Lots of advise guys so thanks .

So assuming car can be raised to allow easier access for drilling/cutting new holes for welding thats the safest/probably quickest option.

Didnt really fancy pulling the 2 cats off what with the inevitable issues with bolts shearing and still requiring drilling out anyway .

As with most things DIY its one of access ..and then having the correct tools and the ability to use them properly.

To save me spending ages looking for one, is there a decent picture of a resited sensor?

From one of Marks threads.

I think mine are a little further back, nearer the bend.

[VXL V6]

Should add, I just bought two new sensors and left the old ones in place.

Leaving the existings in place will be my plan as cant see the sense in creating further problems trying to remove those that have been there for years ,and only needing to bung the hole after 

Just need to develop a plan of attack 

Cheers for the picture Nick

Whats the difference between the 2 lambdas listed ..apart from around £45 each

[VXL V6]

Two different types dependant on manual or auto transmission and front or rear fitment, ultimately the only real difference between them all is the length of the cable.

Thanks VXL V6.

So assume longer cable for rear ? and being auto just  1 selection

Or you can buy them without the plugs and reuse the ones on your existing ones - just cut them with a tail and solder and shrink tube them twice to give some heat and moisture protection.

Soldering etc is just another added complication ..want this done with the least amount of agro and effort.

You can buy blanking plugs from the same suppliers as the bosses. Or they're a simple turning job. Either way, it makes for a more professional looking job.

That assumes you can get the old Lambdas out,Nick.

Looking for the simplest method really as cant afford car off the road for too long removing cats etc....time/money and all that malarky

Regarding removing O2 sensors. . . Mine came out no problems. . . A few decent whacks with the hammer on the wrench. Obviously make sure the wrench is properly seated.

Usually the bosses have the blanking plug in them.

A lick of the oxy-acetylene usually shifts stuck fittings easily, lamda sensors included.


I do understand why you wouldn't want to remove the cats; dealing with broken bolts in the mid-pipe joints is easy, but damaging the manifold studs makes a real problem. I only suggested that as I could fit the bosses and move the sensors for you quickly and easily, without having to shift a load of equipment.


Perhaps we should draw a line here, as this thread is making a relatively simple job sound complicated! And I know that am guilty as much as anyone else.
