Exhaust Blowing Around Turbo

[Scorpiorefugee]

After a longish spell of trouble free motoring it's all going wrong.

Gal no 1 (110 bhp) has steering problems still unresolved. - previous post.

Gal no 2 (52 115) has now developed a problem somewhere round the turbo/exhaust. there is some loss of power but the garage has had a quick look and can see nothing obvious. SWMBO has complained of a slight noise for about a year but she is now in hospital and the noise has got a lot worse, although I did 300 miles yesterday without further deterioration.

 

I'm now down to her pristine Picasso and if I break that I'm in serious trouble so I'm hoping someone can give me a bit of guidance here before I set the garage loose on it.

 

The garage who are totally trustworthy have had a look but, in spite of blocking the exhause to build pressure and revving against the clutch, couldn't see where it was coming from.

 

 

???? please.

???? please.

 

Please what ????

 

 

:wacko:

 

 

 

Whoosing/hissing noise and associated loss of power is usually a leak in the boost pipework. Check the big pipe joints and the intercooler for hole damage or pipes disconnected.

 

Steering noise is probably down to the ebay special you bought. BTW when I had my cambelt changed 2 years ago at the VW dealer, they offered to change the PAS pump for

Thanks SeatKid,

 

Please.... anything, I'm too busy dashing back and forth to hospital, doing cleaning, washing, cooking and ironing to get too involved at the moment.

 

Re the steering box, I agree. The old pump was fine until it got bumped. Sadly, there is no trade in value on it so it's full whack for a recon and I saw those at about

May be worth taking the EGR valve body off and cleaning it out, my thinking is that it will react to the throttle off quickest, or even (like mine is now permanently) disconnect and block the vaccum pipes to it and give it a try before you do anything else.

Thanks Richard,

 

It certainly sounds like that sort of area. I've got it booked in for a service on Monday so I'll ask them to look at that. I've tangled with my old 110 AFN unit in that area but I've never had to go near this one and I justdon't have the time right now.

This is beginning to sound expensive....

 

Exhaust and cat removed and very little exhaust gas coming out - seems blocked.

 

It sounds like the turbo has disintegrated or something else (???) is blocking it. Has anyone any experience of this?

Best price garage can fine one is is

Thanks again for your interest Richard. The story is a litle complicated. The garage is working on this piecemeal as they are very busy and I have no immediate need for the vehicle but they have said that there seems to be exhaust leakage though the diaphragm and it is doubtful if anything can be done with it It certainly seems to be making quite severe exhaust blowing noises and getting rapidly worse.

 

However, it may well be worth trying to block it off as you suggest. It does seem that irrepairable failure is s bit unusual. I'll ask them to give it a try.

 

I've had a look at the item details that you recommended and it all sounds too good to be true. Dou you have any experience of these things?

No experience of the straight though pipe but has to be better than a bloked off system that still has a valve stem restricting air flow a little like mine.

 

I didnt fit one as i am a cheap skate, and wanted to be able to reinstate it if there was a problem, but as i said up to now its fine.

Richard.

 

I decided to order one as the garage man said the old one was blowing out of the diaphragm and once it had been removed they would have to push it in and out until we sorted a replacement so I thought it was the simplest way out.

 

I shall report back but it may take a week or so to assess it.

 

I hope you don't mind but I passed your comments and link on to a more recent topic as it semmed very relevant. It certainly seems that this could be a useful mod if a little expensive for the parts provided but I suppost that it is not unreasonable for High quality low volume products. Also, having looked at comments on other forums, it seems that the after sales support is very good.
