[DML] Re: Won't start cold

[kjc <ckevinj@xxxxxxxxx>]

i'm going to hijaak this thread and ask an oddball question.
could the vacuum lines introduce exhaust odor to the cabin? I know
that in theory this shouldn't happen since the vacuum lines should be
the absence of air but I have to wonder.
I still come out smelling like car exhaust after a drive, always have.
 i've done exhaust gaskets twice (second time with dmch perf setup),
gone around and sealed all wire pass throughs except the large
collection  behind passenger, and even in battery and locked
compartment. the only bits left to do are the rear glass seals, the
said wire bits not done, and lift center console and check all that.
perhaps now I just need to have the carpets and stuff cleaned from
pervious years collection of smells.
opinions?
