How does un burnt fuel on the back of a car have anything to do with a blown head gasket??

i may mean that theres a lot of smokg and all cars get black shit on the back compared to the front. My jetta always got shit on the back b/c it was smoggy out and dirt in the air would not be blown off of the back due to wind force...if anyone understands it..

if its oil, its either your valve seals or piston rings. if its rich... try changing spark plugs/plug wires and if that doesn't work check the timing.

The A/F gauge reads lean so I guess that would mean oil.
