Hi, I joined this forum to try to help some guys out that might be plagued with the same issues I have.
Anyone who has a 3.7 with the BBK longtube headers knows that it eats O2 sensors left and right. I have personally gone through 4 sets in a matter of 50k miles. Ive heard tons of theories of why it might be eating them. Resistance issues, location, bad extensions. Whatever. No one has proven anything yet though that I'm aware of.
Here's my theory. Moisture. I believe that these sensors are too far down and its allowing the sensor to bath in moisture. Over time why would this not cause issues? Every time I change my o2s they have droplets of water on them. I removed my x pipe and they were soaked.Now if they were moved way up closer to the block like the stock location then these moisture issues will no longer be of concern. Either way. I believe I have come up with the solution to this issue. Only time and miles will tell though. So far so good.
What I did was grabbed a couple of old oxygen sensors. Mocked up where I wanted them with paint pen. And moved them back up to the stock location. Now we're only monitoring one cylinder on each bank this way but it eliminates moisture issues and eliminates the need for the BBK extensions as well. Two birds one stone. Why do I have faith in it only monitoring one cylinder per bank? I got this idea from borla. I did some research on borla and mimicked their design. If borla does it it can't be wrong in my opinion. If anyone here would like step by step directions on what I did speak up I'll post them.
