hi all!
noise is louder when in cold start. goes away or softens very much with warm up.
had a recent cambelt change at an alfa dealer. noise comes mostly from the cambelt area/top back of the engine...

156 1.8 ts, my 2000, 150 000 kms

engine noise warmed up after 5min/3~4 km trip.
while recording the video I didn't notice any ticking, but seems like something was «taped»...

Probably a hydraulic lifter, they make a "ticking" sound when they're not working. Best time to replace them is when doing a cambelt and variator change.
The variator is in the area you describe but it's more of a diesel rattly sound when it's gone. Best time to replace that is when doing a cambelt change.
Oh well, next time....

Most likely the variator slightly worn, had this on my spider ts then the noise went when it was changed with the belts.

thank you both. a bit relieved as is not a sign that the engine will go BANG soon.
frustrated as it could be sorted with the belt change.
I guess it will last until the next belt service, as is not predictable to do more than 5000 km/year.

Don’t count out a faulty tensioner. A loose Cambelt can make the same sound. Did this noise start when the belt was changed?

It sounds like the Variator tbh, I had it on my GTV when I brought it.
Was told it happens when the oil is level is lower (which makes sense as needs lubrication then make a Diesel noise)

coincidence or not, only noticed after the cambelt change. although, occasionally I have had ticking/tapping noises before that, but would go away for months/years. but now is there every cold start.

Sounds like variator to me. An oil change with quality filter and good oil should help. Consider using a heavier oil which should reduce the noise until it is changed.

I think so to that it is the variator, you can buy revision sets but i would place a new one because the timing belt has to come of.

Are they a real Alfa garage? Do they specialise in Alfa’s?
yes, yes, you can find them on alfa romeo website :D
but we never get to know the guy that gets his hands dirty on our cars... you are only allowed to talk with the lady at the desk...

I think you need to have a go at more accurately pinpointing the noise.

A variator noise is usually more diesel like, and will be worse in the first few seconds after startup.

That sounds more like a cam noise, or tensioner issue.

If it is a tensioner you need to get it looked at ASAP, as if the belt goes slack it will cause lots of damage.

Might also be worth checking that the spark plugs are tight. Especially the large one on cylinder 1 as they should have been removed to set TDC.

As it was done by a dealer, any failure or consequential damage is covered by warranty by the garage which carried out the work (consumer legislation). Any work which involves fitting new parts carries a 12 month warranty by statute in the UK. That said, surely there has been some sort of legislative harmonisation within the EU.

If there is an issue, do not touch anything as it would invalidate the warranty. The garage which carried out the work must be given the opportunity to rectify any problems. Unfortunately, if it is not a cam belt related fault, they are within their rights to charge for exploratory/diagnostic time.

However, a decent garage should be happy to check all is well without charging or at very least, have a listen and decide if they want to take things apart to ensure all is well without charging.

It may be wise to talk with them if you are not completely satisfied.

spark plug on cylinder 1 is well fastened.
checked noise again, not sure if it comes from top or bottom. sounded more like bottom of belt area.
will have a talk with the dealer in the next days.
