VW 16V Cylinder Head Ticking Noise at 2,000 RPM
Affects all M.Y. 16-valve engines
Dimensional differences between the camshaft sprockets and the cam timing chain create a rattling noise that can be heard from the cylinder head at approximately 2.000 rpm.
As of 11/88, starting with VIN 067 722 a manufacturing tolerance change has been made to the camshaft sprockets. If a customer complains because of persistent noise, replace both camshafts.
