Hi,
My Disco TD5 (04 plate) has about 80k miles on it, and I run on some pretty dodgy fuel brews, using quite a bit of recovered oils, and old engine oil.
Is uses these fine on about a 50-50 mix with pump fuel (I NEVER use red diesel) but a recent lot of recovered oil has had too much petrol in it, and the TD5 doesn't like that. It was very slow to fire up, and smoky, but once wrmed up and cruising, it drove along very nicely.
Today I decided to swap the glow plugs for 4 new DENSO DG-182
The job was a bit fiddly but not too bad. I started at the front. Got the wire off, and after a bit of wiggling to and fro the plug came loose and out. It had been fitted dry. It LOOKED PERFECT.
It is a BERU 0 100 226 255
It had not been leaking, and the tip appeared intact. I began to regret going to the trouble of taking it out.
Then I measured it on a leccy meter it was DEAD --- d-e-a-d.
So I fitted a Denso with some copper-grease, and then did the other three.
All four Beru plugs that I pulled out LOOKED the same; they LOOKED fine, but all four of them are open circuit, as in electrically DEAD. No Glow.
I will post tomorrow if it starts any better, and if the smoky first minutes are any better. Tomorrow I am also going to check that return pipe from the fuel filter head back to the tank.
