Please help identify this part.

Hi all and thank you for looking in on this post, I am so glad to have found this forum.

The skinny.....

I have a family school run 406 (1.8 LX 2001) that has been faultless (apart from the AC having a mind of its own and only working in minus 20c) up till now. It started running lumpy and developed a odd rattle from what seemed like the timing belt case, but belt was fine. Then it started to sound like my 400bhp EVO, not good! Got some really funny looks as folks turned to see the 1000 bhp Bugatti Veyron blast by only to be met with a silver pug full of kids and me hiding under the dashboard.

Anyway, I looked all over for problems and found nothing until I noticed oil over the air filter box. After checking each pipe I found no clues as the oil had sprayed all over most of them. Until I wiggled one and it came apart in my hands! It had split on two junctions and was spewing oil, not gallons, but still going to be a good hour of gunking. I disconnected the pipe that ran from the engine block to the carb and thought "great, job done"....... except can I find out what it is? No! You try "order French black hose" into Google, its quite eye opening, but not I fear much use to my car?

So my obvious question is.....

A: What is it called so I can order one? (2001 / 406 / 1.8 LX)

B: Could It have damaged anything else I should know about? I am not sure how long it could have been holed as I am used to a much faster car and just thought it was just slow because it just was a slow car.

C: What would you recommenced I check before replacing part and going again?

D: Should I get a genuine new part or is a oldie breakers special okay?

The mystery part......



Many many thanks in advance! Safe miles folks....

That is the engine breather piping.

You can fit a second hand one if you find one.

The rattle could be related to the aux belt tensioner or maybe the crank pulley....not sure if the petrol engined models suffer crank pulley faults like the diesels.

If the rattle can't be identified take the aux belt off and run the engine and see if the noise goes away, this will eliminate the aux belt tensioner....If the noise is still there then the crank pulley may be at fault.

Welcome to the forum btw

Hi & welcome

Could this be it?



Chance find in Service Box.
It lists four (!) 1.8 engines: 92 and 103 (8 valve) and 112 and 117 (16 valve).

At last! I had no idea it would be such a challange to find what it was, thank you all so much! Even the Haynes book of fibs decided to just exclude it like it wasnt important. Now I can get on and order the part, at last! Gotta love the internet.

I will also check out the aux belt tensioner (stupid question, but, is it safe to run it until its fixed, like a "to the garage" run?) if it's failing? I am certainly no mechanic, but I am sure slipping/snapping belts can be terminal, would you run it to the garage, or, fix in situe? It makes the kind of sound like metal is jingling around loosely, like a tinkle, ting ting. It does not sound like its the engine (if you know what I mean) that runs very smoothly. After the engine is well warm it almost fades away totally. Sounds much much worse when first started.

Thank you for the welcome's and help. You time is much apreciated.
