It is possible then has come from a stolen recovered car... often the numbers are removed by the theifs.
If you had a reciept for the engine then this would be ok... one of my old Land Rovers just had 'unrecorded' for the engine number - but at least you could prove where the engine was from.
In theory... the engine is still a 2.5 Td so still matches the V5...
You could get hold of another 300Tdi short engine... say second hand, which will then have a engine number.
Or buy a complete engine and sell yours for bits (I might be interested in some of it
) again means you would have an legit engine number.
If it's running a 300tdi... then in theory it will have a R380 gearbox too... instead of the LT77.. has this got numbers on it??
What chassis is it on... a 300Tdi one or the original one??
What rear axle?? - is it a disc or drum braked??
What front axle?? 10 or 24 spline??
- just wondering how many other parts are 300Tdi spec??
