Smell of diesel

[Jimbo]

The engine bay on the Disco has started to stink of unburnt diesel, so I'm suspecting that there's a leak of some sort somewhere - I can't see anything physically dripping or leaking, but the stink is definitely getting worse, and is more noticable after a run.

Any clues on where to look ?

Check the Spillways. Little short hoses beween the injectors. Datalas had to do them for the same reason and mine are weeping.

Hmm, just looked at my RAVE CD - seems the Td5 doesn't have spillways (not ones that are 'external' anyhow), the high pressure fuel line connects to a 'fuel pressure regulator' on the side of the block, and the return comes out of the same regulator and goes back to the tank via a 'fuel cooler'.........time to getmy hands dirty  :roll:

Jim,

The presure regulator would be the best place to start.  They are known to fail.

I thought mine had gone earlier in the year, but thankfully it turned out to be something less serious (was the front axle breather spurting out oil for some reason).

If it is that, make sure they order the right one for your vehicle.  There are two variations.

I'm just putting 2 and 2 together and making 5 here.........I've got another problem whereby when I plant my right foot to the floor the auto box plays silly whatsits - it changes up a gear, and then back down, then up, then down........if I back off the loud pedal it changes up ok - I thought the 'box was on its last legs, but maybe its a fuel starvation problem, and maybe it's the pressure regulator.....????

One of the mags did a feature on changing the fuel pressure reg a few months back, IIRC it's a royal PITA to do - perhaps my tame mechanic fancies doing me yet another favour  :roll:

spillways on mine are leaking a good one as well, I have a trail of derv down the side ofthe engine they're that bad, how do you fix them and where can you get new spillways from

Tis just fuel hose but its a fiddly job. Cut the old ones off, cut new hose to length, slip them on (skin knuckles, gouge pipe end out etc) and jobs a goddun.

The hose is widely available, had my last ones from Halfords

or you could go in to Bearmach Gareth and get them ready made, part number is MJN100910, but that will cost you!

its not that hard to do

 :lol:  shouldnt take anymore than an hour to change

I'm guessing that's an hour in an ideal world, with all the tools and a nice warm workshop.............perhaps I'll allow a little longer, and dodge the rain showers !!

Mikey - what do you reckon, could this be the cause of my misbehaving auto box ?
