Can a 172 (lean right side O2 sensor reading) be caused by a leaking exhaust manifold?

And has anyone had an exhaust manifold fixed/replaced and perhaps remember the cost?

If I had the time and a spare vehicle, I'd try it myself but I don't have either so I'm afraid I need to pay someone.

 

I would say yes...never fixed 1...I did replace an O2 sensor

 

i replaced my right side exhaust manifold. it was cracked right in half. 25 bucks for the manifold off a truck at the junkyard, 25 for new manifold to y pipe studs. took it off myself.

 

Through the wheelwell? Any broken studs? Any major PITA hangups?

 

crack in manifold opens up w/heat
flow of exhaust causes pressure drop &
sucks o2 in
sensor reads false o2 as lean
old manifold easy off, brake 7/16 studs o/well
new ex will have
recomend new o2 sensor

 

can anyone decode what he just said?

 

Now that's funny!


I'm guessing it was that the manifold was fairly easy but a bolt or two broke and he'll be getting a new O2 sensor (a recommended addidtion to a new manifold).

 

Have no problem at all.
