...cars need the cat for the MOT?

 

1993/4 for petrol iirc.... diesels dont

 

i think 92/J reg is the last year you cannot have one, for imports your allowed up until 1995

 

...so we have a difference of opinion?...i had an inkling it was 94

 

No car needs a cat to pass an MOT

All they need to do is pass the relevant emmisions test

 

Edit. There you go ^

 

...so a k reg sapphire will be 3.5% ?

 

my k reg saff didnt have a cat and i never had any problems getting it through an MOT

 

After sept 1992 iirc all uk petrol cars had to be fitted with a cat. Doesn't mean it needs one though, but it does have to pass the 'cat standard'.

 

As above, exactly correct as far as I'm concerned.

 

Although you don't technically need a cat to pass an MOT, if you are pulled in by VOSA for one of their roadside stops, they will do you if you've removed the cat! Happened to a friend of mine. Not worth the bother IMO.

 

Don't think that's possible???
How you they prove you removed it if you haven't had the car from new?
If the physical presence of a cat is not checked at an MOT then how would it stand up in court? It's perfectly possible for the car to pass it's emissions test without a cat installed.

 

I don't know mate to be honest.

Probably the same way that an old car of mine passed the MOT with tinted windows, yet I got pulled in for a VOSA check and got done for it.

 

Its 1992 as said above as many moons ago i had a 92 reg xr4x4 sierra and it had no cat and just got through because of the month it was built or registered.Not sure which off hand now.

 

Phil was it not only the green top cossies that came with the lambda sensor ect? if yours is a red top it should be ok? i could be totally wrong but that was my understanding

 

I'm sure its 1st August 1992, mine is a greentop and I've fallen foul of this a few times so I'm changing back to closed loop to help things out in that dept.

 

Mine too,good old MSD closed loop.

 

+1 if you can get it through the emmisions with out it ,it dont need one

 

mine wasnt on closed loop

 

This car is closed loop so no worries then

 

I do 0.97% CO, 137PPM, on GREYS/T34, with very close on 190,000 miles on bottom end, NO CAT in sight,
NO CLOSED LOOP in sight, but then it is mapped correctly.
tabetha

 

So you would fail the catalyst test. How is that of interest to this topic?

 

Legal limit for a cat-test is 0.3% CO.

 

91/92

 

worst case rebuild it with a pre 1992 block and use the engine age to get round emissions regulations not the cheapest method though
