RE: burning smell on decel.

Keith, you lost me on that "sealess rear crank opening".  Would you please
explain that.

I had problems with my exhaust coming back into the cabin when I originally
my stinger exhaust pointing straight back.  The air flow is rather turbulent
and, from my observations in using the manually operated WindTunnel 55 test
equipment (drive down the Interstate at 55 mph and see what happens :) , a
amount of air travels up from the underside of the vehicle and curls up,
mostly up to the license plate and lower window area.  Well, more so when
DON'T have a lower apron!  So, if the exhaust or any other fumes coming from
engine enter into this airstream it's pretty easy for it to seep into the
area thru poor seals.  Make sure all seals are whole (not "holie" :) and
the exhaust pointing to the outside.

I'm willing to venture a guess that if the foam in the D pillars (the
pillars that have the vents in them) has rotted away that the smell may
noticeable.  The foam keeps water from entering the cabin at high speeds
(personal experience speaking here) and probably acts as an air diffuser,
keeping sudden pressure changes from occurring.  How you replace this I do

Why is this smell during deceleration only?  Probably a sudden rich
when letting off the accelerator pedal?  Beats me.
