I have 2 astras both with 1.6 petrol engines, one is auto and one manual
both of these engines are smooth and quiet, I can drive up behind people without them hearing me coming!
without hearing your noise, its hard to say what it is.
it could be a blowing exhaust manifold or a noisy alternator or something else
best get someone to have a listen, do you have a friendly garage?
or did you buy it from a garage? if so maybe they would like to comment?
I also used to have a Civic (spooky)
