Cam=car=Twincam ....Not camshaft in this case

Car is as left factory and is untouched apart for the belt being replaced by a local mechanic a year or so ago. Noise wasn't there until recent

I'll have a mess around under the bonnet with the washing up liquid and see what I can find

thanks for your help

I did wonder why you had just taken out a cam

Make sure to check all your vacuum pipes for severance, the slightest cut on a pipe can cause problems, especially under acceleration.

Was it lumpy before the noise developed?
