Since moving to Haggisland, I have not as yet had the opportunity of meeting a "friendly" MOT man and with ,hopefully, my Chevy K1500 getting ready for one later in the year, I needed a few answers. Now I had heard of a localish MOT chap and went to see him regarding emissions advice and the thirsty 350 sb. The truck has never had a cat since owning it although they did come out with them in the states. What I didn't really get is this MOT chap alluded to if my V5 had no emissions data or figures, I shouldn't be too concerned about failing the test on this as they had no reference point. My V5 has indeed no emissions data. Unfortunately this chap was leaving the area so his "understanding" is sadly of no benefit to me  Now I should make it clear that I am not anti cat but with the price of them and the prohibitive shipping costs from the states, if I can get away without fitting one, I will. Over to the panel........ |

what year and engine is it?
as I doubt these were ever officially sold here there wont be a record on the MOT database, so will go on the nearest applicable basic emissions limit test as detailed in the manual.

I have literally just done the MOT course so I SHOULD be able to answer that but my brain is fried 😂 I will have a look shortly and come back with an answer if you don’t come to the conclusion yourselves with the manual.

Ok, crucial info here is what side of august was it manufactured. Before the 1st August it doesn't require a catalyst test. After it is subject to a slightly easier test as it isn't a passenger car but it will require a cat to be fitted. Bear in mind if it DOES require one fitting cheap high flow sports cats will see it through a test, nowhere does the manual specify it has to be an OE cat or equivalent. As long as a cat is fitted when required and it passes the relevant test that is all it needs.

1992 and not in the emissions database means it should go through at 3.5% CO and 1200ppm Hydro carbons.
Also being a chuffing get big offroader usually means it would be under other petrol engined road vehicles, and may not need BET (basic emissions testing) anyway

I've just spent 4 days looking at the manual so I've kind of had enough of that for a while.  |

Thanks boys for all the info, it's appreciated. For the record it was first registered on 15/9/92. It may be worth presenting it for the MOT and see what happens! The suggestion of a universal type cat may be the best if the tester fails it.

I'm not knowledgable in this area but just a thought, is it an import or a uk car. Does date of registration have the same meaning for an import rather than date of manufacture? Assuming it wasn't new when imported and was registered elsewhere first

Assuming it wasn't new when imported and was registered elsewhere first Wording on the manual is 'first used' However there are some exceptions, but these are documented, like late regiatered 309 Goodwood, they were all pre cat 128 hp engines, but most were regiatered after August 92. But a zx 16v registered in late 92 always ran a cat so needs a cat test as its on the list. |
