Nyloc nuts on a turbo exhaust?
[Edited on 10-1-12 by MakeEverything]
where do the wastegate gases go?
Nylocks don't like turbo temperatures.
Gotta be 
Thanks gents. I just wanted to know I wasn't losing it.
I won't bore you with all the history. Suffice to say the perpetrator of this horror is a mechanic somewhere north of the border, well known in
Uno Turbo circles, revered by a bunch of people on bookface as some sort of demigod and has lots of misguided people eating out of his hand. I called
him out a couple of times for dodgy advice to others and I have been crucified and character assassinated as a result. The pic above shows his latest
masterpiece.
For myself, I have degrees in aeronautical and civil engineering and I work as a specialist structural/civil consultant in railways. I have assisted
(for free - even though I take the professional liability) a couple of people here. I have a number of Fiat/Lancia restorations and major
modifications on the go. One of the jibes at me is I pay a guy to do my fabrication work for me, so I must be a numpty.
I rest my case.
Edit: You got 2 out of 2 deliberate mistakes!

At least they'll undo easily when the time comes
If you do leather him forhis Nyloc error, just make sure that this photo wasn't taken at a build-up/temporary stage...
He's been running it and tuning it on MegaSquirt 
http://www.facebook.com/groups/130553130294145/
He also advocates fitting a lower on/off temperature rad fan switch to improve cooling on an otherwise standard tintop. Can't imagine why we all
don't have rad fans running continuously to really improve cooling?
Anyway, enough of the bitching. I'll shut up now.

As I explained to a lad i work with (on more than one occasion) - is it worth the hassle?
Brass nuts on steel studs on exhaust.
No, but when this puffed up "professional mechanic" gives advice that will make an innocent trusting punter go out and buy a fan switch he doesn't need and then proceed to damage his engine through overcooling, I felt the need to put him right. Now it seems I'm a sad old drunken bitch. Just wanted to get it off my chest as they say.
Some "experts" are only so because of their own disillusions.
Non heat treated pipe approx 3" from exhaust?
Yes, good spot. The engine is not a standard Uno Turbo, it's using an X1/9 block. Hence he has had to use the coolant drain plug as his coolant feed to the turbo. It is closer to the exhaust than the UT's water feed would be. So even though it carries coolant it will perish. Turbo X1/9s build up fearsome heat under the lid as it's so cramped with no airflow.
The evidence he's been running it like this is there in the oozing melted nylon from the nylocks, so not a build up photo..
I'm looking at the pic on an old laptop - And to me, it could also look like it's been on/off a few times, so the nylon often gets stripped
away in a similar helical manner. (In my humble opinion)
Either way, I merely wanted to prevent the OP looking silly as her first few posts seem to carry a genuine sense of care for her fellow Fiat lovers...
there is a rubber hose rite near the down pipe thats gonna melt pretty quick
Thanks Steve, you can see wisps of nylon string hanging off the nuts, obviously melted, but I think the nylocs are the least of his worries.
Anyway, I'm not going to go on about it, just wanted my sanity confirmed!

If that's the waste gate actuating arm in the top left corner then it looks like he has managed to shroud this with his 3/8" plate, the
result will be a broken turbo in short order as it will over speed and stall rapidly... not good, there should be a blended in second pipe IMHO
joining the top.
The nasty fast turn and size does not help power either, I expect it makes the pressure okay but will be consuming a lot of power to do so.
And I am no expert, if it looks wrong it probally is wrong
Its a fiat
What do i win?

can you mention the name of this guy? im not wanting a big slating match, just curious as to who he is. otherwise every business up here will be
avoided

Must be a photoshop. It's a fiat that doesn't look like this:
Is that an Alfa parked next to it Benzine?
Thats the same car only a day later, it again rained!!
It is NOT my intention to ruin his business. He does some very good work - his UT and his loopy missus' X1/9 are very very nice and a credit to
him, and I have said so too. However, I do not take kindly to character assassination on failbook, the like of which astounded me, especially as many
of the mob that crucified me I have helped in the past and often called me a "guru." He has got the muggins group admin eating out of his
hand, so of course any riposte is simply deleted or the riposter banned. Thus the 400 odd members who do not know me from Adam all think I'm a
nutty drunk (hmm, they may be right after all!).
The guy is all mouth and trousers and it was high time for him to be debagged. The last straw was when he was prepared to let a trusting punter spend
unnecessary money and potentially damage his engine so that the great Whyte hope could score a point over the UK X1/9 Owners Club. But that is another
story!
I just wanted some assurance that I wasn't losing the plot, so I thought I would consult the collective wisdom here - thank you for your
thoughts.
There, I've said more than enough. It really isn't worth the hassle but when some innocent car owner is allowed to suffer for someone's
egotism I think I should speak up. Sorry everybody.

Wowzers! I've just had a read through some of those posts on FB! That's my fill of crankyness for the rest of 2012!
Obviously, I only know what I've read on there and on here but blimey, if you don't like what folks say, just ignore them, don't spend
ages hating them! Hate doesn't hurt those you're hating. It just twists you up. Peace out little Fiaty folks.
Just to add: Racheal, you're welcome to share my Jaffa Cakes as as a comforting cakey snack.
Haha thanks for the jaffa cakes Owelly!
Edited: I shouldn't be bringing my spats here.

note to self...must take nylocs of my exhaust manifold.......
There's no huge problem with using nylocs on your manifolds or turbo, as long as you're not relying on the nylon bit to stop them from coming loose. And you don't mind the smell of burning nylon....
Well looking at the picture...
Nylocks on an manifold. Not idea, but as Owelly says, the nylon is only there to prevent the nut coming off if it works loose.
The studs and bolts they're on are too short for them to work anyway. Should those be bolts?
The pipe bend is too tight to be idea but can understand the packaging constraints.
The rubber hos will melt that close to the pipe.
The wastegate in blocked.
The nut top left of the picture looks like it might be cross threaded.
Nice to see you on the friendly forum Rach, far too much bickering on
exie site for me - stuff 'em !
Cheers Keith

Thanks Keith,
I understand your comment, sadly much of the bickering has a common denominator.
It has come to my attention that posters in this thread may receive messages from very recently joined "members." I am very sorry for this,
this guy has a track record of using sock puppets to attack anyone who offends him. Please report them.
Again, I apologise for dragging a troll or trolls here. I would be happy if this thread disappeared along with said trolls.
Regards to all,
Rachael
Heh they can message me all they want
Thing is he's going to give someone duff advice one day and then someone else is going to give that guy a more convincing argument as to why
previous advice was duff, probably while putting it on or taking it off the back of an AA truck (giving the second advice more impetus)
Then again surely anyone who's not a moron would check any advice somewhere else until it's proven to be regularly good advice? It's
why I ask most of my questions on here because together we know pretty much everything
That may be true for those of us who have some car knowledge, but there are a lot of innocent owners who rely on and expect a "professional" to give the correct advice. That's what worries me most. This guy was given a "Technical Advisor" post in the UK X1/9 OC (we trusted him too), imagine how that reflects on the club.
