Split Hose

[Bruce]

Hi

There's a long-running issue with my 2003 Aero. It takes 4, 5, 6 - sometimes more attempts before it fires into life. It's turning over fine but just not catching. It's fine when it's running & if i turn it off then on again when the engine is warm - no problems.

So far I have replaced the CPS & DI Cassette with brand new ones & the battery is good too (according to the AA & Main Dealer). The car has been into the Main Dealer here to see if they could find anything. They had it 4 days but found no faults & no codes stored either. It then went into the dealer for a service - replacing spark plugs, fuel filter, & all the other sundries but still the problem persists.

However - after a good bit of messing around, I have found a split hose on the engine block. Hopefully the picture will be attached here so you guys know what I'm talking about. Is it possible that this split is drawing air in & bypassing the air-flow meter & causing my starting problem? The car is also using much more fuel than normal. The split itself is underneath the pipe I've marked between the 2 arrows (which runs round to the 3rd arrow) & most likely caused by the pipe rubbing against the other.

Does anyone know if it's possible to replace just the worn hose, or do I need a whole new breather kit?

Any help would be much appreciated to get this 9-5 back in top shape!!

Thanks

Welcome!

I don't think that there's a breather kit for your car.  The breather kits you read about are for the 9-5 from 1998-2003.  The 2004-on cars have a completely redesigned breather system and engine casting.  And judging by the unpainted cam cover on your engine, your car is a later one.

But you do need to replace the hose.  It is the pipe between the engine and the inlet system to the back of the turbo and it will indeed bypass the air metering and make the car air/fuel mixture run weak.

I'm not with my parts list at the moment, but I should be able to find a part number.  Although I don't think that there's anything very special about the pipe, it needs to be oil resistant and temperature resistant, though.  But otherwise a length of pipe from a roll may do.  In similar circumstances I have cut the pipe at the split and put a piece of copper tube in there with a jubilee clip at each end.

I'm surprised that with all that oil spray around, that a garage didn't find the split straight away.  I'm off in the morning to check that pipe on my car!!

Thanks SGould  I've been lurking on here for a while, having come over from the old forum but haven't had the chance to post until now!

You were quick on saabscene but even quicker here it seems! 10 mins after I'd posted - I've got an answer.

It does seem a little weird. The main dealer has been saying there's an oil leak but it's nothing to worry about. On 28th December when in for the service - they suggested a pressure clean & monitoring! My guess is that they've plugged it in - not found any codes & not rooted around in the engine bay a great deal in order to find the split. I only found it by lifting up the top hose & looking under it. Perhaps there used to be a clip to seperate them? I'm going to fix one up once this is fixed though.

As you suggest - I'll replace the hose with the same again & see if that clears the starting problem. It's odd that it starts without a problem when the engine is warm though. I haven't been out in daylight to find  the other end of the hose - although it can't be too far away I'm sure! If you get a part number then let me know & I'll order the proper piece of kit. If not - no worries & I'll fix one up from some hose.

It's times like this when I miss having Elkparts around

Thanks for your help as always!

Well I haven't looked at that pipe on my car directly but I have got some photos of it taken last year.  It's a 2007 model 9-5.  The pipe seems to be made of a completely different material.  Is your car an earlier 2004/5 car?  If so, it's possible that the pipe material was changed for a reason....

Here's what mine looks like.

Yours definately looks more resilient! Mine is a soft rubber - kinda squishy if that makes sense. Yours seems to be more plasticy! They must have changed it on later models right enough. Mine is a 2003 - though I think it was a December 2003 so may be a 2004 model. I really should know this! It's got the heated rear seat etc - I think it's one of the last "good" Aeros before they stripped them back again in 2004.

If you look at my second picture,you can see the VIN Number (also in the windscreen and on the door sill).  Model year will be the 10th digit. Mine is 7 for 2007.  So yours should be either 3 or 4.

Mine is a 2003 - though I think it was a December 2003 so may be a 2004 model. I really should know this!

What shape are your front fog lights?...

[Bruce]

foglights are the old oval type ones. It's pre-facelift that they did in 2004. I'll check the vin when I get home though.

Here'a the 2004 Crankcase Ventilation System.

Pipe 7 (see attachment), the one that has split was changed during 2004.  So, surely there must have been a problem with the hose you have?

And just for completeness, here's the 1998-2003 system

Been having a think about this....

Your engine picture shows you have a 2004 engine.  So either you have a 2004 model or a replacement engine.  As it was a December 2003 car I reckon it's the original engine and you have a 2004 model.

However, if you have a 2004 car with a front end that looks like this:



Do you have an Aero?  The only 2004 car with the old "Aero" front was the Vector Sport which carried on the 2002-2003 front bumper with the lip under the bumper.

You've got me interested now........

The 2004-5 Aero has a front with round foglights that looks like this attachment:

Hi Folks

I took my picture into the dealer today & ordered the new part. It's on your 1998-2003 diagram SGould and is the hose you described. I also have some more info on my car no I'm home. December is in my head as my other car was registered in December (a Volvo - please don't hate me!). My 9-5 was first registered on 25 March 2003 & the 10th number on the vin is 3. It's an Aero, has heated rear seat, upgraded stereo but no sat-nav. I have attached a pic for clarity!

Hopefully, my replacing the hose will sort out my starting issue! 

[Bruce]

Incidentally - the dealer confirmed that earlier models have a rubber pipe running round the side of the engine & connecting to a metal pipe further back - where newer versions are all metal. I guess there must have been a few problems like mine!

[sgould]

So, you have a March 2003 car with an unpainted cam cover.....  Hmmm! I wonder how that happened?

I'm still not onvinced that you have a 2003 engine as the pipework on the earlier car on my (updated PCV) 2002 looked like this (I can't find any pictures from before I upgraded the PCV):

[sgould]

That picture shows that my 2002 car had a metal pipe.  It was changed.
