Slkight tweeting on exhaust

Had a good run in the LSE today & there's a slight tweet on the exhaust manifold, at least I think it's
that. It doesn't sound like tappet noise & isn't very bad, but I would like to sort it.

Anyone know the best way to check for this kind of thing & how big a job is it to sort?

You can pinpoint the leak with a bit of hose, on end stuck against your ear,
and use the other to search round the engine bay until you find the exact
source of the noise.


How big a job to sort depends exactly what it is.

It may be simply a case of tightening a couple of studs on the manifold, but
then again it could be a head off job to drill out broken studs.

Treied and tested for many years... The intention being to listen for
the gust of what ever is blowing / sucking rather than sending the
gust down your ear or sucking your brains out :0)

Our Disco has one too. My money is on worn manifold studs where it
meets the down pipe. Renouned for going. Tighten them and they will be
jingleing away in a week allowing the "spit" usually more noticable
under acceleration.

If it is then it's a manifold off.. refit studs (take it to your
friendly back street oxy bottle owne to get them nice and hot! along
with new studs of course) and refit anlong with new exhuast gaskets
too.

If it's not this then I'm wrong ;0)
