My Anti seize pre-dates O2 sensors.
Any suggestions on O2 safe anti seize ?

Sensor failures

Normally, the lifetime of an unheated sensor is about 30,000 to 50,000 miles (50,000 to 80,000 km). Heated sensor lifetime is typically 100,000 miles (160,000 km). Failure of an unheated sensor is usually caused by the buildup of soot on the ceramic element, which lengthens its response time and may cause total loss of ability to sense oxygen. For heated sensors, normal deposits are burned off during operation and failure occurs due to catalyst depletion, similar to the reason a battery stops producing current. The probe then tends to report lean mixture, the ECU enriches the mixture, the exhaust gets rich with carbon monoxide and hydrocarbons, and the mileage worsens.

Leaded gasoline contaminates the oxygen sensors and catalytic converters. Most oxygen sensors are rated for some service life in the presence of leaded gasoline but sensor life will be shortened to as little as 15,000 miles depending on the lead concentration. Lead-damaged sensors typically have their tips discolored light rusty.

Another common cause of premature failure of lambda probes is contamination of fuel with silicones (used in some sealings and greases) or silicates (used as corrosion inhibitors in some antifreezes). In this case, the deposits on the sensor are colored between shiny white and grainy light gray.

Leaks of oil into the engine may cover the probe tip with an oily black deposit, with associated loss of response.

An overly rich mixture causes buildup of black powdery deposit on the probe. This may be caused by failure of the probe itself, or by a problem elsewhere in the fuel rationing system.

Applying an external voltage to the zirconia sensors, e.g. by checking them with some types of ohmmeter, may damage them.

Symptoms of a failing oxygen sensor includes:

* Sensor Light on dash indicates problem
* Increased tailpipe emissions
* Increased fuel consumption
* Hesitation on acceleration
* Stalling
* Rough idling

Thanks, hope mine comes with some as well.

And did anyone ever come up with a way to get that B2S1 Out ?

Yup mine too.


My CEL keeps going back off and then 1 day later back on so I'm less motivated every day to fix it.

Just looked under the hood. You do mean B2S1, correct? The one above the cat on the rear bank facing the firewall?

Doesn't look like it'd be that hard to change. What's the problem?

Right, but what's the problem?

Can't get your wrench on it? Can't get leverage on the wrench? Thing is stuck? Are you using an O2 socket? Did you remove the intake tube?

Gimme a hint!

I tried to get them undone with a wrench, gave up and got a O2 socket.
so they are all out except this one, cant get to it to get the leverage on the breaker 3/4 inch bar. now the exhaust was loose, which made it more difficult. I may try again once the gearbox it back on and the exhaust tightened up. yes the Air pipe is out. couldn't get the manifold out the top or bottom, engine is dropped and tilted. I didn't want to mussel it and damage something.

Maybe this is the problem. I haven't replaced it, but from looking at it, it didn't seem like it would be such a pain.

I'll take a pic in the morning and you can make the call.

Hope this helps. Look like easier access than what you're dealing with?

Went with the Denso and found a 10% off coupon

I went to the Denso site or so I thought, and when I purchased was diverted to sparkplugs.com

I purchased the generic, same for all four, and comes with anti-seize, crimp on joints and shrink wrap, genuine Denso. about $45 each for 2 shipped, yes I used a coupon for 10% that offset the shipping. Also check amazon, as they were about the same once you have the part number.

DEN234-4209

On the Box 234-4209


Spark plug, Spark plug wire, spark plug gap, spark plug cross reference and ignition wires at Sparkplugs.com

I just did B1S2 on my car. Here are some tips if you buy the universal sensor (IanH, beware of deja vu):

This takes about 10 minutes, and will save you about $50 vs. a direct fit.

Lay out the OG and replacement sensors side-side. Fortunately, there's a piece of plastic loom right where your splice will be. Peel off the tape on the plastic loom, and push back and tape the rubber loom to expose the wires. Stagger your splices so that you don't get a big lump in the line and that the connectors don't rub against each other and possibly wear down the shrink wrap and short each other due to all the vibration. The butt connectors that come w/ the Denso sensors are really nice, and I'd like to get some for other projects.


Just looked at that Amazon link. Looks like they went up $5 since when I bought one a couple weeks ago.
