i have a noise alfa romeo tapping sound in my engine car misses when reved any idea
Welcome Graham to the Forum, more information please, Alfa Romeo, Model, year, Motor size, transmission, type of noise, Colin.
noise it sounds like it is coming from overhead cam and has a miss
What year Alfa Romeo do you have Graham?, Colin.
I gather it is the 156 as per other post.
Following Colin, take your car to an Alfa Romeo Specilaist and get it checked out. There could be a number of things required or service/belt change due. Then you can assess what is urgent etc.
More info is required but a rattly "diesel" noise indicates that the variator is should be changed. A lot of perle skip that when changing the belt and few change the belt with the additional bearing kit.
Cheers
