118 The source of all misery Cracked back manifold
Well, I have the same experience with my XM V6. But the garage noticed that the back exhaust manifold
(is this proper Englisch?) was cracked. The idea is that fresh air enters the exaust system and will fool
the Lambda sonde.
Next week I will get a (new) second hand one. We’ll see.

The more I think about it, this sounds more and more like the problem as it behaves best when starting
from cold - when the crack wouldn’t have opened up properly.
Questions:
1) Is there an easy way to detect cracks in manifolds. I presume the cr= ack could be very small and
unnoticeable?
2) I assume the manifolds are cast iron. Is it possible to weld cast ir= on with acceptable results?
3) Would replacing an exhaust manifold be an engine out job? I suspect = it would - especially for the
back one :(
4) An unrelated question: On the V6 I was lent while the work was being done on my 24V, the coolant
temp rarely rose above 70 degrees C while driving. In my 24V the temp is at a fairly constant 93
degrees C while driving. It will occasionally go above 100 when stuck in traffic after a good blast. So,
was the other XM running too cold, or is mine running to= o hot?
Please not that I will not be overly pleased by being informed that it is the radiator getting blocked as I
suspect that I will need to remortgage = my house to buy a new one!
BTW has anyone checked out the price of new HT leads? =A3130!!! And tha= t isn’t an errant “1” that
slipped in front of the “30”. How can Citroen justify this? I can buy a premium set of HT leads with a
lifetime guarrantee for my Mini for =A315. I know we’re not comparing like with l= ike here but I think
you’ll agree that there is a significant difference here.
How much does one get for selling kidneys these days?

I’ve heard that the 2 litres are suffering with this problem also. They told me that it was very difficult to
weld. It won’t last for long. Well, that’s what I’m told.
My V6 12V stays at 75-80 degr.C. and will go up to 90 in the city. I think at 90 degr.C the vent will start.
Maybe the temperature is measured on another pace? 95 degr.C is OK I think.

After the previous thoughts, there have been new developments. The happenings went a little like this:
We went out in the car this afternoon. The weather was great and the car performed beautifully.
