Welcome back to the VXOC FORUM.
Sorry for our lack of support over the last year but MYBB is back and so are we.
Let's get the forum buzzing again... (March 25, 2022)x
Hi all,
I’ve not long had my 60 plate Astra 1.6 SRI, so still getting used to what’s ‘normal’.
The latest thing I’ve noticed is when pulling away at low revs and generally the noise from the engine with the bonnet open for example, is that it sounds like a diesel!
Coming from a silky smooth Civic 1.8 VTEC, this is very much a surprise.
Is this ‘normal’? It’s been serviced, new cam belt and MOT.
Thanks

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)
retrofitted = DAB+, GM dog guard, GM reversing camera
I’ll make a video and post it so you can hear. Inside the car is generally lovely and quiet, but from the outside it’s much louder and rattly than my Civic was.
I’ve only had it a few weeks bought from a used dealer, I pushed for a lot of things to get sorted (new tyre, cam belt etc) and they were under the impression it’s running fine.

This reminds me off when I had Astra-G 1.4 drove up behind someone that was stood in the middle of the road and I blasted the horn damn I've never seen anyone jump so far in my life .

Hard to make out if it's an exhaust blow or mechanical.
Does it change with revs?
Yes, the noise changes with the revs.
I’ve been reading it can be the cam pulleys? Strange thing is the garage put in a new cam belt kit...
I’ve been trying to find a video to compare, I don’t suppose anyone with a ‘healthy’ 1.6 can upload a video?

It could be vvt pulley noise.
Is it worse high up the rev range? https://youtu.be/D-kKLPtIY14
Renault were prone to it, worse when warm engine if I remember right.
NAVI950 , DAB+ & Rear Camera , quick heat, auto lights and rain sensor retrofit

If anything it’s not as noticeable the higher the revs.
Pulling away at low revs sounds a bit like a diesel from inside the cabin.
Mine doesn’t sound anywhere as bad as the video you just shared! (Luckily!).
