Thanks for your reply
I was advised to change the oil by a specialist cause he thought it was oil related, I changed the oil 10w40 semi and filter but still noisy. When the specialist looked at it he only had 5 mins but the engine was cold so he couldn't hear what I've been hearing. The car is very good with oil I check once a week but hardly no difference on dip stick, it's usually driven sensibly.
I bought the car off alfa specialist it was a cambelt failure so cambelt was replaced along with a whole new bottom end, this was at 115000 it's now done 133000. To be honest it runs fine can hardly here any noise when driving, just mainly with window down on low revs (eg echoes through mcd drive through) it's an annoying sound I want to get rid of cause I want to sell it soon and want the jtd.
So yeah is it worth paying out loads of money to strip engines etc?
