diesel fuel leak

You paid for a service, he accepted the task ( inferring he deems himself qualified to do it).

Ultimately he took the slack approach not using a suitable tool to correctly torque the plumbing.

With the leaking fuel he has probably left you with an unroadworthy vehicle.

Cheek to suggest any further financial impost on you - maybe a profuse apology and convenient time to rectify it.

thats a joke,

it wasnt leaking before, but is after he did the work,

those pipes are vital they torqued correctly, and there is a tool to torque them up,

Its on him, plain and simple!!!!

Can anyone describe, or have a part number, or name what this torque tool is to torque the fuel lines up, the search has come up zero and the only suggestion is a crows foot spanner. How does this special tool do the job to the correct torque value. I looked at google and ebay also without success. It will be a big job for me to do the manifold clean as I have limited mechanical skills and I don't want to have the car in pieces without being able to get it back correctly together. Thanks John

The pic I've seen looks like a long socket with a slot down the side with a recess in the middle area. This allows it to be slipped over the pipe and turn several degrees.

I was going to get a suitable socket and do some fine delicate adjustments with the angle grinder.

Crows foot spanner, used with standard torque wrench (socket type)


Alternatively you can get a different type of torque wrench, this is mine for torquing up flare nuts on refrigeration systems



If he didn't use the correct tool, make him pay to fix HIS stuff up!!

[RHKTriton]

The crows foot spanner looks tempting but you're not going to get correct torque with that method.

The other reason for a socket type fitting is that you don't really want to put any sideways force on the injector but only rotate the nut.

Thanks for all the comments.

I agree RHK, intuitively the torque would seem to be multiplied by the extra radius / leverage of the crow foot arrangement.

In any case I'm not sure how to get the mechanic to take responsibility or "make" him do anything. He can argue that he has done the job numerous times before and not had the same problem (I only agreed to him doing it on the basis he had done it before).

Is there a documented procedure I can show him that illustrates the tool and the torque and the procedure he should have followed instead of winging it?

Is it even reasonable to expect that an independent mechanic should have had access to the procedure and only have undertaken the work if they did?

Hi I was searching for torque settings for the injector lines for 3.2lt TD 07 triton when I came across this.

I am looking to clean out the intake manifolds and would need to remove the rail and injector lines . I looked up the crows foot & torque wrench information as I was unsure of the difference in the torque setting using the crows foot .

Found this on utube what do u guys think? Mayb this is common knoweledge ... Correct or not ?

Which bit?

I knew that extending it would stuff the settings. Apparently you can calculate the difference and set the torque wrench lower to adjust.

I didn't know the 90 degree trick though. I'll be using that one for sure.

How handy would it be to have the calibration tool there with you though? You could just adjust it on the fly, check the reading and go ahead and use whatever attachment you wanted.

It's a good video to find. I'm glad you shared it.

Did you find the torque settings you were originally looking for?

[RHKTriton]

The are apps for smart phones to do the calculation. To be 100% sure you'd need a second wrench set to the required figure and connect to this with your offset wrench.

I haven't had a chance to follow up but a brief discussion with our local Total tools guy suggested they can get something like the 'special' tool that mitsi use for the injector nuts.

[Cowboy Dave]

Yeah I bought one. Well two actually because the first one sucked. I also got a quite handy injector spanner from the UK that has on open ended flare style 17mm both ends with bends in just the right places to reach inconvenient nuts/bolts.

If he's overtightened it then the pipes will be stuffed anyway and will need replacing. They do have a limited number of uses before they have to be changed because they have been crushed and won't seal properly again. If the rail leaks into the engine itself you can be up for major damage as it will slowly fill your sump. If he doesn't have the correct tools then he will never get it right anyway. Not much of a mechanic by the sounds of it. You should only take a diesel to a diesel specialist for those types of work as at least they know what they are doing as they do it all day long.
For me, yes i know he stuffed up and should be fixing it but i would tell him off and get it done properly somewhere else or do it myself. At least i would know it was fixed.

Suction control valve my guess

I am looking at another car for my wife and wonder if the MQ, Outlander and Pajero sport diesels still need fuel lines removed for tappet adjustment, thanks for any advice. John.
