Change of cylinder capacity on v5, engine number required??

[t25 sam]

I have just converted to 1y and was wondering if its a requirement to fill in the engine number section in the logbook?? or if there are any benefits to adding it, other than tracing the engine if stolen??
Also does it change the amount of tax i will have to pay very shortly?

I'm just wondering why on earth you wouldn't bother...? I doubt very much anybody's ever been tugged for not having the right engine number on the paperwork, but given that our vans can and do go walkabout, it seems a no-brainer.

Also does it change the amount of tax i will have to pay very shortly?

For cars & light commercials new between 1973 and 2001, there's only a breakpoint at 1550cc, so no.

thanks for the reply,
to be honest i'm not worried about the "getting tugged side of it" its simply a case of i suppose lazyness on my part, finding the number on an oil saturated engine(as i was in a rush to get it in so i didnt give it a thorough clean down and was under orders not to cover the compound i did the conversion in with oil), to be fair, yes, it may seem a stupid question, i just wanted to see what peoples opinions where on the matter or if simply chucking 1900 in the cc part of the v5 was enough, thats all

And on the taxation side of things is the tax we pay the highest possible rate for this particular vehicle then? would it not go up in accordance with my cc's

Quick google says "1896cc".

Yep.

Pre '73 - free tax.
73-01 - 1549cc or below, 1550cc or above
01 on - CO2 emissions based.

Just posted mine off - I've just changed to a 1Y, I put the engine No. and cc. I made sure I read it whilst preparing it. Put any old No. in in the form 1Y 705xxx (six digits) (you can always say that you misread it due to corrosion! )

Checked last night and it was unreadable, corrosion being the suspect!

My V5 just states "Not Known" for the engine number so I wouldn't worry about it. Got a letter from the DVLA a couple of years ago because the VIN recorded on the MOT cert did not match that on the V5 which had an extra leading zero in. They sorted a new V5 with the correct VIN after I told them the one recorded at the MOT matched the plate. If the engine number was important to them then I would have thought they would have picked up on that at the same time.

This van was imported in 1995 before they took data verification seriously. Nowadays they ask for evidence of the change such as a letter from a garage that changed the engine or may get you to pay for an inspection. See here for more info https://www.gov.uk/change-vehicle-detai ... ce-to-give


With the old system it was just a case of returning the V5 with the data you wanted changed filled in and they would do it no questions asked.

Yep, ours did when we first registered it - I needed to get the paperwork in, but couldn't find the engine number for love nor money. The German logbook didn't quote it. So... blank. And it came back... blank.

Still is the case. I sent our V5C back a couple of months back, for the engine number (located under a good wodge of baked-on gunk) to be added and an amendment to the GVW. The German paperwork said 2550kg, so the V5C came back with 2550kg. The VIN plate says 2450kg - whilst ours is petrol, so currently London LEZ-exempt, I thought 2.5t a sensible barrier to be under for so little an actual difference. It came back in short order with both changes incorporated and no problem.

Mine has just been bounced back to me, they want some evidence!!! Tossers! They also want the original document for evidence purposes so a copy of the one that I got for the insurance co. isn't good enough for them. I made a legal declaration to them and they then disbelieve me. Rant rant.

Oh no iv got some fun to come then, whats the deal if the v5 isn't changed to the current engine capacity tthen? Is your insurance mot tax still valid? it seems stupid to ask but you know what there like!!! Also sorry to ask but what do you mean by evidence? doner car v5? something like that?

[Oldiebut goodie]

Check out the link pirate-pete gave above, I have sent the letter with all the guff on back to them as they asked for it to be returned. My insurance company were happy with it after my local garage gave them a letter to say it was satisfactory in their view.

[t25 sam]

My insurance didnt mention a thing about it getting passed of etc, ten minutes on the phone, told them it was diy and told them the donor van reg and it was all sorted, with no charge!

Went into Northampton DVLA last week and changed mine , i had a letter from Richard to state change and that included the engine number .. Guy on the desk specifically asked for it as well. Regarding insurance , i'm with Adrian flux and just phoned them up today and told them i had upgraded the engine to a 2.5 petrol from a 1.6td and thats all they needed to know £0 increase as well so proper chuffed.

[Oldiebut goodie]

Mine turned up today duly changed - they accepted a copy of the letter from the garage with the engine number on!
Insurance was £0 extra also.

Iv not bothered yet, tried contacting the guy i bought the engine of but i presume hes now scrapped and hasn't got the v5 anymore, iv told my insurance and i also had no rise in premium, bless ya aviva!!
