Reliability of the Ford 2.7 Liter V6 (codename : Lion) diesel engine

Hello
I am in the US. I have a NAS D110 ; been planning on re-powering it with a small diesel.

What are your opinions on the Ford built Duratorq (codename: Lion) V6 diesel 2.7 Liter (TDV6) found on the Discovery before being superseded by the 3.0L V6 ?

Is the 2.7L a reliable engine? Or is it an engine to avoid? Ford here in the US now offers the 3.0L Lion diesel engine on F150 pickups, but a new 3.0L crate engine would be very costly. What I would like to know is if there is a big difference in reliability between the 2.7L Lion / Duratorq diesel and the current 3.0L Lion / Duratorq diesel?

There is a big difference in HP and Torque between the 2.7L and the current 3.0L but what about fuel economy, do the Discoveries with the 2.7L show a noticeable drop in fuel economy compared to the 3.0L ?

They snap cranks, better off with one of following.

TDI300
International 2.8 (based on 300)
TD5

TDI300 easiest
TD5 most power

As you are in the usa I would fit a home grown engine and avoid all the european diesels and their foibles.

The 2.7 has a reputation for breaking crankshafts. It's only a small number, but still a possibility.

Is the USA 3.0L Lion built in the US? If so then it might not suffer the same bad manufacturing process as the French made cranks.

Here, the 3.0L seems just as likely to suffer crank failure, as the 2.7L unit it replaced.

There's a considerable difference in power on the 3.0L over the 2.7L unit, although fuel consumption has remained much the same.

To be fair...... I have a 2009 3.0 TDV6 (196,000mls and counting) and the SDV6 2014 67800mls.... they are serviced regularly (every 5000mls or 3 months) doing all the fluids from diffs to engine oil and all associated filters, now I do this myself which I save on garage costs but I have found them both (touching wood) to be very reliable indeed

Fingers crossed they stay together. I like the engine, but I'm not sure I like a ticking time bomb. However my last D3 was still going strong at 180,000 miles.

There's a theory that if the engine gets past 100,000 miles, it should be ok. Most crankshaft failures happen before 100,000 k miles, but not always.
