Just wondering if they can "start" to go bad and affect mileage/performance without causing a code. I have a 95 Disco with 83K on it and some time this weekend......

Yes, especially with OBDI :). But don't worry, contrary to what they tell you, O2 sensors can and usually do last longer than the 82,500-mile interval they suggest (and since the ones on the Disco are heated, they typically last well past 100,000 miles. With age, O2 sensors lose their effectiveness. But when O2 sensors fail, they fail; it's not really gradual. You would be able to notice a significant decrease in gas mileage.

Stupid question...but...

What happens if they go, and you don't replace them? I think this is what happened on my '96 Disco-84,500 mi on it, a couple of thousand miles ago. How expensive is it to replace them, and is it an easy DiY job? I turn into Corky (oblah-dee, oblah-dah) when it comes to all things automotive.

Cost depends on exactly which you need. Nathan has the best prices on genuine ones: http://www.discountrovers.com

There's at least 2 other threads right now that talks about changing them: unscrew them and unplug, screw in the new ones and plug them up.

If you don't, then you get REALLY crappy gas mileage, bad emmissions, poor running, etc. etc.

Well if they go, you will normally start to experience hesitation and shutoffs at stop lights etc....It's a real annoyance. Yes you can change them yourself....just head down to your tool store and purchase a crowsfoot- I still forget what size, but its a MM- Do it when your truck is cool.

Leslie,

I tried the link you posted and I get a Page Not Found message.

Any other way to get a hold of Nathan?

You're using Netscape..... #@$^%&.... :)

I use Netscape too....

Try the link in IE....

That's the only reason I use IE, is to hit his site (and EE's BBS)....

Nathan's website has his phone numbers, and his email ([email protected]).

The sensors are 17mm. Yes, a crow's foot works well on some of them, while Snap-On sells a deep well 1/2" drive socket with a slice out of one side for the wires.

Replacing the sensors is no great shakes, but the connectors were placed by a true sadist. To connect one, I had to enlist the help of another person to hold one of the connectors from the other side.

Cheers

LOL....

Didn't we go through that before?? They don't have ones spec'd out for a Rover... the generics are "kinda" close, but not exactly right.

I'm all for buying something from elsewhere when it's a better product, or at least the genuine for less.... This'n isn't genuine, and it's not better.... Cheaper, yeah, and it may function fine... but, w/ how picky the Rover 4.0 can be already, I'm not gonna push my luck on it....

IMHO, FWIW.....

Yes they do - same spec as stock - heated 4 wire. Equivalent to OEM number

And most of the stuff Nathan sells isn't genuine Land Rover parts either. It's OEM type of stuff. That's why it's so much cheaper.

OEM vs.Land Rover.

Just because it doesn't come in a box that says Land Rover does not mean it wasn't made in the same factory that made the part that is on your truck.

The factory where I work makes parts for a company I won't name... Their parts go out in boxes with their name on it!

We make service parts for many other companies I hesitate to name. Their parts sometimes go out in boxes with the company name, sometimes with our company name.

Exactly, Paul.


I couldn't get them to cross over the number to the "right" one, said that I'd have to use the generic. FWIW....

Paul,

"Just because it doesn't come in a box that says Land Rover does not mean it wasn't made in the same factory that made the part that is on your truck."

This is undeniably true. But the converse is equally true. Just because a part is labeled "OEM" does not mean it is identical to the corresponding Genuine Land Rover part.

I see lots of OEM parts all the time, including some sold by Nathan, and they are not always an exact match for the Genuine Land Rover parts. That does not mean these parts are crappy or don't fit or don't work or whatever as I have no idea. I'm just saying the parts weren't identical.

Unfortunately for the '95s, the O2 sensors were made by Lucas (which later became Lucas Varity, then was acquired by TRW Automotive, but now most "Lucas" parts are made by Sagem, still under the Lucas name) so Bosch does not make a replacement sensor, as they do for '96s and newer (when Bosch was the OEM supplier to Lucas for O2 sensors), in which case you could walk into AutoZone and buy some for an acceptable price :)
