i have an exhaust leak where the manifold meets the head on the back bank cyl.6. it makes a noise but is there any consiquences to not fixing it ?

thanks

Your going to run rich because air will get in and effect the O2 sensor.

okay ill get around to fixing it...if i keep the car.

thanks

Not to hard to do, as long as the studs don't brake. Lots of PB blaster. Start spraying the studs a week or more before hand.

I might be having the same problem only worse it seems. My engine compartment got all smoky today, and my car is running like CRAP! It happened all of a sudden like going down the highway.
That whole 02 sensor thing might be right up my alley. Its a good thing I have more of the gaskets for the exhaust.
Would this cause a car to seem to be running a cyl short? My car stinks like gas.
Sorry if i took this thread in an unintended direction.
