Thread: Long term running costs of used Disco 3/4

The crankshaft/bearings were modified in 2.7 D4,the tensioner belt issue was sorted mid D3,and there were a few injector issues that destroyed engines.

Injecter problems can occur in any diesel engine,but rare in D3/D4.

Not like the D4D tojo engines that have had numerous issues.

Overall there were few issues as others have said.

The 2.7 engine in the D4 seems to have very little issues(maybe due to them being newer as well),although the 3l seems to be having a few turbo and other issues.

There are some good threads on DISCO3.CO.UK on engine issues.

Including a 3.0 with a snapped crank after main bearing shells span!

They sure are.

Ok so:
D3 = V8
D4 = TDV6
Best of both worlds = D4 V8 (if they get crushed by depreciation)

Sound about right?

Your logic is impeccable Cap'n!

To be honest, best thing to do is go and drive one of each, and keep looking until you find the one that stands out. Doesn't cost anything to look.

D4 V8 is very very nice.
