July 31, 1989

MODEL(S):
All vehicles with 16V 
engine, all m.y.

SUBJECT:
Cylinder head ticking noise at 2000 rpm

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 2000 rpm.

As of 11/88, starting with VIN 067 722 a manufacturing tolerance change has been made to the camshaft sprockets.

If a complaint is filed because of persistent noise; replace both camshafts.
