Driving home yesterday I noticed the defender was losing power and was shuddering slightly.

When I got home it stalled at low revs, not due to my clutch control

Anyways, I got out and could smell diesel, its leaking at the injector.

Now I have some theories but i thought I'd check. Either:

1. The pipe is split under the nut

or

2. The injector is blocked and fuel can't get through.

Found out its the pipe thats split, gotta purchase a new one.

yeh happened to mine too, worth getting all four new, as mine all went one after the other! propper pain in the arse, and try make sure you get em on as straight as possible.
