So I have seen a leak dripping from the engine area slightly towards the drivers side, diesel in smell to my untrained nose. also the back of my terrano is caked in something greasy which leaves a black mark on my finger when I rub over it. is it a diesel leak seem to be getting about 300 miles to a tank

thanks in advance for any advice
 
Have a look at your fuel lines? They're on the RH chassis rail. Mine sprung a leak a wee while ago, but it was an easy leak to find as it was actually dripping.

Might not be that, of course. But it's worth a look. There are some really knowledgeable people here though, so I'm sure you'll get better advice than mine :thumb2
 
i can see it dripping too and i have just spotted an advisory on the MOT in July for corrosion on the fuel lines
 
That could be your leak then :thumb2

I know a lot of guys run flexible hose alongside the existing hard pipes. That's my plan too when I get the chance, but for the time being I used a section of flexible pipe held in place with a jubilee clip
 
Fuel lines are an easy DIY replacement. I did both of mine in an afternoon just with a set of ramps.

If they are leaking it is easier to replace the whole lot rather than repair the leak.

Are they expensive to replace?
Does this explain all the shite on the back of my wagon? (excuse my french)
 
This is what I did:

Materials used:

5 mtrs x 6mm int. dia. fuel hose
5 mtrs x 10mm int. dia fuel hose
2 x jubilee clips
Cable ties x good handful
Insulation tape x small amount

Process:

Put insulation tape over open ends of each length of hose to stop chassis crap getting in the new fuel hose.
Taped two hoses together at one end to make it easier to thread through chassis etc.
Threaded pipes through access panel in boot through chassis following route of existing pipes.
Removed metal air scoop surround and removed fixing bolt for dipstick to allow a bit of extra hand room.
Removed existing pipes in engine bay and fitted new pipes.
Removed old rubber hoses from engine bay.
Working from engine bay backwards, cable-tied new pipes to existing fuel lines as they quite substantial to support the flexible new hose.
Connected new hoses to tank in boot access.
Turned truck over, started, ran, then died.
Pumped fuel primer, turned it over, pumped again, turned over, etc., until it started and ran.
At the lowest point of the old fuel lines, cut through both feed and return to drain diesel out of lines.

http://www.beal.org.uk/ is where I got my pipes from.

Cost less than £30.00 for all the materials.

You need to check what size feed and return pipes you have, various people on here gave me two or three different sizes, and the conclusion we all came to was that some vehicles seem to have different sizes.

I am no expert spanner wielder, but it was an easy job.

Hope this helps.

If it's coming from engine bay area it can also be the injector leak off pipes. Small bore rubber pipes that connect each injector, one of them is a stop end (blank off) pipe. Think it drops down side of engine block starter motor area.

If you remove the intercooler you can see and access the pipes easily.
 
depends if you have Bosch or Zexel pump, the latter has metal leak off pipes, you can identify by the Maff if Hitachi then Zexel, Rick
 
I too have what I thought was an oil leak but am not losing oil, could it be the metal leak off pipes leaking and diluting the 20 years of oil on the engine? I get about half a tea spoon full after a run, made a real mess of the block paving
If so where should I start looking
I have a TD so no intercooler to move, but I clearly have to move something to carefully check the pipes but not sure what
Which route does the leak off pipe take back to the tank?
There seems to be a "T" piece in the return fuel line drivers side on the chassis under the drivers seat, could that be for the leak off pipe?
 
sound like you guys know the problem, anyone have a rough idea what it would cost in a garage not sure I am up to the DIY job,

also does anyone know if this explains what the back of my wagon is caked in??
 
Can't really help on that one. On my first T2 I had a fuel line repaired at a local garage and he charged me £80 (5 years ago), don't know what they would charge for a full replacement.

:nenau
 
no one has been able to answer the question about does this explain why the back of my truck is caked in caca?
 
Could be its the main fuel lines, they often leak above rear axle. Even if its leak off pipes or fuel lines at the front then could be if you've been traveling at speed that it has been drawn under the car and caught in the turbulence and splatted the back of the car.

Your best option is to either have a good look yourself or get a garage to do it for you. If I were looking I would remove rh front wheel, pull the rubber guard away so that I could see into the engine bay and have a good look with a torch and mirror. Then also have a look under the rear at the rh side above the axle. Remember though if jacking up always support car with an appropriate axle stand.
 
sorry your right but i cleaned my car today :(
personally i think it is diesel
 
Take a look at the downloads section, im sure someone created a download for replacing fuel lines.
 
thats what i was thinking diesel drawn from under neath splattered up the back

thanks for your help!!!!
