I wondered why my fuel economy was not so good the other day and when I looked under the bonnet I found my Injection pump was starting to leak.
So I was wondering if anyone else has had problems with their diesel injector pump leaking?
It's a 1992 model, 2.8 TD
And can I blame it on the low sulphur diesel that we are now using in Australia?
After 4 years this is the first major problem I have had with the mighty Rocky. I'll be much happier if I can blame it on the Government.
Not sure exactly where it's leaking from but I'll have a good look tomorrow.
I'll keep you all posted on the outcome.

Leaking Injection Pump for Diesel Rocky
Moderator: Tiny
Well after much crawling around and back bending I have worked out it is leaking from a gasket on the back of the pump.
So I'm going have to pull the damm thing out and get it fixed. (when I get around to it)
A turd of a job cos the timing belt and all that other stuff that goes with it has to come off. It's a shame the timing belt is less than half way through it's life, oh well good practice for next time. :evil:
And look I even used one of them there fancy things. :mad:
See there's another one.

Stu, I found out a bit of info on the low sulfur diesel last night- (now this is from memory!) apparently a lot of pre '94 diesel engine fuel pumps use nitrile rubber seals, and this can be affected by the low sulfur. The sulfur acts as a lubricant in the diesel, and the new stuff has other additives to compensate. The newer diesel engines all have viton rubber seals that cope fine with the low sulfur fuel.
A few places in Queensland- where you live?- were trialing an ultra low sulfur diesel and this is apparently the cause of most seal failures. The normal low sulfur stuff isn't supposed to be that bad.
The info was from a Isuzu truck magazine.

I put a post on the General forum with all the gory details.
Basically the seals were OK but I had water in my fuel that stuffed it up.
Don't know if it was me or the previous owner.
A very expensive lesson.
So now I'm going to put in a CAV filter with water trap before the existing standard filter. CAV unit has a glass bowl so at least I can see the quality of fuel.
