Title: Pas pipe advice needed
Post by: Greenbay packer on 23 May 2019, 10:20:07
Hello everyone,
I have a leak from a badly rusted pas pipe of my 1996 V6 estate and would appreciate some information about the part. Its the lower of the two pipes visible in the gap in the front bumper wraparound. Its course is a bit difficult to trace but as far as I can see one end finishes at a jubilee clip more or less below the air filter box and the other end fits to the pas pump. I'd be grateful for answers to all or any of the questions below please.

1) have I traced the course of the pipe correctly and is it easy to remove?

2) does anyone have the part number for this pipe and can you tell me if it was common to all Omegas or just to the V6?

3) does anyone know where I can get one of these pipes either new or good secondhand?

4) if I get desperate could the pipe be repaired by cutting back to a good part of the steel pipe and adding a section of hose secured by jubilee clips, or will there be too much pressure in the system to get the clips to seal?

Thanks for all advice given. I was planning add some photos but can't find a way of doing so here without signing up to photobucket - is there a way to do this?.
Graham

Option 4. It's ugly, but that's the only 'problem' with it.
Easy,  cheap and you could have it done before lunch.  >:(

Thanks, so its not under high pressure then and jubilee clips should seal it?

Looking at it again I may not have traced the course of the leaking lower pipe correctly on the passenger side of the car - I thought it was going to the pas pump but maybe not, can anyone confirm please?

a correctly sized Jubilee clip will work on any pressurised system you'll find on these cars. PAS isn't particularly high pressure.

Thanks for that - I had visions of replacing one leak with two new ones!

I measured the pressure on the LC a few weeks back. At the output from the pump it's 95-100 bar, or 1500psi ish, on full lock. So I wouldn't want anything other than a faultless pipe between the pump and the steering box because a leak in a 100 bar pipe is going to spray fluid a long way and make a hell of a mess.

The other pipes, including the ones from the box back to the reservoir via the radiator carry much less pressure and are eminently bodge-able. Just be aware that the fluid does get quite hot (hence the need for a rad.

I may have misread this, but it seems BG offered you one in the second post. :-\

I feared that this might be the case.

I had the very same problem a few months back and chose option 4 albeit with 2 clamps at each end and have had no problems since, there is no cooler rad for the pas system as it relies on the pipe loop in that gap in the bumper for it's cooling effect.

Thanks for this reply. I'm probably going to have a go at repairing as there's not a lot to lose, but what to know where I can get hold of a pipe if it doesn't work.

I've messaged him and he's going to get back to me in a week or two.

It would be a big help if someone could confirm where the lower of the two pipes finishes up on the passenger side of the vehicle please. I initially thought it ends up screwed into the pas pump itself, but now I'm not so sure and its a bugger to trace its course.

Also, does anyone have a part number for the lower pipe? If I attempt a repair and that fails I'd like to know where I can get the part if I can't get one through here.

Thanks again,
Graham

The same pipe has gone on my 2.2 TDI.  The garage said it was no longer available and will be replacing it with generic pipe.

Looks like it goes to the reservoir.

Sorry, don't know why I thought yours was a diesel but think they end up in the same place.  :y

The pipes go from the steering box along the chassis rails,across the front then up the chassis rails on the other side to the resovoiar and pump. It's a bit awkward to post.

You just have posted it.  ;D

Correction. 

The pipe is metal and they tried cutting out the corroded bit and replacing it with braided hose but the hose burst.  They then fitted in a short section of copper pipe.

That being said Mrs Google quickly found flexible pipe capable of withstanding 3250 psi (224 bar) - see High Pressure Flexible Hose - annular (https://www.flexible-hose.org/flexible-metal-hose/high-pressure-flexible-hose.html)
