[STMO123]

I hear people talking of the dreaded ticking when the manifold gasket is suspected.  As far as I can work out, this stops when the engine warms up and the manifold expands to make a gas tight seal. Now, as the exhaust emissions test and, usually, most of the MOT in general are done with the engine warm or hot, does a leaky manifold gasket equal a failure note? :-/

[Elite Pete]

So long as its not too bad. Mine passed the MOT with it blowing

[Dazzler]

If its quite when warmed up then it won't fail for that as there is no leak, is there??
It would not always fail if it was leaking a little as long as it passed the emissions test, would normally only be an advisory.

OK........so why is everyone so keen to rip their car to bits to fix it?

Because we are all bl**dy obsessive compulsive perfectionists [smiley=2vrolijk_08.gif]

But it would it be cheaper and easier for YOU to just steal another omega  

Oh......I crack myself up

Coz in my case it would be quite nice to start it in the morning and it be quieter than a diesel transit  

Plus theres another reason......where my manifold is leaking its leaking hot exhaust gases straight over the engine thermostat......so....in theory ecu might reckon engine is hotter than it really is.....so fuel ecomony might be suffering...

There, thats answered your question  

[Elite Pete]

Dont say that, im over there tomorrow

I smell something, and it ain't exhaust gases

Where did you say you park yours overnight STMO?

Mine's not posh enough for you, it's only a poxy CDX

Not quite sure what you mean TB  :-/......but on the 2.2's theres an engine thermostat just to left off of the exhaust manifold......my manifold is blowing on the lhs....therefore its possible its getting heated by the hot exhaust gases and giving a false reading to the ecu  :-/

Yup, I was right, smells like BS  

Temp sensor will only really be heat sensitive on the bit suspended in the coolant.  Dont think cheapo tech2 can do live data, as that would show.

As the leak 'seals' when warm, then very little gas escaping.

Would be interesting to get before/after reading to confirm though  :-/
