Sounds rich to me how old is your oxy? Burning excess oil can usually be
smelled quite obviously when you are in the back. If it's excess oil getting
through your tail pipe can often have an oily feel but if it's dry and sooty
at the pipe I think you are running rich...

My saab turbo has an oil leak in the turbo and the stench at the tail pipe
is unbelievable.

Just took off my cat to have a look. Not clogged, can see through it, and
the screen is intact, but it's pretty black--as was the tip of the old O2
sensor I took out. Could this be due to excess oil burning through the
combustion chambers (from whatever source)? Or is it just from running rich?
Or?
