Rapier or have I been

[JPA]

Hi,

just bought a 307 rapier HDI 2.0 90BHP 2003 with 100 thousand miles. It was a rush (perhaps panic) buy as my Subaru outback had sadly died and I needed a car asap.
Anyway, thought I'd do the right thing and get her serviced and a new cam belt - ouch. The car runs fine no warning lights etc bit of a clunky gear box and a bit noisy, I know it is a diesel....

The garage informed me (amongst other things) that my car was leaking diesel, but they couldn't find where it was coming from. They said there was diesel in the engine compartment and around the diesel pump, but it was not leaking when the car was running.

When I brought the car home, I noticed a patch of diesel on the road where the car had been parked. The following morning I looked under the car (had parked it in a different spot) no diesel spillage. I started the car and low and behold it was p***ing out under the car. (silly me should have lifted the bonnet at this stage) Took car back to garage and they thought it may be coming from one of the two screws directly facing you on top of the pump.It looked like diesel was pooling there? Told me to take it to diesel specialist.

Diesel specialist price to replace seals on screws around £250 ish, said would take 4 hours @£60 odd per hour. said was a common fault??

Took to Peugeot service, cant see a leak so possibly replace pump @£700 all in, they were more concerned with tyres at 4mm tread..they look good to me and replacing a blown lamp.

conundrum, what should I do????? I kept checking all day and no leak throughout day. Will lift bonnet tomorrow morning before starting her and see if I can see a leak....

Oh the joys of running a car, is it me, why cant I just have a fault that can be easily diagnosed.....words that spring to mind 'it only funning happens to me"

Tricky to trace a leak - the diesel can leak in one place and pool in another.

Worth a punt - check the fuel rail pressure sensor - if it has been replaced they tend to work loose.

Run your finger under the sensor - just after running the car.

Thanks Clanless

being a bit of a novice here, i know where the fuel rail is i think, but where is the fuel rail sensor, what does it look like?

Maybe a stupid question but if I run my finger under it what am I looking/feeling for? leakage, looseness.....

its all a learning curve and dont it feel good (well hopefully it will feel good once I know what i'm feeling for)

Thanks
Jon

Standing at the front of the car - the fuel rail looks like a brass pipe running across the top the cylinder head - you will see that it branches off to each of the cylinders - the sensor is screwed into the middle, top of the rail with some wires coming from it.

Yes, run your finger under the sensor where it joins up with the rail - it won't feel loose, but you will get diesel on your finger if its leaking.

The sensor is a cylinder, part of which is hexagonal so that a spanner can gain purchase.

It if is loose be careful when you tighten it up - as the fuel rail will split if you tighten too much.

Once again, thank you so much for your time Clanless.

Will try what you suggest tomorrow morning, inspect and tighten carefully if needed.

Will up date with how I get on, as so many threads just evaporate without conclusion. Hopefully it might help someone else in the future.

Into the great wide yonder

long shot but it could be the hoses coming from the intank pump look at the two pipes around top near the crank sensor white plug, as when your cam belt is getting done some guys remove these pipes worth a check,

the fuel rail sensor has a big red plug on it or sometimes yellow as ive seen

also check your pipes from the fuel filter housing going to your fuel pump and make sure they are ok

Hi Clanless and CMax,

found the leak Friday morning, started car and diesel bubbling from seal on top of fuel pump. Strange as it only leaks for about 20 seconds first thing in the morning after cars been sitting there all night, didn't leak throughout day, even when the car was left to cool down for a few hours...

Anyway took it to Peugeot dealer, who wanted to change pump and cam belt @ £700 (even though I told them cam belt just changed a few days prior)..

So took it to fuel injection specialists who replaced seals and checked pump @£260. Leak now gone, happy days.
