Hi Guys,
so randomly this started happening a month ago and would only happen now and then.. today was day 3 in a row of making this noise when starting from cold.
Rev the engine it goes away only happens on idle when cold
I used to have a 2.0T Z20NET Vectra and that blew to a timing chain tensioner so I'm very sensitive to cold start noises!!
Getting it booked in later but wanted to see what other owners opinions are!
Update: 12/3/18 - I have done 40k+ miles since first post & still have the noise but car is running fine.
Cam belt done at 97k & noise is still there when cold. Rules out water pump & cam belt tensioners.
