Thread: Running in new D4 motor

I can't find any date tags anywhere in the engine. The engine number is stamped on the cam cover with no other info.
It seems the engine supplied was a ' stripped motor' it did not include turbo, injectors, wiring or any other ancillaries. It seems this was the standard form of replacement motor.
Because the motor was replaced under warranty, I have minimal info from JLR about it apart from engine number. Unlike the vin I can't decifer the the year of manufacture, which would be handy to decide when to replace cam belts etc!

It’s what’s known as a long motor. Includes the heads etc but not the ancillaries. You can assume it’s fresh. Assume the cam belts will be due seven years after its fitting

Yes, it LR 063285 part number, d3 and d4 to 2015, described as stripped motor, I.e long motor. Heaps of references and photos around on interweb. Still, it could of sat on a shelf 3 or 4 years before being installed in my car ?

Even so, it’ll be fine. There’s enough tolerance in them.

Looks like you are out of luck Art. I am sure LR know the build date - pity they did not share with you. I think you have to assume it is identical to your old motor with no changes made.

How much larger is the engine serial number compared to your old motor. Is it 7 digits followed by 306DT?

If these were issued sequentially, then you could assume the factory was producing something like 4-5,000 engines a month to get an estimate on how much later the engine was built compared to your original engine ( I have no idea of the actual number made a year - just guessing).

Would need to compare some serial numbers from different years to see if they are increasing at a consistent rate or if they randomly change from year to year.

The engine number is really long?

On the 2.7 it is 12 numbers/characters. XXXXXXX276DT.

The first 7 numbers look to be the serial number followed then by the engine code (276DT).

Does the 3.0 engine have the same format but instead end in 306DT on both the old and new number?

In regards to running it in - no new engine we have ever had (many work vans over many years, new Land Rovers, etc etc) has ever performed properly until it's had a hard workout. Next time you're towing something and get to a hill, give it the berries. Don't be afraid to let it eat.
