O2 sensor location on a 4.0L Manifold?
I'm researching putting the 4.0L head on my 4.2L engine. On the 4.2L, the
O2 sensor is in the exhaust manifold. When I researched the exhaust
manifold for the 4.0L Head I didn't see a location for the O2 sensor.
So my question is, where is the O2 Sensor located on engines with a 4.0L
Head and Exhaust manifold?
If I put a 4.0L head and exhaust manifold on my 4.2L engine, where will the
O2 sensor go?

Re: O2 sensor location on a 4.0L Manifold?
There are two O2 sensors on the exhaust on a 4.0. The first one is on the
down tube after the exhaust manifold. It is easily seen when under the Jeep
behind the driver side front wheel. The second it on the cat converter.

Re: O2 sensor location on a 4.0L Manifold?
So for me to put the 4.0L head on my jeep with EFI I would need both the
4.0L manifold plus a section of exhaust pipe for the O2 sensor.

Re: O2 sensor location on a 4.0L Manifold?
Maybe the newer 4.0L (TJ) has two O2 sensors, but there is only a single O2
sensor on my 92YJ 4.0L on the exhaust pipe before the cat. None on the cat.
