I got it from NAPA. How can I tell if it's junk? I just want to know the symtoms for my own edification.

 

Front O2 Sensor and gaskets.

 

KSteng89,

Is the front O2 sensor the item directly to the right of the thermostat as you look at the engine?

 

Excessive Oil consumption. Aftermarket valves don't have as tight of control on flow rates.... so, they tend to suck oil too.

Sensors on the manifold by the thermo housing are engine coolant temp sensors. O2 sensors are in the exhaust. Pre-cat is the one right where the two down pipes come together at the cat. (unless you have california emissions.....)

 

Thanks brother. I appreciate all the advice/inputs. I already replaced the exhaust O2 sensors last month so at least that's done. I will head to the dealer on Monday to get the PVC.

 

While you have the kegger out you can do the kegger mod and cut them runners down.
