Is there any point notifying dvla of replaced engine?

[SpeedySpeedBoy]

Engine was faulty and just replaced it with another engine from same car. Therefore no increase or decrease in size or performance, it is the same engine.

1. Do I have to inform dvla or not?
2. The replacement engine had a low mileage so thats a good thing for future sale, but I don't think theres any way to prove the mileage besides showing the original ebay advert. Can the v5c somehow be changed to reflect the lower mileage which comes with the new engine or not in which case there's probably no point in notifying the dvla?

thanks

If you don't inform DVLA then any diligent future buyer checking the V5 against the numbers on the car may be suspicious .
DVLA will not adjust the recorded mileage on their records .

If your log book shows an engine number, I would tell the DVLA.
If it doesn't I wouldn't tell the DVLA.

You need to tell the DVLA so they can update the engine number.
If you don’t do that firstly you’ll never sell it as no one in the their right mind would buy a car where the VIN and engine numbers don’t match the V5.
Secondly, if you come across a scrupulous plod, the numbers not matching may ring alarm bells.

I've sold cars for a living for the last 6 years or so and never once had anybody even remotely interested in checking if engine numbers match the log book, VIN numbers are another story but still an extremely small percentage of people of people that actually bother to look.

What the worst that can happen if you don't notify them and they find out? Slap on the wrist?

Depends, if you have an accident and kill or seriously hurt someone your car will be inspected and you will then be right in the 5hit.

I can confirm, as a punter I have never looked for an engine number on any car I have ever bought or owned!

For not having the engine that your log book says you have.
Mr insurance company will probably then use this to squirm out of any pay out.

Do people in this thread really think the general public would even think about telling the DVLA if they replaced the engine in their {generic family car}?


Realistically, the only time normal people consider documenting it properly is on a high value performance car.

Can you document some examples please?

Is it a legal requirement to notify DVLA of an engine change?

As long as you’ve got a receipt for buying it I’m pretty sure you are in the clear

sounds like nonsense to me. the only worst thing that can happen is if the new engine happened to be stolen. when you update it you might get a knock on the door.

Quite possibly nonsense and you can take a chance if you wish.
Personally I wouldn't and I would tell the DVLA.
This is what the DVLA say.

Changes you need to update
You must update your V5C if you change any of the following:
colour
engine
cylinder capacity (cc)
fuel type
chassis or bodyshell (replaced or modified)
seating capacity
weight of a large vehicle, eg goods vehicle or campervan

1. Yes
2. No

I’ve changed an engine and notified DVLA. When I used to change BMW block and pistons (at main dealer) we stamped the old engine no on the new block.

I have also changed my car from auto to manual and notified the DVLA.

[buggalugs]

Whenever I’ve tried to look at an engine number the bloody thing has been pretty well hidden I.e. couldn’t see it without taking things off and borderline unreadable anyway on a rusty iron block.

[konark]

But you haven't changed the engine, you've replaced it with an identical one.

Would it count as a change of colour if you had the car resprayed the same colour?

Anyway hands up who's checked their engine number with the one on the V5. Most people wouldn't know where to even look, and on most modern cars it's difficult even to see the engine.

With a different number. The number is on the V5C. Why would you not ensure the V5C had the right number on?

Your car gets nicked. The people who nick it strip it, and scrap the shell. When their workshop's raided, there's an engine sat there. It's out of your car, but your V5C says it isn't...
