Hiya, im gunna attemp to fix my exhaust leak today. Its leaking from just underneath the turbo, where the "trousers" part joins to the downpipe i think. There is no gasket in there, and its coming out the side. So what would be the best stuff to use to re-join it?

Diagram.....




Cheers,
Mike.

 

It may be damaged as it shouldn't leak at all. I doubt you'll find any gasket paste that will survive.

 

Mike,

No gaskets are used or needed, you've just got to make sure the
mating surfaces are perfectly flat and clean. Then, if possible use
NEW bolts/nuts that are evenly done up (progresively), and tight.

=========================================

 

Some steel gaskets are available, but I will put up a
picture a bit later of what happens to them over time

 

oh dear. sounds nasty. i will have to check that it is ok.

Cheers
Mike

 

also refit using new locking nuts - normal nuts will vibrate loose over the space of a few miles

or use them washers with the locking tabs that fold onto normal nuts to lock them in place

 

maybe they could be machined(spell) skimed ?

 

up. as i need to do it today. Cheers.

 

OK Mike,

This STEEL gasket was fitted to a small turbo Es Cossie,
running no more than 1.2 BAR boost (about 17 LBS/PSI)......

Because one of the nuts is very difficult to tighten up on
the 4x4 manifold, it will allways be the weak point
(unless it is correctlly/evenly tightened)........

This failure is NOT the fault of the steel gasket as such -
but you can see from the pics, the damage is the result of
incorrect fitting, it highlights the fact thar ALL 4 nuts/bolts need
to be done up correctly, and checked for tightness -
perhaps every 2k miles or so

 

get the 2 surfaces ground flat......

 

ok, been outside all day, and found out it wasnt just that, that was leaking. The manifold gasket has also blown on number1, so i have stripped it all down, and its ready for a new gasket. Bollox.

Mike

 

your lucky it's not a 4b4 manifold they are a total coont to get off

 

oh dear. Are they different then?

Mike.

 

yeah, tis a pain in the arse!

 

4x4 are a rite fookin nightmare.!!!!!!!!!!!!!!!!!!!!!!
