Frustrated.. LC Turbo Back Exhaust Studs Rusted?...

[Mo Arif]

Frustrated....

Went to get a custom turbo back exhaust made and fitted for my LC today, and the guy there goes that one of the studs holding the exhaust from the turbo (turbo back) is rusted and the bolt does not come off fully, he said he does not want to snap it and it's a big job putting in a new stud, you will have to remove the turbo etc, now i'm really pissed off, I normally associate rust with Citroens not with fairly modern VAG car. He recommended to leave the turbo back pipe and start the custom exhaust from before the cat, (de-cat) because it won't make a difference, the standard turbo back exhaust pipe looks restricted to me?

has anyone else experienced this? if so, how do I replace those studs? what a waste of time today was.

Lee have you just shamefully stole those recent pics from another forum member

err bttt?

Ok so the turbo back pipe is restrictive, but how do I go about sorting the studs out?

No

This sounds like the guy is making out it's a bigger job than it is?

If it's just a case of grinding the bolt off to feed another one through then you could do that fairly easily i imagine? Try throwing WD40 at it or some other kind of maintenance spray, see if it eases it a bit?

Having not seen that connection yet i may be just running on a load of twoddle..... lol!

And Lee...... LOL! Shameless admission!

IF they do break you need to replace them but soak them in plus-gas, similar to WD40 but better for a few days to help loosen them.

id go back to th guy and tell him hes a positive ass......

the dp will make the biggest difference not the cat back, as said soak the nuts and they will come off, rust will not seize them on.. he sounds like he cant be arsed with the hassle

id be going elsewhere tbh, if the guy doesnt know the dp and cat is the most restrictive part of the system.

I don't think it was much to do with the downpipe, we done a deal on a full turbo back system and the car was on the ramp, he was emphasising that he does not want to be held responsible for a broken stud, and that's it's a hassle to sort it because the turbo is at the back and has to be removed etc etc

Clearly this is going to be a problem to the NEXT person I take it to?

 

[Lodey23]

as mentioned surely its just a case of feeding in a new stud, and my god that OEM down pipe is kack, next for mine may be a blueflame lol

*cough*

The downpipe STUDS and NUTS do often seize.. remember they are seeing 800+'C temperatures and metals will bind and fatigue and its VERY LIKELY, and COMMON for these to seize and snap the stud off.. which is in the turbo's hotside

Access to this in situ is not possible to do a job of trying to drill out and retap for new stud.. and it can lead to turbo off job to spark erode out the broken stud and start over.

These things do happen.. He is not talking cr4p, but how it is..

fully agree with this, the best thing you can do is lube, heat and just gently start working it off undo it a liitle bit, wind it back up squirt some oil, undo it some more, wind it back up squirt it etc etc and you might get lucky,

if not turbo off and you'll have the peace of mind that you've got nice shiney new studs holding the dp on, may be worth upgrading to stainless studs nd nuts if you need new bits

 

[james walker]

not saying hes not right, but would you turn a customer away bill and say you cant fit it for him, or would you just do it.......

would put me off someone like him tbh

You should see the other worktop I have a rocker cover and a inlet manifold on it

That exhaust picture doesn't really do it justice the standard one is very very restrictive and does make a very big difference to performance.
