Pcv question
My PCV valve is making a rattling sound it is like reverberating thru the valve cover. At first I thought it was valve or lifter noise but if I pull the PCV it stops, and if I just like lay it on the valve cover it will do it. It is pulling good vac and only about 6 months old? And only does it at low idle speeds.
Anyone ever experinse this?
