Re: Dead air flow sensor ..

    I remember the original thread on this subject. It is possible for a
motor with a bad PCV solenoid or turbo oil seals to introduce a higher than
normal quantity of oil into the intake tract. The bypass valve then routes a
pressure pulse back toward both the inlet side of the turbo and back at the
air filter. Paul Krummins car sounds like it has severe flatulance between
gears due to this pulse going unmuffled with a K&N cone filter. That same
pulse could carry plenty of oil back upstream and into the MAF.

>Brett, I've never seen this, nor heard of this happening on any other cars
than Brandon's car.  There's no oil blowback that I can think of that would
affect the sensor, since you've have to have air moving out of the engine to
the air filter box.  I think his car injested some oil into his air intake
from somewhere...
