly complicated
that he developed his own which is to put a small lawn-mower size in
line plastic fuel filter on the main vacumn hose going to the engine.
Then the oil then collects in this filter and the vacumn solenoids are
saved. Anyone BTDT with this problem or a similar solution? I plan on
trying it when I R&R my solenoids soon.
