Replacement Engine and Emissions
Discussion
Hi everyone, I would be grateful for any advice or experience on this issue please. This is my first post, and I have tried to see if this question has been asked before. So here goes .....
I am replacing the engine in my trusty 1988 Land Rover 90 because its current 300 tdi is now very tired (it's not the original engine in the vehicle). I am going to fit a BMW M57 engine, which should give better mpg, more towing ability and less smoke .....
With this in mind, is it the engine or the vehicle which has to comply with the prevailing emissions regulations at MOT time ?
I have almost convinced myself that it would be the vehicle, but any advice would be welcome.
One reason for asking it that I would like to remove the exhaust gas recirculation from the M57 because it is a can of worms, and I'm sure the Landy would still be much lower emitting than it currently is. But I do not want to junk the EGR if it is mandatory (I understand that it is not legal to remove EGR if the car had it fitted originally, which of course the Landy didn't).
Many thanks !

Tricky one this, because it's not specifically a situation in the MOT manual:
manual said:
Vehicles fitted with a different engine:
- If a vehicle first used before 1 September 2002 is fitted with an engine that’s older than the vehicle, you must test it to the standards applicable for the engine. The vehicle presenter must have proof of the age of the engine.
- If a vehicle first used on or after 1 September 2002 is fitted with a different engine, you must test it to the standards for the age of the vehicle.
- If an engine has been modified in any way, it still must meet the exhaust opacity requirements according to the age of the vehicle.

Looks simple enough.
The M57 production start date is 1998 so it's later than your vehicle and your 1988 Land Rover's emissions will be tested according to the age of the vehicle.
For yours that's a smoke opacity test:
"Test procedure - vehicles manufactured in or after 1980
Vehicles manufactured in or after 1980 must be tested for exhaust smoke using an approved diesel smoke meter. Make sure you follow the smoke meter manufacturer’s instructions.
When testing automatic transmission, you might want to check the vehicle manufacturer’s instructions so that you do not overheat the transmission system. Avoid unnecessary engine acceleration or prolonged high revving of the engine.
Before the test, check the maximum smoke level limit for the vehicle and enter the required details into the diesel smoke meter.
The maximum smoke level limit will be the level displayed on the manufacturer’s plate; or where there is no manufacturer’s plate information:
For vehicles first used before 1 July 2008, the maximum level is:
2.5m-1 for a non-turbocharged engine
3.0m-1 for a turbocharged engine"
