Missing engine number

[Axolotl]

My V5C lists the engine number for my 1971 Traveller as H67349, but the plate on the engine itself is missing. The pins are there, but no plate.

The plate on the bulkhead just has "See engine" in the engine number space.

Can anyone advise on the following questions?

1) Should I be bothered?

2) Is H67349 a valid 1098cc engine number anyway?

3) Is there any way of obtaining a valid engine number (from the chassis number, for instance?) and plate to replace the missing one? (I am assuming the only place the engine number would be is at the front right at the top of the block (looking from the drivers seat), behind the water pump.)

4) Can I get the DVLA to update the V5C to show "unknown" or "no engine number"?

Issn't H the code for 1098ccm engine??

[JimK]

H is for High compression.
The number would have been something like
10MA for 1000-1099cc, Morris.
Letter for ancillaries like gearbox.
H for high compression and the number.

Travellers engine number is 12CE-Da-H16269.

You could wirk out what the various type information should be, but I don't think you can find out what the engine's production number was (if 67349 is wrong).

Ah, just noticed our V5 says 1098. Might have to change that.

but the plate on the engine itself is missing. The pins are there, but no plate.

They are often missing if the block has been skimmed and the later ID plates do just say see engine, nothing to woory about unless you are entering concours.

Can I get the DVLA to update the V5C to show "unknown" or "no engine number"?

I wouldnt do that as they may think there is someting iffy going on.

Dont worry about it. As long as the Chassis number is correct it ususally OK. as said yes H is for a high compression enghine. 10mauh then number is an engine. In 1996/70 this changes to 10v then the number no difference in engine just numbering.

1) Should I be bothered?

Only if you lost the plate yourself... ;-)
I had a low compression block machined and I rebuilt it with low compression pistons as I wanted to refit it to the pickup that it came from - I was a tad upset when the engine machinist didn't rivet the plate back on as per agreement (it got lost )

However it made no difference at all to me, but whoever is now running that engine (probably in a Saloon) will be unaware that it is a low compression engine.

The only time that the engine number plate 'rivets' are removed normally
is if the owner prises them out prior to have the engine overhauled. The machine shops just shear them off in order to have a flat surface for the
equipment they use. If your 'rivets' are in place then someone has deliberately removed the aluminium engine number plate. You could pin it
down further by looking for a plate with '1100' on it beneath the exhaust manifold close to the front engine mount. You could also check if the cylinder
head casting is stamped 12G202 when you remove the rocker cover. From
March 1969 the 10MA-U-H engine number prefix changed to 10V-189-H or L
OR 10V-190---H or L......this was from car number 1248582 so your chassis
number would confirm the correct year. (the numbers only of your chassis number are stamped on the bulkhead just to the right of where the bonnet
opening rod emerges through the bulkhead).

I wonder how many people have used the correct prefixes but made up the last 5 digits?

You can check the engine number by ordering the Heritage Trust Certificate.

That is the way I know I have matching numbers on my MM

(engine number USHM2 61919) I am sad, I know it by heart

[Axolotl]

What is a Heritage Trust certificate, and how do I get one?

[Welung666]

Take a look here and it gives you prices and info on the Certificate scheme

[Axolotl]

Thanks all. I have sent off for the Heritage Certificate.

In the mean time, I have found the tag with "1100" on it, but can't find a chassis number stamped into the bulkhead. Just the alloy plate with the full MAW number.

the numbers only of your chassis number are stamped on the bulkhead just to the right of where the bonnet
opening rod emerges through the bulkhead

Have you got a photo that shows where I should be looking? All I seem to have round the bonnet opening rod are wiring loom and plain painted metal.

There's a post on this thread that shows the location of the chassis number. Mine was hidden under surface rust caused by a previous owner scraping the paint off to see the number better.

[Willie]

The chassis numbers can clearly be seen to the right of the bonnet opening
rod.
