Hello people,
I am currently in the market for a BRZ. I have been looking around and noticed some cars have black soot in the exhaust and that the oil smells like gasoline. To me, it seems that the car is running rich and that either there is a leaking fuel injector or the piston rings are worn. I just wanted to know if this is normal in boxer engines or if the piston rings are simply worn because the previous owner didn't take care of their car.
Any insight is appreciated
Thanks,
oma
