Title: WTF - Tech Note on service - Lower Turbo Pipe Leaking
Post by: nc35 on September 03, 2009, 10:41:20 pm
Hi All

Just spending a little time looking through the paperwork that cam with my car.

Just over a month ago the car was serviced at Smith Knight Faye, Bury.  There is a Technicians note that " OSF Lower Turbo Pipe Leaking"

Can anyone tell me what this means, is it an easy fix and why on earth wasn't it fixed.

Dealers for you I suppose

Cheers

Lee

Probably oil leaking from one of the pi$$ poor joints in the pressure pipework.  Quite common.

If you are under wty ask them to sort it.

Nope - 4yrs old with aftermarket warranty...

Is it a DIY fix?

I think they normally replace the pipe, IIRC the seals aren't a seperate pipe.

There is a pipe that runs from the turbo out, round  towards the front, past the bottom pulley and on to the intercooler.  I suspect it's this one they mean.

The turbo impeller shaft bearing floats on oil, which is supplied by pipework. This is the only pipe I know that could leak and it is not good :scared:

Think I am going to invest in a Haynes manual.
Try and sort this myself, you obviously can't trust anyone any more  :confused:

I'd go with Stu's theory too. Turbo to intercooler pipes can often slightly leak under boost. It would be worth phoning the dealer and asking to speak to the techie who did the service whilst it's still fairly fresh in his memory. He'd also be able to give you his opinion on whether he'd recommend you did something about it now or wait until the next service to see if it had deteriorated any further. An intercooler pipe will be under more pressure if the car is re-mapped and running higher boost so that can exacerbate a problem.
On my last service I was told an intercooler connection had a slight leak but not to be overly bothered about it as it was very minor. The connector can't be bought seperately (as above) so a new pipe would be required, likely cost of around £50.

....Which is why I upgraded all my turbo piping as a precautionary measure. VW, and others, don't manufacture their cars to accommodate aftermarket tuning.

The dealer isn't doing anything wrong by informing you of the leak - In fact quite the contrary - It's up to you to read the paperwork and to remedy, or instruct them to remedy, potential problems accordingly. However, a more helpful dealer would go through the paperwork details with you at the time of payment.

Got to ask....

What are all those pipes??

It's a Forge (or similar) Silicone Intercooler hose kit, a Forge (or similar) Throttle Body hose, a Neuspeed Turbo Out pipe and a Neuspeed Inlet pipe.

....Substitute SAMCO for Forge and it's called "Turbo Hose Kit" by SAMCO.

Spot on, Stu. But no prizes! :drinking:

Don't suppose any of that kit is what I need?
Bit cheeky but is any of it for sale?
Sorry to ask

....Do you mean the oem pipes in my pic, Lee?

Well - I really have no idea...

Are any of the other bits availbe?  And how much?

One of the other posts said that OEM wasn't very good.

Also where are you?  Can possibly collect and pick your brains as to installing them...

Cheers

@ Lee:

What my pic is showing is the new parts (now fitted on my car) alongside the stock parts. I took the pic to show people a comparison.

The only parts I may be willing to consider selling are the stock parts but I'm slightly inclined to keep the hoses as emergency spares as SAMCO take so long to get.

Ooops sorry  :ashamed:

I wouldn't be too hasty to splash out on the pipe Robin displays as for one they all rely on you taking the O seals from your current setup to fit to them and secondly they connect in much the same manner as the OEM ones.

Don't get me wrong they have their place, I ran the Neuspeed outlet pipe for a while with some good results but it's a lot of dollar to be splashing out in one hit.

....I agree with you Stu.

Generally I think that most Neuspeed products don't deliver much extra. However, for whatever little it's worth, the SAMCO ally connections are top notch and so is the quality of their silicone hose construction.

I didn't have any logging done but the engine did feel as if it was freer revving after the installation. Placebo?

Anyway, you know how much I don't mind splashing out money. There's no point me having regrets and I'm glad of the SAMCO bits.

I wasn't trying to say the products aren't good simply trying to say in this case it might not be ideally suited to the OP's needs.  FWIW I thought after fitting the Turbo Outlet that it had made an improvement.

I like the Neuspeed stuff, some of it is on a par with APR in terms of quality.

....Well, I didn't find much of an improvement after fitting these particular Neuspeed components on my particular car, other than a slightly freer revving engine as I said - Certainly not the degree of improvement that their blurb suggested. Quite expensive too. But at least I am confident my boost hoses are more durable.

Neuspeed stuff might be ok in terms of quality but personally I would always also check what other brands offer the same before buying in the future. Our purchasing decisions all come down to our individual experiences.

I was under the impression that VW built in some sort of additional stress / tollerance margine of 30-40% into their products. If that's the case you may expect the oem products to withstand moderate performance increases.

....Yes, I've been told the same - Approx +40% headroom - Not an exact science though. I guess it's a major contributor to that reputation of strong build. However, it won't be applied to every single one of the zillion components which VW use in manufacturing a car.

Regarding the turbo piping, what I have done will doubtless have increased the tolerance headroom waaaay beyond any +40% (I'm running between 240-270bhp according to which rolling-road), but I happened to get offered some SAMCO hoses and then decided I may as well add the Neuspeed Turbo Charge and Discharge pipes. It was one of those totally unplanned mods - Rather random.

Just to update
had the engine cover off today and no sign of a leek anywhere
don't really know what to look for water/oil or signs of.
Can't see anything at all to be a worry.
But the front left bracket for the cover was nearly off bolt nearly out,
and only one screw in the air intake at the front.
Less and less impressed with dealer mechanics.

Going to post else where, but any suggestions for a indie up north?
Perferably West Yorks / poss Manchester

I think the leak in question would be low down on the drivers side near the wheel arch.  Visible from underneath.

Bit of a resurection but...

Robin, would you say the Samcos with ally ends are less prone to the oring failure found on mapped cars?

Thanks

....G'morning, daddy!

I think so. Although expensive (and the Forge are probably just as good if they are lined), the SAMCO hoses are top-notch quality construction. Even when I ran over something sharp and a lower hose was cut it didn't leak. A remapped car will be putting through more pressure and although I haven't heard of splits/failures on the OEM Mk5 GTI's turbo hoses it was apparently quite common on the modded Mk4's.

If you fit some, go for stainless steel jubilee clips - No need to spoil a ship for the sake of a halfpenny worth of tar.

They certainly give peace of mind and extended life. The OEM appear somewhat naff by comparison. Not cheap though.  :happy2:

Thanks for your reply ;)

I didnt see my boy all day yesterday for sorting the house for an inspection that should be happening now, housing officer hasnt turned up.  Cheers  :fighting:

Did I miss where you sourced yours from?  Samco Direct? Cost?  I think Awesome do the Forge turbo hoses but I will compare reviews and prices  :happy2:

thanks again

Next engine mod (and probably last before funds dry right up!) will likely be the forge turbo hose kit and the Neuspeed Discharge pipes

Although Ive heard negative comments about theForge throttle body pipe & the OEM one does the job.

This overall mod including Neuspeed pipes is not the sort which will have an obvious benefit and cause you to exclaim "wow!".
