What Have You Done To Your Cobalt Today?
the o2 housing gasket is re-usable and if the downpipe to catback one is torn just use copper rtv on both sides of the gasket. might as well use some copper on the 02 housing gasket as well
I don't know how to do either of those so yesterday I decided it had been drying for enough time. Put everything back on. Gave some hesitation but then started like a champ! Smelled like beautiful e85! and then the coolant came....lol I guess coolant had gotten into my exhaust and it was burning off. Smelled horrible. I'm just glad my car ran good. Will begin to adjust my tune and finish it tomorrow probably.
